Head lights and indicators
Check that all of your car's lights function properly - headlights, sidelights, rear lights, hazard-lights and indicators.
Press the brake pedal and ask a friend to check that the rear brake lights come on - including any supplementary brake strip light. Alternatively, carefully reverse up to a reflective surface - (window, wall or garage door) and look behind to see for yourself.
Make sure that the number plate is clean and legible - even a quick wipe with a cloth can make a difference. The font and spacing of letters must also comply with legal requirements to be passed by the MOT station.
Wheels and tyres
Check that wheels and tyres are undamaged. The minimum legal tyre tread depth is 1.6mm and any tyres with less than this will be marked as an MOT fail (though it's recommended that tyres are changed when tread reaches 3mm). If you're in doubt about how much tread is left on a tyre, your local manufacturer main dealer can check for you. The dealer can also advise on the type of tyre that is right for your car if a replacement is required.
They save your life in a crash, but only if they work properly inspect the full length for damage and tug sharply on all the seatbelts to check that they react as they're supposed to if you have to brake severely.
Check the view out of the front of the car for damage any damage larger than 40mm will cause a fail, as will any damage wider than 10mm in the swept area of the windscreen in front of the driver.
Make sure your wipers are able to keep your windscreen clean, any tears or holes in the wiper rubber can be an MOT fail.
Top up the washer bottle before taking the car in for a test, something as simple as an empty container can cause an MOT fail.
Give a short blast of the horn, if it doesn't work, your dealer will need to repair or replace it.
Fuel and engine oil
Make sure your car is filled with enough fuel and engine oil, you can be turned away from the MOT without suitable levels of either, both of which are required by the tester when running the car to test its emissions levels. If you are unsure about the type of oil that should be used, ask us.
Note: When checking fluid levels and handling parts that could be become hot to the touch (e.g. bulbs), it's always best to ensure that the vehicle has had opportunity to cool down fully.
