About Course
20 mph limits are now much more common, and since September 2023 most former 30 mph roads in Wales have a default 20 mph limit. This course explains in plain English how to tell what the limit is, the difference between 20 mph “zones” and “limits”, and simple ways to stay comfortably within the limit.
