The MOT Test is an annual test of roadworthiness for motor vehicles in the United Kingdom. It is a legal requirement for all cars over three years old to have a valid MOT certificate, and failure to do so can result in a fine and even disqualification from driving.
The test checks that your vehicle meets the minimum safety standards required by law, and it is your responsibility as the owner to make sure that it does.
However, there are some things that you may not be aware of which could lead to your car failing its MOT. In this article, we will take a look at some of the most common reasons for failure, and what you can do to avoid them.
1. Tyres
One of the most common reasons for failure is incorrect tyre pressure. The minimum legal tread depth is 1.6mm, and any tyres with a tread depth of less than this will get marked as an advisory item. However, it is advisable to replace tyres before they reach this point, as they will be more vulnerable to punctures and could pose a danger to other road users.
It is also worth noting that the tyre pressure listed on the side of your tyres is the maximum pressure, not the recommended pressure. You can usually find the recommended pressure in your car's handbook, or on a sticker inside the driver's door or you can get it checked when you are getting Car Repair Bolton done.
2. Lights
Another common reason for failure is faulty lights. Headlights, brake lights and indicators must all be in working order, and any bulbs that have blown must get replaced. It is also important to make sure that all lights are clean and free from debris, as this can affect their visibility.
If your car has Xenon headlights, you will need to have them checked by an authorised dealer every two years.
3. Mirrors
Mirrors must be free from cracks and chips and must be securely attached to the car.
4. Windscreen
The windscreen must be free from cracks and chips, and any damage that obscures the driver's view of the road will result in an immediate failure.
5. Suspension
The suspension system must be free from excessive wear and tear, and all components must be securely attached to the vehicle.
6. Brakes
The brakes must be in good working order, and there should be no leaks in the hydraulic system. The handbrake must be able to hold the car on a steep hill, and all brake pads and discs must meet the minimum legal standards.
7. Emissions
All cars must meet the minimum emission standards for their fuel type. petrol cars must not exceed 0.08% carbon monoxide or 0.5% hydrocarbons, while diesel cars must not exceed 0.3% carbon monoxide or 0.25% particulates.
8. Exhaust
The exhaust system must be in good working order, and there should be no leaks or major corrosion. The catalytic converter must also meet the minimum requirements, and any modifications to the exhaust which make it louder than standard will fail.
9. Bodywork
Any major damage to the bodywork, such as rust holes or dents, will fail. However, small scratches and chips will not necessarily cause a failure, as long as they do not obscure the driver's view of the road.
10. Seatbelts
All seatbelts must be in good working order, and all occupants of the car must wear them when travelling on a public road.
11. Safety Devices
Any safety devices which get fitted to the car, such as airbags and child seats, must be in good working order.
12. Fuel System
The fuel system must be free from leaks, and there should be no vapour escaping from the fuel cap.
