The MOT test could be toughened up to ensure car owners are submitting to vehicle safety recalls.
The Driver and Vehicle Standards Agency (DVSA), which oversees safety recalls, is reportedly planning to work with the Department for Transport to determine how the roadworthiness test could be adjusted to cover outstanding recalls.
Recalls are a common part of the car industry, with manufacturers issuing them if a fault is detected which is deemed to pose a potential safety risk. They can cover everything from a poorly fitted sunroof or faulty seat belt buckle to engines cutting out and fire hazards.
Under the current system, manufacturers use DVLA data to inform the registered keeper of a car of any recalls to that model. It is then up to the keeper to have the remedial work carried out but there is no legal obligation and an estimate 2.38 million cars in the UK are currently subject to an outstanding recall.
Neil Barlow, the DVSAâ€™s head of vehicle engineering, told Auto Express: â€œit would make logical sense where appropriate for the MOT to be aligned with the safety recalls systemâ€ to ensure all cars have the work carried out.
He said the DVSA intended to â€œwork with the Department for Transport to determine how the MoT system can be adjusted to cover outstanding safety recalls in the futureâ€.
Mr Barlow added that any such alignment of systems would need to give drivers reasonable time to have recall work carried out – to ensure they werenâ€™t penalised for a recall issued just before their carâ€™s MOT.
It is thought the agencies could follow the example of Germany where owners are given a warning if their car has an outstanding recall when tested under its equivalent of the MOT. If the recall hasnâ€™t been addressed by the time of the next test the car will fail.
Mr Barlow said that if such changes were to be introduced they would require changes to legislation.
The DVSA launched an online tool last year allowing owners to check if there are any outstanding recalls against their car.
