7.5 t weight limit at Dunstable area wide

I went through Dunstable a few weeks ago and noticed some signs for the weight limit referring to the A5183…couldn’t work it out. So the road that everyone knows as the A5 is the A5 no more. Handy that…it’s my fault for not checking every county councils’ website to see what changes they’re making/ have made…I was wondering for a while if I was going to get a ticket but I seem to be in the clear. Going through Dunstable is bloody slow anyway at the best of times!
