MOT Reports Bad Braking Dominant CV Issue


LONDON, U.K. – Brake failures continue to dominate the top 10 reasons for commercial vehicle MOT failures, with potentially serious road safety issues not being picked up by vehicle technicians.

The MOT is the annual test of vehicle safetyroadworthiness aspects and exhaust emissions required in the United Kingdom for vehicles three-years-old and older.

Figures provided by the Department of Transport’s latest annual MOT report show that commercial vehicle brake testing has improved significantly since 2013, but more is needed to be done.

The traffic commissioners (TC) who were responsible for the MOT said that in 2017/18 there were 10,000 fewer failures for service brake performance at annual tests than in 2013/14.

The biggest improvement has been for trailers, with an extra 5,500 passing their brake performance test first time.

However, the TCs said there were still 22,000 failures for service brake performance during the period.

Common issues include vehicles and trailers being brake tested unladen with wheels locking at very low brake efforts; printouts saying ‘pass’ when one or more brakes are not working properly and a lack of understanding that the standard to be applied at PMI inspection must be above the minimum MOT requirement.

The TCs also admitted that its target under a new measure of ‘average processing times’ for O-license applications had been “ambitious”, with an average of just over eight weeks to determine applications for HGV licenses against a target of seven weeks.

But it added that for operators using digital services and providing complete applications, it took less than 32 days on average to process applications.
