The number of failed MOT tests has doubled since the past year. Figures from the Driver and Vehicle Standards Agency show that the stringent new measures on emissions have made the tests tougher for all cars.
Diesel vans have the highest rate of MOT test failures. In 2018, there have been a total of 19,648 failed MOT tests so far. Compared to the reports from 2017, when about 3,585 diesel vans failed the MOT tests, the difference is significant. Regarding other cars that run on petrol, the reports indicate that an estimated 505,721 have failed the MOT tests.
Let’s have a look at what has changed:
It is obvious the UK authorities are serious about eliminating dangerous emission from all vehicles. The new measures added to the previous MOT tests now require all vehicles to have untraceable emission levels. This effort will go a long way in protecting the environment and our lives.
The new standards for MOT tests were introduced on May 20, 2018. The main focus is to compel all vehicle owners and business owners to ensure their vehicles have zero emission levels to pass the MOT tests.
The rule changes responsible for the majority of the MOT test failures is the emission checks from the vehicle’s exhaust. The test, in this case, is done to confirm no smoke, of any colour, emits from the exhaust while the engine is running. To pass this test, the vehicle’s engine must be in an excellent condition.
Other tests that have rendered the diesel vans unfit for the roads in the UK include the tests to ensure the Diesel Particulate Filter (DPF) is in perfect condition. The DPF is responsible for preventing harmful emissions from release into the atmosphere. In newer vehicles, this device works perfectly, but its functions can be compromised over the years. If the DPF malfunctions, its ability to reduce harmful emissions will be lowered. The mechanics will observe this defect. Subsequently, a failed MOT report is issued.
Other tests that have been highlighted in the new MOT standards include checks for leaks, faulty brake pads, inflated tyres, and the functionality of all signal lights among other mechanical tests.
While the tests may seem ‘unfriendly,’ the big picture looks good. The new standards compel all road users to maintain their cars to pass the tests. Also, vehicles that fail the tests must be repaired to meet the new MOT standards. What’s more, the changes have not influenced the price for MOT tests which remains £54.85 under normal circumstances.
