The AA has warned cars could become “death traps on wheels” if annual MOT tests are changed to every two years.

Under new plans the time between MOT tests could increase from one year to two years, and from three years for a new car needing its first MOT to four years.

The Department for Transport (DfT) said it has launched a consultation on the proposals, hoping to cut costs for drivers.

The DfT said it wants to “ensure roadworthiness checks continue to balance costs on motorists while ensuring road safety, keeping up with advances in vehicle technology, and tackling vehicle emissions”.

Drivers can be fined up to £1,000 for using a vehicle without a valid MOT.

The tests check a number of parts such as lights, seatbelts, tyres and brakes to ensure they meet legal standards.

The DfT said MOTs cost an average of £40 and delaying the first test for new vehicles could save motorists around £100 million a year.

It said “major developments in vehicle technology” have increased road safety since MOTs were introduced in 1960, such as lane-assisted driving.

However, Edmund King, president of the AA, said the organisation was “totally opposed” to the changes, also telling This is Money the change would see “an increase of death traps on wheels on the road”.

He said: “The MOT plays a vital role in ensuring that vehicles on our roads are safe and well maintained, and while not a formal recommendation, we totally oppose any change from an annual MOT.

“Last year, 83% of drivers said that the annual MOT was ‘very important’ for keeping our cars and roads as safe as possible, which highlights why an annual MOT must remain in place.

“With one in 10 cars failing their first MOT, we strongly discourage the Government from extending a car’s first MOT to the fourth anniversary due to road safety concerns.”

The RAC’s head of roads policy Nicholas Lyes said: “While we’re not opposed to delaying a new vehicle’s first MOT, we believe there should be a requirement for particularly high mileage vehicles to be tested sooner.

“If the Government is looking to improve the MOT, now is the ideal time to take into account how much a vehicle is driven alongside the number of years it’s been on the road.

“We’re also disappointed the Government is still entertaining the idea of increasing the time between MOTs.

“Our research clearly shows drivers don’t agree with this and believe it’s dangerous.”
