50 km/h Speed Limit on Local Streets in South Australia

Since 1 March 2003, the speed limit in built-up areas of all South Australian cities and towns is 50 km/h unless there is a sign with a different speed limit. This lower speed limit has been introduced to help reduce crashes and make local streets safer for all road users particularly children, pedestrians and cyclists.

The new speed limit is a ‘default’ speed limit which replaces the previous general urban speed limit of 60 km/h in a built-up area. If you do not see a speed limit sign on any particular street or road in a built-up area then you must not exceed 50 km/h.

Streets and roads where the speed limit is higher or lower than 50 km/h are clearly marked with speed limit signs. Examples include many main roads, road works, 40 km/h areas, 25 km/h school zones and children’s crossings.

The information on this website tells you what you need to know about the new 50 km/h speed limit and who to contact for more information.

Remember, if in doubt and there is no speed sign, the speed limit is 50 km/h in a built-up area.
