Unless signs show otherwise, what’s the national speed limit for a car or motorcycle on a motorway?

Explanation: The national speed limit for a car or motorcycle on a motorway is 70 mph. Lower speed limits may be in force; for example, at roadworks. Variable speed limits also operate in some areas when the motorway is very busy. Cars or motorcycles towing trailers are subject to a lower speed limit.
