The point here is that someone else was driving at the time they were stopped, the police should not accept it, got no time for uninsured drivers myself.
I hope ther police do not let you have it, as they should not, if the twat can afford petrol to use it he can afford insurance if he can't then he should not drive it.
I also hope they do the person who allowed him to drive as he has a LEGAL OBLIGATION to ensure it's usage is legal ie insured.
