What you need to know about the MOT test changes
Diesel drivers have been advised that their vehicles will face stricter emissions tests from 20 May 2018, as well as new categories that are being introduced to ensure maximum safety and economy. Following much recent media coverage on the true cleanliness of diesel vehicles and the safety of British roads, the proposed changes have been welcomed by many motorists. So, what are these new rules and how do they affect drivers?
A stricter smoke test
Cars and vans emitting clouds of black smoke will no longer be a sight on British roads when the new rules come into play. Such vehicles are releasing a harmful level of pollution due to faulty diesel particulate filters, which when working inefficiently can increase particulate counts by up to 20 times.
Since 2014, MOT testers have been required to ensure the original DPF is in place as some motorists were removing them, but now they will be tested for functionality as well. As a result, if the diesel has a DPF that emits smoke of any colour, it will automatically fail the MOT. In addition, if the canister is found to have been cut open and re-sealed, the vehicle may be refused a test unless its owner can prove the damage was caused by legitimate filter cleaning.
