An analysis of the latest data from the Driver and Vehicle Standards Agency (DVSA) has revealed the most common reasons for MOT failures., the UK’s leading price comparison site where service providers quote for MOT, has analysed over 19,400424 DVSA MOT records from 2016 to identify the reasons for failure for vehicles undergoing their MOT.

Faulty lamps, reflectors and electrical equipment were responsible for one in four of all MOT failures (27.6%), while suspension accounted for 18.4%, followed by faulty brakes, which resulted in 15% of failures.

After lights, brakes and suspension, ‘driver’s view of the road’ was the next biggest reason for MOT failure (10.6%) and one which can be easily fixed by motorists, prior to an MOT.  So often it’s down to large cracks in the windscreen, dashcams, stickers and other obstructions restricting the driver’s view.

Worn out tyres caused one in 10 cars to fail, while issues with emissions and fuel systems were responsible for another 6.1% of failures. Problems with steering caused 4.1% of failures, followed by seatbelts at 2.9%.

Scott Hamilton, Managing Director of comments: “Motorists could be saving hundreds of pounds if they make simple vehicle checks before an MOT, to spot any faults.  Our research shows that yet again, the main failure categories are lighting and signalling, including faults such as failed bulbs and misaligned headlights; brakes; tyre damage, as well as tyre wear; drivers view of the road, including windscreen damage, windscreen wiper faults, windscreen washer not working and missing, or faulty mirrors.

“Most of these faults can be picked up by a simple walk-around inspection of the car and can save money and improve the chance of the vehicle passing first time. For example, many vehicles have inexpensive headlight and breaking light bulbs that are easy to replace. However, if faulty lights cause a vehicle to fail an MOT and the bulb is out of stock, motorists could end up with a vehicle that is not road legal for a day or two.
