Treadcam could be on the way

Treadcam is a Procontour machine that has been developed in Germany that is placed on a road and uses lasers to check the state of tyres on passing vehicles.Details of any tyres below the legal limit are sent to a waiting police officer down the road,who then pulls over the driver.
The device will cost £43,000 to fit so decisions will be made in the future on whether this is a viable proposition to be implemented in the uk.
