Regulatory sign
Speed limit (30 mph)
A white circle with a red ring and a number sets the maximum speed in miles per hour. 30 mph is the usual limit in built-up areas where there are street lights, unless another limit is signed.
When you see it
- ◆ The number is the maximum legal speed in mph, not a target.
- ◆ A system of street lights usually means a 30 mph limit unless signs say otherwise.
- ◆ Reduce speed further in poor weather, traffic, or near schools.
- ◆ Many residential streets are now 20 mph -- always obey the posted sign.
