What is the speed limit of a single carriageway road?

Explanation: 60 mph is the maximum speed on a single carriageway road. Be aware of this especially in instances where a national speed limit dual carriage way filters down to a single lane. The speed limit will change but may not be signposted. Slow down gradually ahead of the change in the road. Learn speed limits for different roads from The Highway Code.
