Driving on Sunday on a dual carriageway miles from anywhere at 65mph.
Saw a police van on bridge overhead - no worries as doing 5mph under speed limit.
Glanced at TOMTOM and it said speed limit was 50mph - but it's often wrong.
No signs saying that it was other than 70mph from when I joined carriageway.
It was miles away and I can't go back.
How can I check the speed limit on this specific road - is there a wesbite?
