Most cars on British roads have their emissions tested in order to gain an MOT certificate. Only models that are under three years of age or that are exempt from the MOT system – such as certain vintage models – won’t need to undergo this crucial test. What is it and why is it done? Read on to find out.
What Is an MOT Emissions Test?
To begin with, emissions testing is only a part of the MOT which involves numerous other checks, such as inspecting the brakes, seatbelts and electrical systems of a car. For an emissions test, the car’s engine is run and then the MOT technician will use a meter close to the exhaust of the vehicle to confirm the particulates being released fall within the government’s threshold. Older vehicles won’t always produce emissions in a way that allows a meter to provide accurate results. Consequently, petrol cars made before 1975 and diesel ones manufactured before 1980 usually undergo a visual emissions test instead.
It is worth noting that electric vehicles over three years of age also need to have an MOT. However, since all-electric vehicles don’t produce local emissions, this part of the test won’t have to be carried out. That said, all hybrid vehicles have to have the same emissions test conducted as a part of their MOT. So, for expert MOT facilities, choose KAP Brighton MOT Testing Service for your upcoming due date. Remember that you can book an MOT in the month before your next one is due without bringing forward the date of the subsequent one. Therefore, there’s no need to wait until your current one has almost expired.
Why Are Car Emissions Tested?
Car emissions are a public health problem. The main reason that they were first introduced was to help people who live near busy roads to enjoy cleaner, fresher air. Although you can see some gases escaping from the exhaust of a car, especially on a chilly day, many of the most poisonous and noxious gases that they release are completely invisible. This means that the only way to tell whether a car is producing acceptably low levels of emissions is to test for them.
By having vehicle emissions tested, it helps motorists to contribute to a cleaner, greener environment. Note that motorcycles and vans both have their emissions, tested, too, so it is not just car drivers who need to have this important check carried out with each MOT.
