Analysis of more than 400 million MOT records from the DVSA by consumer website HonestJohn.co.uk has shown that lamps, reflectors and electrical equipment is the biggest MOT failure with 4.5 million vehicles caught out each year.
Suspension problems have been highlighted as the second most-common cause of failure and has been recognised as one of the fastest growing MOT failure points.
The data was revealed following a Freedom of Information request by HonestJohn.co.uk.
Brakes accounted for 9.5 per cent of failures, condition of tyres have a 7.5 per cent failure rate and tyre tread depth was a failure item in 4.4 per cent of cases.
Driver’s view of the road has a 6.8 per cent failure rate, with worn wipers and windscreen cracks causing problems with the driver’s line of sight.
Another fast-growing MOT failure are position lamps, accounting for 1.2 million vehicles failing their annual roadworthiness test.
HonestJohn.co.uk believes it’s possibly a trend caused by manufacturers swapping traditional bulbs for sealed unit LED items.
