IAM Motoring Trust research acquired through the Freedom of Information Act reveals that 21.6 per cent of three-year old cars fail their first MoT test (see note 1) – a higher failure rate than in some European countries that do first roadworthiness tests after four years (the European minimum).

HIGH FAILURE

"The high UK failure rates may argue against relaxing our MoT testing regime from three to four years on road-safety grounds.

But do we have the full picture?" said Neil Greig, IAM Trust Director.

"A Treasury-sponsored review in 2006 (see note 2) suggested that the UK practice of 'gold plating' the European minimum for roadworthiness testing was costing motorists £465 million a year.

As a result, the Department for Transport prepared a consultation that was due out in the summer of 2007 but has not appeared. In the meantime, motorists have seen no action and may have incurred nearly £1bn in costs for the current MoT testing system.

Who can blame them for worrying about being ripped off?" A 2007 IAM Trust survey (see note 3) showed that motorists viewed the MoT test as an essential road safety measure but that they suspected that failures were influenced by a garage's wish to carry out unnecessary work.

"It's time for government to get MoT testing out of the 'all too difficult' box; motorists have waited too long for answers to important questions," said Greig.

THE KEY QUESTIONS ARE;

·Why are first-test pass rates in some European countries better at four years than UK pass rates after three years?

·Does the three-year UK MoT test unnecessarily "gold plate" the European minimum requirement for roadworthiness – at a cost to UK motorists of £465 million a year?

·Would the application of European minimum standards be enough to guarantee roadworthiness of UK cars?

· Is there any evidence that accidents due to vehicle failure are greater in countries that wait four years for a first compulsory roadworthiness test?

· In the UK, only garages can carry out tests and supply the parts and labour needed to rectify faults.

In some European countries, testing and rectifying procedures are separated - should we consider the introduction of independent testing centres?

Greig also questioned why so many UK cars fail the first MoT test after just three years when three-year warranties and service agreements are common. "Is it because garages do the MoT test before the three-year warranty service instead of after it, which fuels motorists' suspicion that the MoT is being used to show that the service has been done properly?

Do manufacturers' service schedules not cover all the points needed to pass a MoT test – if not, why?"

AND FINALLY:

"Are high failure rates down to motorists failing to maintain their cars properly?"

In the 2007, 21.6 per cent (580,754) of three-year old cars failed the first MOT test they went through.
