Speed limits and speed zones

Where a speed limit sign applies, the maximum speed a driver can travel at is the number of kilometres per hour indicated by the number on the sign. Some drivers may be subject to lower speed limits, including some heavy vehicles which are restricted to 100km/h and some learner drivers from outside Victoria. 

A speed limit sign on a road applies to the length of road beginning at the sign, and ending at the nearest of the following: a sign with a different speed limit, an “End speed limit” sign, or the end of the road if the road ends at a T-intersection or dead end.

Speed limit signs may also have the word ‘area’ on them, meaning the speed limit shown applies to the network of roads in the area with an area speed limit sign on each road into the area and an end area speed limit sign on each road out of the area. But another speed limit sign in this area showing a different limit, such as at a school zone, must also be obeyed.

Speed limit signs may also be associated with special zones, such as temporary road works, school zones or shared zones, and apply in a similar manner.

In Victoria, outside these areas and where a speed limit sign doesn’t apply, the speed limit is the default speed limit. In a built up area the default speed limit is 50km/h. The default speed limit for any other length of road is 100km/h. Speed limits apply in a 'road related area' which includes car parks and any area that is open to the public for driving, riding or parking, or is designated for use by cyclists or animals.

Remember that speed limits are the maximum allowed speed, not the speed you should necessarily expect to travel at. Drivers should always drive for the conditions, which will mean slowing down when visibility is reduced, or at other times when it is not safe to drive at the speed limit.

Roadworks speed limits

At roadworks, when a regulatory speed sign (black text in a red circle on a white background) is posted, the speed limit applies. The speed on the sign applies regardless of the time of day, or whether there are workers present. 

Even if no workers are present, there may be reasons for the reduced speed limit that are not immediately obvious. For example narrowed lane widths, no line marking or works being carried out underneath a bridge.

The reduced speed limit applies until you pass another sign with a different speed limit.

It is important to obey the posted speed limit at roadworks sites, not only for your safety and that of other road users, but also for the workers who are on-site.

Advisory signs may also be present at roadworks. These are black on a yellow background and provide advice on the appropriate speed for the conditions. They are not regulatory signs. 

Other signs may warn motorists they are approaching a reduced speed limit. These signs are black text in a black circle on white background with the word 'AHEAD' at the bottom of the sign.

If you notice an issue at a roadworks site on major roads such as conflicting speed limit signs contact VicRoads on 13 11 70. If it is on a local street, contact the relevant council. Find out about who is responsible for the different road types in Victoria and how to contact them.

School speed zones

Motorists need to be aware of speed limits that apply outside all Victorian schools and on route to schools where indicated by signs.

These lower speed limits aim to reduce the chances of a crash occurring outside a school and minimise the risk of death or serious injury if a crash does occur.

Of course speed limits are the maximum legal speed and motorists should always drive to the prevailing conditions and within the speed limit – which may mean slowing down even more outside schools when necessary.

The school speed limit and the type of sign will depend on the usual speed limit of the road adjacent to the school as follows:

A 40km speed limit road sign

Permanent (24/7) 40km/h limits apply outside schools on some roads which otherwise have a 50km/h limit (including roads to which the unsigned 50km/h default speed limit applies). These speed limits are permanent and apply regardless of the day or time.

On some 50km/h roads, including those with high traffic volumes, time based 40km/h signs may be used (see below).

A scool zone speed limit road sign

Time-based 40km/h limits apply outside schools on some 50km/h roads as well as on 60km/h and 70km/h roads. These limits apply from 8.00am to 9.30am and then 2.30pm to 4.00pm on school days (see definition below).

On higher speed roads (80km/h, 90km/h and 100km/h) where there is a flagged crossing, a time-based 40km/h limit will be used.

A school zone 60km speed sign

Time-based 60km/h limits apply outside schools on 80km/h, 90km/h and 100km/h roads. The limits apply between 8.00am to 9.30am and then 2.30pm to 4.00pm on school days (see definition below). Where there is a flagged school crossing, a time-based 40km/h limit will be used.

a 60km speed sign

Electronic variable speed limit signs are found on some roads with 60km/h or higher speed limits (as well as some shopping centres and freeways). The speed limit shown on these signs can change, so make sure you don't travel faster than the limit shown.

What is a school day?

Following the implementation of school speed zones in Victoria, RACV successfully advocated that the State Government should publish the dates defined to be ‘school days’ to remove confusion about when school zone limits apply. The school speed limit dates for 2017 are:

  • 31 January 2017  to 31 March 2017 (inclusive)
  • 18 April 2017 to 30 June 2017 (inclusive)
  • 17 July 2017 to 22 September 2017 (inclusive)
  • 9 October 2017 to 22 December 2017 (inclusive).

Within these blocks of dates, the school speed limit applies except on Saturdays, Sundays and local public holidays. School speed zones may apply locally on weekends or public holidays if signs indicate this on the day. Remember that electronic signs, where the speed limit may vary, must be obeyed at all times. The reduced limits apply on a designated school day even if the school is closed for a 'student free day' or other activity.

These dates also apply to parking around schools where signs indicate that the parking restriction applies on school days (e.g. P 5min school days).
