An analysis of data from the Driver & Vehicle Standards Agency has revealed the most common reasons for MOT failures.

Price comparison website analysed over 19 million MOT records from the DVSA in 2016 to identify the reasons for failures.  It found that faulty lamps, reflectors and electrical equipment were responsible for more than one in four of all failures, while suspension accounted for 18% and faulty brakes for 15%.

Reason for Rejection                                                    Percentage of Fails

1.       Lamps, reflectors and electrical equipment                           27.6%

2.       Suspension                                                                           18.4%

3.       Brakes                                                                                   15.0%

4.       Driver's view of the road                                                        10.6%

5.       Tyres                                                                                      1.4%

6.       Exhaust, fuel and emissions                                                  6.1%

7.       Steering                                                                                  4.1%

8.       Seatbelts and restraint systems                                             2.9%

9.       Body structure and general items                                           2.2%

10.    Registration plates and VINs                                                  1.1%

“Motorists could be saving hundreds of pounds if they make simple vehicle checks before an MOT, to spot any faults,” the company’s MD Scott Hamilton said.  “Most of the most common faults can be picked up by a simple walk-around inspection of the car and can improve the chance of passing first time.  For example, many vehicles have inexpensive headlight and brake light bulbs that are easy to replace.  On the other hand, if faulty lights cause a vehicle to fail and the bulb is out of stock, it could mean the vehicle is not road legal for a day or two more.”
