MOT Checklist - What to Check Before Your MOT If you own a used automobile approaching its MOT renewal date, you're undoubtedly concerned about the repairs that will be required to get it through another year of driving. However, there are several tests you can perform yourself to help save money and boost the probability that your automobile will pass its MOT test the first time. If you are planning for the MOT test, book your cheapest suzuki MOT online. Number plate Your automobile will fail its MOT if your registration number is not plainly visible. If the present plates are damaged or the font and spacing of the numbers and letters do not satisfy the legal criteria, give it a brief wash before taking it to the test center. Tyres To be legally roadworthy, your tyres must have a tread depth of 1.6mm in a continuous band across the center three-quarters of the tyre. Any tyres with less than this will result in a MOT failure. Place a 20p coin in the tread and see whether it covers the outside band of the coin. If it does, your tread is deeper than the legal limit. If not, you must change your tyres before the MOT test. Lights and indicators Check that all of your car's lights are operating correctly. This includes headlights, brake lights, brake light indicators, warning lights, reversing lights, and even the lights above the license plates. Ask someone to assist you in checking the brake and reversing lights. It's worth replacing any that aren't working before the test. Windscreen and wipers Check your windscreen for cracks or chips and get it fixed or replaced if the damage is more than 10mm on the driver's side and 40mm or more everywhere else. If you have any windshield stickers, they may cause your automobile to fail if they hinder your visibility in any way. You should also check that your screen washer jets are operating properly and that the reservoir is filled with the proper mixture of water and screen wash. Check that the rubber on the wipers is still excellent and that they can clean your front and rear windscreens adequately. Fuel and engine oil Check that there is enough engine oil and petrol in the car to get it through the MOT. The engine must be driven constantly to verify exhaust emissions, and the test center may refuse you if there is insufficient gasoline to complete these tests or if the engine is short on oil. Seatbelts Check that all of the seatbelts are correctly clipped in and unclipped, and that they are tightly locked. Check that they retract completely and that there are no cuts or fraying.
