Motorists are being urged to check their tyres and brakes more regularly as these faults were behind 2.1 million 'dangerous' MOT failures.
DVSA data analysed by the RAC found that a third of all initial MOT tests of cars, vans and small passenger vehicles - the equivalent to 7.3m vehicles - resulted in a fail in the 12 months leading up to March 2022. This meant millions of drivers had to fork out for remedial repair work.
Lamps, reflectors and indicators continue to be the most frequent reasons for failure, but it was the more serious problems with brakes and tyres which the motoring group is concerned about.
