That’s interesting.
The dolly / commercial trailer thing seems to have been jumped on by TILLY and fed out to some police forces and DVSA areas that take her word as gospel.
I had a friend round for dinner the other day and she is a trainer for DVSA roadside enforcement. She seems of the same opinion as me re the dolly thing.
Have you a link please? If they’re commercially available that makes things interesting
I was meaning field only dollies. Some are big things that would require there own trailer to get them to the field.
As for normal ones I have driven them for years. The biggest problem is they are rarely fitted with breaks and if they are there is little in the way of balancing so you end up breaking squiffy
