Changes have been made to the current roadworthiness directive by the Government, which will affect MOT testing and procedures for vehicles across the U.K, arguably making them tougher.
Roads Minister Jesse Norman, announced the decision of the changes earlier this year and said:
"We have some of the safest roads in the world, and are always looking at ways of making them safer. Although modern cars are better built and safer than when the MOT test was last changed 50 years ago, there has been a clear public concern that any further changes don't put people's lives at risk."
The MOT changes came in to effect on 20 May 2018 and developments have been made to the current Driving and Vehicle Standards Agency (DVSA) regulations in an attempt to tackle emissions by tightening the rules.
Diesel powered vehicles will mostly be affected by the changes, meaning around half of the U. K's motorists. MOT testers have been advised to check diesel particulate filters (DPF) - a component designed to reduce pollution levels. Those that have been tampered with or removed, or vehicles emitting any colour of smoke will face an instant fail.
