there is currently and has been for a couple of years.
due to no tax the right to clamp then sieze and crush cars with no tax.
how they gather locations of said vehicles would i "imagine" mostly be 1 or 2 ways ,
by the registered address and looking to see if vehicle is on the public highway.
and secondly by such vehicles being reported on the road by members of the public.
i can only imagine in your example that it was mearly a case of bad timing that your vehicle was seen " within 35 min's ".
This is enforced through means of the local police and their contracted recovery companies .
i have never actualy heard of a charge to remove the clamp , however that does not mean this is not done ,
I do understand that they will not remove the clamp or return said vehicle until the vehicle is again tax'd " as for back tax i have no clue sorry" however if the vehicle has been collected by the recovery company and impounded , i would imagine a cost would have to be paid to release the vehicle.
The vehicles are clamped until the recovery company can come and tow away said vehicle. this is obviously done to stop the vehicle changing location and being used .
These vehicles are then taken to a compound to await crushing.
any vehicle on a sorn or without tax has no place what so ever being on the public highway " for any lenght of time " .
that being said if the tax has just run out there maybe some time given but that again im not entirely sure upon
The adverts on the TV regarding this should be classed as a public warning and have been going on a long time.
