WATCH: Driver clocked doing over 100mph driving grandmother's '˜motability' vehicle in Hertfordshire

The motorist was filmed by a Beds, Cambs and Herts Policing Unit officer travelling at more than 40 miles over the speed limit with no insurance.

The ‘motability’ scheme provides vehicles for disabled people, with specially-adapted and easily accessible cars.

He was reported for excess speed and driving without insurance after being stopped on the A602 in Hitchin on Tuesday night.

An officer from the BCH Road Policing Unit tweeted to say: “Driver hits over 105mph driving home from work. He is in his Nans Motability vehicle, he is a named driver for SD&P only.

“Reported Excess speed & no Insurance. Enquiries in hand with finance company for terms of use.”
