Talk:Speed limits in Australia

School zones

In the ACT, the school zone limits are from 8am-4pm inclusive, but I believe other places do this differently?

In NSW there is a morning (8:30am-10am) and an afternoon (2:30pm - 4pm) "session" for school zones. That is, during the middle of the day it is the same speed limit as it is at 6pm.Garrie 04:10, 21 February 2007 (UTC)

Qld is similar to NSW as described above. WikiTownsvillian 04:33, 21 February 2007 (UTC)

In Western Australia we have 2 sessions for school zones. morning (7.30am to 9am) and afternoon (2.30pm to 4pm), there is also no speed restriction based on what speed the road itself is, all school zones are 40km/hr, outside of these session times the speed is the normal road speed. —Preceding unsigned comment added by 58.6.20.173 (talk) 02:58, 23 November 2009 (UTC)

• COMMENT Some places in NSW do have variants in regards to speed, and time. For example a school in Cronulla used to have 40km/h speed limits from 08:00 to 15:00 without any time breaks from 09:30 to 14:30. This was resolved somewhere around 2011. Kulnura used to have 60 km/h zones. Two more places that I know that have done this were Kurrajong, which had 08:30 to 09:30 and 15:00 to 16:00, and Broulee, which had 08:30 to 09:30 and 14:30 to 15:30. I'm not sure whether Kurrajong, Kulnura or Broulee had their signs fixed up or not, but anyway I just wanted to say that school zone speed and time variants do exist. --SlitherioFan2016 (talk • contribs) 21:24, 12 December 2016 (UTC)

Unlimited Roads

But what for the Unlimited roads at least found in Northern NSW? Roads like the Lions Road (between Rathdowney & Kyogle), and some roads out from the pacific highway to places such as Woorim have an unlimited sign with the advisory 'Drive to Suit Conditions.' —Preceding unsigned comment added by 211.31.189.250 (talk) 13:27, 31 March 2008 (UTC)

If you can find a reliable source (e.g. a piece of legislation etc.) saying that there's any unlimited roads in NSW (or anywhere in Australia now) feel free to insert the information. However, in the meantime I'd advise you to look into the matter (especially if you drive on Lions Road and think it unlimited), I'm sure you'll find that Lions Road is just derestricted (i.e. the default speed limits still apply).Jgillett (talk) 09:56, 28 May 2008 (UTC)

There are no unlimited roads in Australia. The Northern Territory was the only location in Australia who had unlimited roads but now has a default limit of 130 KM/h Bidgee (talk) 10:42, 28 May 2008 (UTC)

The speed limit on these de-restricted roads in NSW are 100km/h. If you refer to the RTA's Road Users' Handbook it says that when you pass one of these signs the state limit of 100km/h applies. Here are photos of such signs used in NSW Wyp (talk) 05:55, 22 June 2008 (UTC)

The speed derestriction signs were typically placed by NSW Councils, such as Tweed. This was permitted under old versions of RTA's "Speed Zoning Guidelines". However, the legal authority for Councils to use speed derestriction signs was removed by Version 2.3 of 2004 of those Guidelines.

To date, it is desired that (many) existing speed derestriction signs be removed, and for those knocked-down, or for those that have reached the end of their lifespan, that they NOT be replaced whatsoever. A driver then has to determine if the subject road comes under the 'RURAL DEFAULT' (ARR) or not. You do this by referencing the DEFINITION held under the ARR (Australian Road Rules) dictionary.

In education terms for all road users', this is/will be spelt out in the "Road Users Handbook" -the NSW driver education book. All jurisdictions will apply same.

NSW RTA as 'State Roads Authority', will retain sole authority to re-use the speed derestriction signs in time IF DESIRED, BUT their use will *only apply* per the definition held in AS1742.4 of 1999 (still current).

Here, the meaning is; "Speed derestriction" (Catalogue No. 'R4-2'): "The speed derestriction sign shall be used where permitted by State or Territory regulations, at the end of a linnear speed zone or a general urban speed limit to indicate that no speed limit applies to the road beyond the sign".

This legal meaning applied to AS1742.4 of 1999 is harmonised with the "United Nations Conventions on Road Traffic, Road Signs & Signals". Athol highlights this. Here, the meaning in turn is vis; "Sign C,17a - End Of All Local Prohibitions Imposed On Moving Vehicles". Australia is contracted to the Road Traffic portion of this Convention, and we are bound to not misrepresent international road traffic signs in legal interpretation. (In respect to this sign, both NZ and GB are in technical legal breach, the sign does not represent 'Open Road' or 'National Speed Limit').

That said, when on a derestricted legth of road - L, P1 and P2 drivers remain (can be) 'speed limited' by way of "License Conditions". Heavy vehicles remain speed limited, regardless under ARR25 too. Jeremy H. Pritchard. —Preceding unsigned comment added by 121.44.49.161 (talk) 07:48, 21 July 2008 (UTC)

Australia is not a signatory to the United Nations Convention on road signs and signals, Vienna, 1968 so we need only consider the Australian Road Rules. Alex Sims (talk) 10:12, 21 July 2008 (UTC)

Alex, as I mentioned above, whilst the Commonwealth did not ascede to the Signs & Signals portion (a shame really), the UN Convention on Road Traffic desires member states that do not contract the Signs portion, - ensure continued uniformity - of road signage used.

To that end, both the AS1742.4 of 1999 and ALL STATE and Territory MUTCD's and Speed Zone Guideline adoptions of same are now harmonised with the UN Convention 'Signs portion' in relation to 'meaning'. Additional legal mode outside 'roads' as to ownership application etc also apply.

Quite factually; it is not for any Australian agency or individual to take international property and mis-represent that property to international traffic in any manner, and I have for some years now 'suggested' to ALL our road transport agencies, and the Commonwealth Legal Drafting Office, that we follow international interpretation with this sign, as a 'requirement'.

Australia has chosen to comply with the meaning held in the Signs portion - in its AS1742.4 of 1999 edition. A major part of that harmonisation effort is therefore complete.

This all leads me to suggest the inclusion of an 'end speed-limit sign' picture in the Wiki article, we are now about to start using a greater number of them! NSW will also on occasion, use with this sign a "DRIVE TO CONDITIONS" template underneath it. Both ARR25 (1) & (3)b apply in relation to 'meaning' thereof, in turn this is taken from AS1742.4.

ARR25 (3)b 'under another law of this jurisdiction' also applies in regards to use of the (//) sign. (Now, here in NSW we legally reference AS1742.4 in our Speed Zoning Gudelines, and we *MUST*, nor can we misinterpret such signs included within that federal document.

I am not overly concerned in a legal sense with ARR25(1). Any readers who come under notice for 'exceeding the speed-limit' when on a signposted (//) length of road, please advise. I can be reached on +61 3 8689 0001 (Day) and would appreciate your experience. Mr Jeremy H. Pritchard. —Preceding unsigned comment added by 203.51.93.210 (talk) 08:24, 29 August 2008 (UTC)

Australia did not sign the UN Convention on Road Traffic 1968 either so I can't see any basis for your argument. The Australian law applies, not an international convention to which we are not a signatory. (And if we were a signatory, we would make our laws reflect the convention). Alex Sims (talk) 09:39, 29 August 2008 (UTC)

Alex, read gain. We contracted the 49' Convention. We are still bound by that. This is where law and application becomes arguable.

I have been through the courts *many times* and was involved in the 'speed' legislation ARR process, and stand by my comments to date.

For your reference, AS1742.4 of 1999 that governs, technically, what signage state and territory agencies may apply to the road network has been updated by "DR 07228". In this, the speed derestriction sign is dropped entirely (public comment closed mid 2007). This means for AS1742.4 when it is updated (rubber stamped), in academic theory, no elected politician, or roads agency can 'demand' or 'require' its re-introduction, in any applicable manner, onto their respective state roads.

It also means, to a greater extent, that your reliance on ARR as sole interpretation will stand a greater chance of success, in the lower court.

I will, in time, test NSW Parliamentary authority over that of our road agency employees and against national standards (the new AS1742.4 WHEN the update reflects). You never know, we might just legislate a 'prima facie' rural speed allowance again. JP.

NT Urban Speed Limit

Using this 2005 brochure as a reference, the entry for the default urban speed limit in the NT was changed from 60km/h to 50km/h; however, this plan did not go through. If you refer to the Road Users' Handbook published in December 2007 (and thus being newer than the other reference), it shows that the default urban speed limit in the NT is still 60km/h. Wyp (talk) 05:55, 22 June 2008 (UTC)

I don't trust the Users' Handbook for many reasons (I use to live in the NT). The Change did got ahead NT police pleased with response to new speed limits (June 2, 2005) and I can't find anything to say that this was axed and only one source says that it's 60. Also when I was in Darwin, the urban speed limits were 50km/h (sign posted as well). Bidgee (talk) 06:13, 22 June 2008 (UTC)

Also NSW does not have a derestriction speed limit [1].May want to check out this as well. [2]. Bidgee (talk) 06:36, 22 June 2008 (UTC)

Hi Bidgee, the Northern Territory Traffic Regulations 2007 here shows that the default is indeed still 60 km/h. It specifically states that rule 25(2) of the Australian Road Rules (which states a 50 km/h default) does not apply to the Northern Territory. Councils may choose a 50 km/h default for particular areas, but for the territory as a whole, it is still 60 km/h. As this is the actual road traffic legislation, in a legal sense, what this document says will prevail. As for derestriction signs in NSW, new derestriction signs are not to be installed; however, there are many still around, see this link here for examples, I know of plenty more but don't have photos. Also, refer to page 52 of the Road Users' Handbook here. Whilst in theory they mean 100 km/h, they're still called derestriction signs, even by the RTA and they do exist. The derestriction photo I added on the main page of this article was taken in NSW this year so they are indeed still in use. Wyp (talk) 07:14, 22 June 2008 (UTC)

I'm going to add a section (Once I can get a few more sources) about de-restriction sign since it has different meanings (NSW it's a default speed limit, NT it was unlimited speed limit). Bidgee (talk) 08:48, 22 June 2008 (UTC)

Relating to derestriction signs in NSW, up until July 1979, they did sort of mean unlimited. Prior to this adoption of the 100 km/h state limit, the derestriction sign meant a prima facie speed limit of 80 km/h applied -- you could go over it as long as it was safe. 85th percentile speeds went from 119.5 km/h to 113.1 km/h after the 100 limit was implemented. Whilst NSW still has derestriction signs, I believe the NT got rid of them completely with the introduction of the 110 km/h default. Wyp (talk) 09:27, 22 June 2008 (UTC)

Yep the NT removed them totally and was replaced with the 110km/h default with some sections of the Stuart, Arnhem, Barkly and Victoria Highways replaced with 130km/h. It hasn't worked though (lowering the road toll). Bidgee (talk) 10:17, 22 June 2008 (UTC)

In spite of the RTA offically saying that they aren't in use, there are still quite a few physically in place in NSW. There are moves under way to get the remaining ones removed but some councils are still installing them, contrary to RTA guidelines. Once all are removed, the idea is to restore the meaning of the sign to its proper definition according to the UN agreement that Australia is legally bound to, which defines it as end of all speed limitation, not prevailing rural default. In the meantime, the sign is no longer officially in use in NSW but some remain in place. --Athol Mullen (talk) 11:33, 22 June 2008 (UTC)

Hi Athol, I've added your photo to my de-restriction listing page here and have attributed the photo to you as per the CC licence. However, if you would like me to remove the photo, let me know and I shall do so. Wyp (talk) 12:25, 22 June 2008 (UTC)

No problem. I'm happy for you to use it. Besides, the CC license means that I couldn't prevent you from using it even if I wanted to. Note that the photo also has its geo data included in commons. The photo was taken at the intersection of the Bylong Valley Way. Last year, I also noted derestriction signs still in place on a side road off the highway between Bathurst and Cowra. They're not rare and they're not just in remote locations. --Athol Mullen (talk) 12:45, 22 June 2008 (UTC)

I've seen some in the Riverina and South West Slopes of New South Wales but some have been removed. In the NT I only missed out the the unlimited speed limit by a few days :(. NSW must love it's past Image:Route 41 Wagga Wagga sign (Mills St).jpg is no longer Route 41 since it's been bypassed yet the sign is still there and the good old Image:Road_distance_marker.jpg in miles. Bidgee (talk) 12:59, 22 June 2008 (UTC)

Urban Freeway Speed Limits

It's been added that "most urban freeways in Australia have a speed limit of 100 km/h", however, many urban freeways are 110 km/h. For example in Sydney, (parts of) the M4, M5 and F3. Similarly, parts of the M1 in Queensland is also 110 km/h. Wyp (talk) 08:30, 12 July 2008 (UTC)

No one's argued otherwise so I've gone ahead and updated the page. Wyp (talk) 11:49, 13 July 2008 (UTC)

There are also 90 zones on some, including parts of the M2 and M4 in Sydney and the 2 completed freeway sections of the Newcastle Inner City Bypass. In the latter case, each section was opened as an 80 zone and later raised to 90 following lobbying. One had already been raised to 90 before the other was constructed but the same thing happened! --Athol Mullen (talk) 12:34, 13 July 2008 (UTC)

If you start really digging into it, Melbourne has the Western Ring Road with a variable limit of 80/90/100 km/h (and possibly lower?) and the inner section of the West Gate Freeway at 80 km/h. 100 km/h seems to be the 'default' here and any others are 'exceptions'. Wongm (talk) 13:07, 13 July 2008 (UTC)

If may be the default in VIC, but in NSW I can't think of a single fixed 100 zone on an urban freeway. The M7 also has a variable limit with a maximum of 100. Part of the M4 has a variable limit with a maximum of 90. Perhaps we should be saying that there is no standard and they're all over the place like a dog's breakfast.  :-) --Athol Mullen (talk) 23:47, 13 July 2008 (UTC)

30km/h speed limits?

I note that someone has added the following sentence to the article: "Many local government areas have unilaterally applied lower limits, such as the City of Sydney introducing 30 km/h zones in many areas".

Apart from the sole exception of Druitt St (next to Town Hall), I do not believe that there are any 30km/h zones in the Sydney LGA. The Royal Botanic Gardens is also zoned 30km/h; however, as that only applies to the park's internal roads, it doesn't really count. As such, I don't think I agree with the phrasing that 30km/h speed zones apply in "many areas" in Sydney. Can someone justify/revise this? Wyp (talk) 03:12, 27 March 2009 (UTC)

There are 30km/h zones in Parramatta. Especially on Argyle Street and Station Street East. It is also there on Macquarie Street. AussieCoinCollector (talk) wish the entire world's COVID-19 status was like WA, 275+ days of no local cases :) 21:55, 14 January 2021 (UTC)

The 30km/h limit in that section of Druitt St was imposed by RTA/State Gov in an attempt to reduce the pedestrian crash over there. Sydney Council and every other council in NSW do NOT have the legal power to set speed limit along public roads. (The internal roads in Royal Botanic Gardens are not really public roads, but I suppose lawyers may have a fun time debating this point) 124.149.164.229 (talk) 13:43, 12 May 2011 (UTC)

Also 30 kmh limit on the road behind Parliament House- is that part of the Botanical Gardens? Centennial Park also has a 30 limit posted after 9 am, after an agreement was reached with cycling clubs in 2012 or 2013, after attempts to introduce speed humps were resisted, who traditionally have used the Park for group training. They agreed to restrict training rides to early morning.

I attended a Road Safety Seminar at Parliament House c 2010 where (then) RTA road safety representatives said they wanted the power to use 20 and 30 kmh limits , because 10 was too low in some cases and 40 was too high. A 20 or 30 limit would give them more flexibility for dealing with shared paths or shared zones and other situations. Apparently the ARR only mention 10 and 40 limits, and the MUTCD (signs manual) only allows or lists as allowable 10 or 40 signs, so my reading of all that is that 30 signs are possibly not legally enforceable.

Rural Default Speed Limit in the ACT

I have been in correspondence the Office of Transport in the Department of Territory and Municipal Services. They have informed me that the ACT is not classified as "all urban"; rather, a default rural speed limit of 100km/h exists as specified by 25(3)(b) of the Australian Road Rules. They have also informed me that the 2010 version of the Road Rules Handbook will likely incorporate this information. As such, I have updated the ACT's default rural speed limit information accordingly. Wyp (talk) 00:05, 31 March 2009 (UTC)

Default speed limit in WA outside urban areas

I've added a ref for the WA speed limits, being the Drive Safe book. I was going to cite the Road Traffic Code 2000 - Reg 11, Speed limits generally, but it doesn't mention the 110 "open road" limit - but it is explicitly described in the Drive Save book, p47:

The speed limit that applies in Western Australia outside ‘built-up’ areas and where there are no speed limit signs is currently 110km/h.

The Rad Traffic Code code mentions the default 50 kh/h limit (in clause 2). Does anybody know why the 110 limit is not in the Code? Is there an updated version somewhere? Mitch Ames (talk) 07:45, 16 February 2013 (UTC)

It's in Reg 3 which defines the term default speed limit (which is 110). (I used this search to find it ) Alex Sims (talk) 08:58, 23 February 2013 (UTC)

Thanks. Mitch Ames (talk) 13:43, 23 February 2013 (UTC)

Multiples of 10

The lead paragraph says "All speed limits [with specific exceptions] are multiples of 10...", but the reference is the NSW speed zoning guidelines, which applies to NSW, not the whole country. Do someone have a reference that covers the whole country? Mitch Ames (talk) 08:31, 23 February 2013 (UTC)

AS 1742.4 for 0 digit, section 2.1.2c. I haven't got around to adding the reference to the relevant Australian standard as I need to recheck the section (and unfortunately these are not conveniently online :-( ). I used the NSW example as was readily accessible in both readability and access. Alex Sims (talk) 08:52, 23 February 2013 (UTC)

Note that AS 1742 is not likely to be sufficient as a reference, because an Australian Standard is not the law. There's a big difference between "AS 1742 says X shall happen" and "X happens". Here is an example of the road rules apparently not following the standard:

Until a standard is legislated, or passed as being law by a state, territory or federal government, then it may only be considered a guideline not a law. ...
Drawing a direct comparison to Australian Standard 1742.4, and speed limit signage and zones that can currently be found in the ACT, it is very apparent that the ACT Government, it’s roads agencies and contractors do not come close to following the standard. [3]

Here are a couple of examples of state govt bodies explicitly stating that they will follow the standard: [4][5] - not actually for speed limits, but demonstrating the sort of reference that we might need for speed limits, ie stating explicitly that the standard is being applied. Mitch Ames (talk) 13:23, 23 February 2013 (UTC)

I'm starting to worry a bit when you use an anonymous blog as a source (I used to be an ambulance officer/paramedic, have driven and been driven (remember we take turns drive/care for patient) with police escort, does that make an authority too if I write a blog :-) ). Hypothetically, before I spend numerous hours chasing down references, what sort of referencing do you need? I gather you want a set of references for each state/territory at a minimum that chains:

• The law that gives the power to regulate the erection of signs to the road authority (7 references)
• A reference from the road authority that they follow AS1742.4 when setting speed limits (7 references)
• No reference about signs as we assume that signs limits follow the limit that is set
• The relevant phrase from AS1742.4 (a single ref)

Alex Sims (talk) 22:45, 23 February 2013 (UTC)

I agree that the blog is not necessarily a reliable source - but it's not being used to support a statement in the Wikipedia article. The blog entry merely shows that someone else agrees with me that "a standard is not the law" and "speed limit / laws do not necessarily follow the standard". The reference(s) that we need to support the statement "[with certain exceptions] all speed limits are multiples of 10" would be:

Ideally:

• Some published WP:RS that says this (covering the whole country), whether or not it mentions AS1742 (because the article statement doesn't currently mention AS1742).

Failing that:

• A reference that says "all states/territories speed limits follow AS1742", or a reference for each state/territory that says "[this state's] speed limits follow AS1742".
• The relevant phrase from AS1742, ie the one that says "speed limits shall be multiples of 10".

We don't need any mention of signs at all, because the statement is about speed limits, not signs. (Although the article possibly needs a separate section "Signs" that says things like "speed limits are indicated by signs [description], signs follow AS1742, default speed limits may apply if there are no signs, END signs denote end of a specific speed zone" etc. Ie separate the details of the speed limit values from the details of the signs that denote where the limits apply.)

We don't necessarily need references to laws (or Acts of Parliament) giving legal power to road authorities to set speed limits or erect signs - unless we state explicitly that limits/signs are set by those road authorities. The reference requested is for the value of the speed limits, not for the authority to set those values. Mitch Ames (talk) 03:08, 24 February 2013 (UTC)

Advisory signs ending in 5

The lead paragraph says "Advisory speed signs for curves or other road obstacles generally end in the digit five". I suggest that we need a reference for this, and/or to qualify it. In the last few days I have driven past at least three advisory signs - in WA - that ended in zero (on curved off/on ramps for Kwinana Freeway). Mitch Ames (talk) 08:52, 23 February 2013 (UTC)

Again it's in the relevant Australian standard (but not the same one as for limits. This on first reading was for it to be a multiple of five, it would appear though that Road Authorities seem to favour the last digit of five in practice unless low. I've seen one (and only one) in SA at 30km/h which was reduced after a crash from 35 km/h. Alex Sims (talk) 09:01, 23 February 2013 (UTC)

"it would appear ... that Road Authorities seem to favour the last digit of five ... I've seen one (and only one) in SA That (text in italics) looks very much like OR, and in only one of the states. In the absence of a reference that supports it, I propose that we delete the sentence "Advisory speed signs ... generally end in the digit five". (Especially since those signs are not "speed limits" anyway.) Mitch Ames (talk) 11:00, 23 February 2013 (UTC)

This is a talk page, that was a comment,. I think you are getting overly picky. Roads are a state responsibilty but are uniform across Australia with minor variations between states. To chase down references for every state is getting a bit ridiculous. I've had several traffic engineers quote the 5/0 rule at me and it appears this is a result of historical practice based on Australian standards. You need a survey of signs to verify the proportions of advisory signs or accept opinions from industry. Alex Sims (talk) 11:59, 23 February 2013 (UTC)

"You need a survey of signs to verify the proportions of advisory signs or accept opinions from industry" - Agreed. The former would be OR if done by Wikipedia editors, but a published survey by someone else, or "opinion from industry", is what what I am asking for. Perhaps the "several traffic engineers [who] quote the 5/0 rule" could provide a verifiable published source? Mitch Ames (talk) 01:32, 24 February 2013 (UTC)

I've seen a mix of *0 and *5 km/h advisory speed signs in Australia. Yes this is OR but I want to point out what we have on Commons, to try and clear up the matter. 55 km/h (incorrectly used) in NSW, 35 km/h for a bend in SA (though was taken in 2005) and 40 km/h for a bend in QLD. Bidgee (talk) 11:22, 23 February 2013 (UTC)

Yes, the advisory signs with a yellow background do tend to end in 5. Although I think we are talking here about the standard speed limits with a red circle. --SlitherioFan2016 (talk • contribs) 21:34, 12 December 2016 (UTC)

In the absence of a reference, and several exceptions to the "ends in five" rule, I've removed the sentence. Mitch Ames (talk) 12:02, 12 March 2013 (UTC)

Please do not remove it, most of the advisory limits I have seen are in 5's. Infact here's an example of some ending in 5: (on the top of my head)

5km/h: Galston Gorge 15: Speed Bumps 25: Also speed bumps 35: Bends on the Great Ocean Road 45: Same as well as many in NSW 55/65/75/85: Princes Highway and other motorways in NSW 95: Waterfall Way before Dorrigo

Victoria phasing out 75

Resolved

Regarding the recently added "Victoria phased out 75 km/h limits ...":

I do not think that a historical change in the speed limit in one state is appropriate for the lead section - unless this was the removal of the last non-multiple of 10 (other than the SA exception). If it was the removal of the last non-multiple of 10, we should say so explicitly. However in that case we need a better reference. The current reference says 75 was phased out to "achieve credible speed limits which were uniform with the rest of Australia". It does not say that the phased-out 75 was the last non-multiple of 10 in Australia. Mitch Ames (talk) 02:29, 24 February 2013 (UTC)

In the absence of any objects, I've removed the sentence. Mitch Ames (talk) 11:58, 12 March 2013 (UTC)

Prima facie speed limit

@Changa101: / IP 101.191.60.89: Can you please explain your recent edits to this articles? The edits appear to introduce incorrect information (note that Wipedia articles need to be based on reliable sources). The source cited in the article ("A Review of Rural Speed Limits in Australia") specifically states "Until 1971, Victoria had a prima facie rural speed limit of 50 mph (80 km/h)" (page 31) [p39 in PDF file] and "in NSW ... roads subject to the 50 mph or 80 km/h prima facie speed limit" (page 76) [p84 in PDF file]. You have not provided any sources for your changes, despite multiple requests – please communicate why you think these changes should be made! Note that disruptive editing, such as vandalizing pages by deliberately introducing incorrect information, may result in you being blocked from editing. - Evad37 [talk] 00:38, 26 February 2016 (UTC)

The only place to have speed limits higher than 150km/h is the UAE, with a limit if 160km/h AussieCoinCollector (talk) wish the entire world's COVID-19 status was like WA, 275+ days of no local cases :) 21:54, 14 January 2021 (UTC)

110km/h rural speed limits in NSW

Is there a reason that my edits keep getting reverted. The default limit west of the Newell Highway is 110km/h and the document I sourced also says

• High-quality rural divided roads. • Undivided rural road with low traffic volume west of the Newell Highway.

In this case, it's why the Newell and Mitchell Highways qualify for 110km even east of the Newell Highway.

The only exceptions to this is if it's not sealed. But that also applies east of the Newell Highway.

If you don't believe me, then fine, the innocent Wikipedia readers will just gain the wrong knowledge and I will stop editing here.

Above the table is an explanation of the table. The default speed limit, is the limit set by statute as to what applies in at the absence of any particular zoning or signage. The highest zone is the highest speed zone in that state or territory. The zone is set by policy, usually by the state road authority. The information you are inserting answers a different question, that of what figure the road authority uses in each particular circumstance. This is outside the scope of the table, hence the reverts. You may wish to work "speed zone setting policy" somewhere else in the article. Alex Sims (talk) 06:04, 12 January 2021 (UTC)

Well the default limit west of the Newell is 110km/h. It's a weird case but facts. It is not about zoning as there is more area West of the Newell. It is not outside of the scope as it is split in half. It's only in NSW though.AussieCoinCollector (talk) 22:21, 12 January 2021 (UTC)

The table answers the question, in the absence of a sign, what is the speed limit outside an urban area? This is set by the NSW Parliament through the Regulation "Road Rules 2014". A zone is set by the road authority. It is not the default limit. A zone can be set above and below the default limit. You have identified the policy for what the road authority does in relation to zones. The road authority cannot change default limits, that is set by the Parliament. I'll revert your change to the default limit which is incorrect. Alex Sims (talk) 01:06, 13 January 2021 (UTC)

5 is not an official speed limit unit

As far as I'm aware, the speed limit of 5 km/h, while common in privately owned parking lots and driveways, is not an official or legally enforced speed limit unit in any jurisdiction; the lowest of such being 10 km/h in shared zones.

Should we change the introductory sentence in the article from "range from 5 km/h shared zones" to "range from 10 km/h shared zones" to reflect this? --DL6443 (^Talk/_Contribs) 07:01, 6 January 2024 (UTC)

Your belief is probably correct, but given that the whole article is so poorly referenced, a proper source for the claim would be nice to have. HiLo48 (talk) 22:12, 6 January 2024 (UTC)

@HiLo48: I have found official sources from Transport for NSW and QLD Dept of Transport and Main Roads supporting this: NSW (section 9.2) and QLD (section 2.2) both state that officially recognised speed limits must be multiples of 10 and the lowest is 10 km/h in shared zones. However, I am still yet to find equivalent documents for the other jurisdictions.

As for sources in other parts of the article, it may be worth considering gathering a team to do some wider article cleanup, as I do feel like chunks of it needs to be rewritten. --DL6443 (^Talk/_Contribs) 05:22, 8 January 2024 (UTC)

Speed derestriction

As at 2024, no Australian jurisdiction operates speed derestricton (//), or a prima facie limit/allowance.

AS1742.4 is the Australian Standard for speed control signage. Our states are sovereign, and can set their own speed restrictions, (or derestriction, despite AS174.4), but,- the speed restriction signage used, must comply with the Standard insofar annulis, its colors, numeral legibility/font, the background materials used - etc, for uniformity.

In setting speed limits, a jurisdiction like NSW operates, "The News South Wales Speed Zoning Guidelines" (SZG), this work holds the technical detail for speed limit application, sign sizes, spacing, and number of signs needed, both for the State authority itself, and for the local government tier. It by nature, references the signs held in AS1742.4.

Other jurisdictions, in referencing AS1742.4, for their own application of speed controls, will reference such work as "MUTCD" (a term adopted from the US many decades ago) - meaning 'Manual of Uniform Traffic Control Devices'. Queensland, for example, operates an MUTCD!

Regardless of a States name given to 'speed control signage' sourced from AS1742.4, there will always be some application differences, either in approach to limit setting, the number and spacing of the signs along a road, and the sizes required, though the jurisdictions do try and keep in harmony with AS1742.4.

The signs in AS1742.4 in turn, take their design cues, and meaning, from the global system (UNECE,+ Vienna protocols), an obvious difference, are our speed limit signs are 'square cut', compared to the global systems 'circular cut' signage, and this latter bit, relates to headlight glare reduction. — Preceding unsigned comment added by Jeremy H Pritchard (talk • contribs) 03:08, 8 December 2024 (UTC)

 Comment: Refactored above post which incorrectly deleted old discussion from above section called "Unlimited Roads", which apparently is "as much once linkable, verifiable info was outdated, no longer available." according to Jeremy. Fork99 (talk) 20:51, 8 December 2024 (UTC)
