From a legal perpective I would be interested to see the legislation confirming the effective cancellation of an MoT certificate for failure of an early test. An ammendment to the Road Traffic Act would be required.
An MoT test only confirms the state of a car at time of test and the driver is subsequently responsible for ensuring that the vehicle is roadworthy throughout the valid period. Obviously, to be caught driving a vehicle which you know to be unsafe will be a much more serious offence that not having a valid MoT and the Police have access to the test failure information. Not having a valid MoT is a FPN with no points.
I agree with Clive's post 100%. Cars with safety related problems should not be driven on the road.
