Default limits and signed limits
Plenty of NSW streets have no speed sign at all, and the road rules fill that gap with two default numbers.
- In a built-up area, with houses, shops or street lights lining the road, the limit is 50 km/h.
- Outside built-up areas, on an unsigned road, the limit is 100 km/h.
- A number inside a red circle is your maximum until another sign changes it.
- An AREA sign, such as 40 AREA, sets one limit for every street inside the area until you pass the end sign.
- A blue LOCAL TRAFFIC AREA sign with 40 (ZONE on older signs) works like an area limit. Bike riders, walkers and children use those streets too, so look out closely.
- Roadwork and electronic speed signs are real limits, even when no workers are in sight. Break a roadwork limit and you get a fine plus demerit points, as for any speeding.
Buildings beside the road and no sign in view is a classic DKT trap. The answer is 50 km/h, not 60.
