Vehicle Emissions: What are they and how are they measured under the new MOT Test?

As of May 20th 2018 the MOT test for vehicles in the UK changed – but what does that mean when it comes to emissions? Never fear, Trust My Garage is here with the answers!

What are emissions?

The Department for Transport (DfT) states that emissions are pollutants created by petrol, diesel and alternatively-fuelled engines. These pollutants are; carbon monoxide, oxides of nitrogen, un-burnt hydrocarbons and particulate matter. The levels of pollutants present in each vehicle can depend on vehicle technology and the state of maintenance of the vehicle – so older cars have a tendency to produce more emissions.

 

Why do emissions matter?

Like all pollutants, they cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, which has been cited as a cause of global warming, acid rain, environmental damage and human health damage. Engine noise and fuel spills also cause pollution. Nitrous oxide emissions have also been shown to contribute to the depletion of the Ozone layer around the Earth.

 

How is the new MOT test combatting emissions?

The MOT test now includes updates for the amount of emissions a diesel vehicle can produce – with garages also having to update their Diesel Smoke Meters to ensure they meet requirements for testing. Find out what the .Gov website states about emissions testing here.

 

As well as this, if your car is new enough to have a Diesel Particulate Filter (DPF), evidence that it has been tampered with – or the presence of exhaust smoke of any colour – will now constitute a ‘major’ MOT fault. This will need to be rectified before a pass can be issued.

What else is being done to help?

Over time, vehicle manufacturers have realised the importance of emissions and pollution for the environment. The ‘Euro 6’ emission standard has provided a benchmark form of legislation, and as of September 2015 all mass-produced cars sold from this date need to meet the set requirements. The aim of Euro 6 is to reduce levels of harmful car and van exhaust emissions, both in petrol and diesel cars.

 

Emissions of air quality pollutants from road vehicles have been reduced by improving the quality of fuels and by setting increasingly stringent emission limits for new vehicles. As an example, it would take 50 new cars to produce the same quantity of air quality pollutant emissions per kilometre as a vehicle made in 1970.

 

How can motorists help?

When you’re driving you may not think about the impact your vehicle could be having on the environment – but if you’re concerned about reducing the effects of pollution, there are some very simple tips to utilise:

Drive Steadily – hard acceleration and braking forces your vehicle to work harder, creating more emissions from your exhaust.

Don’t overload – the additional weight will require you to use extra power. This means that your engine is using more fuel to accommodate the extra kilos.

Have regular services – By keeping your vehicle well maintained you can ensure all its internal parts are working efficiently, putting less stress on your motor and the environment! Don’t forget, you can book a service and find your nearest Trust My Garage member here with our ‘Find a Garage’ map.

Stretch your legs – if you feel comfortable walking or cycling, then do so! Leaving your vehicle at home means it definitely can’t emit any pollutants.

What to do when… Your motor needs an MOT

The MOT is a mandatory annual requirement for vehicles in the UK – but how do you go about organising yours, and how does it benefit your vehicle?

 

If you’re feeling a little bit lost when it comes to the process, Trust My Garage has put together some top tips and advice on how to ensure you’re meeting the legal requirements and giving your motor some TLC at the same time.

 

While this information is currently up to date, the MOT test will change on 20th May 2018. Some new things will be included, defects will be categorised differently, there will be stricter rules for car emissions and diesel vehicles, and some vehicles over 40 years old won’t need an MOT. Look out for our blog post detailing the changes coming soon.

 

How do I know when my MOT is due?

Your car must undertake its first MOT three years after its first registration, and then every year after that. If you need to know when your MOT is due, you can sign up to the new .GOV MOT reminder service. This will provide you with a reminder one month before your MOT is due. You’ll get another reminder if you still haven’t had your vehicle tested 2 weeks before your MOT is due.

 

Ok, I know when my MOT needs to be completed – now what?

You can take your vehicle to any registered MOT testing station that provides tests on your class of vehicle. If you have a car, this will be Classes 4 & 7 and for motorcycles it’s Classes 1 & 2. MOT stations should have a sign outside that looks like this:

This sign shows that the station has been approved by the DVSA as fit to carry out MOT tests, and you will be able to take your vehicle there to have the test completed.

 

How do I find an MOT Testing Station near me?

With over 22,000 MOT Stations operating in Great Britain, there’s plenty of choice to be had! If you’re looking for a trusted independent garage near to you, most Trust My Garage members are approved MOT stations. You can use TMG’s handy Find a Garage map to locate a garage that adheres to a Chartered Trading Standards (CTSI)-approved code of conduct. The Trust My Garage shield acts as a badge of quality for the independent garage sector, and demonstrates the commitment our garages follow to provide the highest levels of workmanship and customer service.

 

So, I’ve had my vehicle MOT’ed, but how does it help?

The MOT covers many aspects of vehicle safety and roadworthiness, as well as conducting compulsory exhaust emissions tests. At the end of the test, you will receive a certificate proving your vehicle has passed or details on why your vehicle has failed, as well as an advisory information provided by the qualified MOT Tester. Have a look at the photo below to see the areas covered in the test for cars:

For a more in-depth breakdown of all the parts of your car looked at during the MOT, you can have a look at the full government list here.

 

Right. I’ve had a service though, is that the same thing?

Simply put, no. The MOT does not cover the condition of the engine, clutch or gearbox, which are the parts of your car that will be looked at during a service. A yearly service is also NOT mandatory, but is strongly recommended to help keep your vehicle in roadworthy condition. Many motorists opt to have their MOT and service conducted at the same time, as it means any issues can be detected and rectified in one appointment.

 

But my car looks fine, so why would it even need an MOT?

While it’s true that your car may look fine at a glance, when was the last time you checked the tread on your tyres? Do you know the proper depth it needs to be at to be road safe? Do you think your brakes are as responsive as when you first got your car? Are the electrics still safe and functioning properly? The MOT is designed to ensure your vehicle is as safe as possible when you drive it, and lets you know if there are any problems before they become a real danger to you and other road users.

 

Thanks! Remind me, where can I get my vehicle MOT’ed again?

No problem – you can take your vehicle to your nearest Trust My Garage member business. Whether it’s for an MOT, check-up, service or repair, the Chartered Trading Standards Institute (CTSI) approved code of conduct that our members use mean that you and you motor both get the best possible service.
