When is my car's MOT due?

The MOT test is a mandatory annual check for vehicles in the UK that are three years old or older. It ensures that your vehicle meets the minimum safety and environmental standards required to be on the road. Failing to have a valid MOT certificate can result in fines and even prevent you from driving your car. This comprehensive guide will walk you through everything you need to know about the MOT test, from understanding its purpose to preparing your vehicle for its annual inspection.

What are the new UK lockdown rules?
The UK government will be relaxing the lockdown rules further from July 4, 2020, though with continued restrictions in place including social distancing. The new rules will affect English hotels, bed and breakfasts, pubs and restaurants, as well as theatres, cinemas and galleries.

What is an MOT Test and Why is it Important?

The MOT test, or Ministry of Transport test, is a legal requirement for most vehicles over three years old. Its primary purpose is to ensure that your car is safe to drive and that it complies with environmental regulations. The test covers a wide range of components, including brakes, steering, suspension, tyres, lights, and emissions. By identifying potential faults before they become serious, the MOT test plays a crucial role in preventing accidents and ensuring the safety of all road users.

Regularly passing your MOT means your vehicle is:

  • Roadworthy: All essential safety components are functioning correctly.
  • Environmentally Compliant: Emissions are within legal limits.
  • Legally Compliant: You avoid fines and potential prosecution.

What does an MOT test check?

The MOT test is a thorough examination of your vehicle's condition. Here's a breakdown of the key areas inspected:

1. Vehicle Structure

This includes checking for corrosion or damage to the bodywork, chassis, and suspension components. Any significant rust or structural weaknesses can lead to an MOT failure.

2. Fuel System

The fuel lines and pipes are inspected for leaks and secure connections. The fuel cap must also seal properly.

3. Doors and Mirrors

All doors must open and close correctly from both the inside and outside. The number and condition of mirrors are also checked.

4. Brakes

This is a critical safety component. The MOT tester will check the condition and performance of your braking system, including the brake pedal, brake fluid, brake lines, and the effectiveness of the brakes themselves.

5. Tyres

Tyres must have a minimum tread depth of 1.6mm across the central three-quarters of the breadth of the tread. They are also checked for damage, cuts, bulges, and correct inflation.

6. Lights

All lights, including headlights, taillights, brake lights, and indicators, must be working correctly and be the correct colour. The aim is to ensure your vehicle is visible and signals its intentions clearly.

7. Steering and Suspension

The steering wheel, steering column, power steering, and suspension components (like shock absorbers and springs) are all inspected for wear, damage, and proper functioning.

8. Windscreen and Wipers

The windscreen must be free from significant chips or cracks in the driver's line of sight. The windscreen wipers and washers must also function effectively to ensure clear visibility.

9. Horn

The horn must be working and appropriate for the vehicle type.

10. Seats

Seats must be securely fitted and adjustable.

11. Seatbelts

All seatbelts must be present, in good condition, and function correctly.

12. Exhaust Emissions

Your vehicle's emissions will be tested to ensure they meet the required standards for its age and fuel type. This is a crucial aspect of environmental compliance.

13. Registration Plates

The number plates must be securely attached, legible, and meet specific design and spacing requirements.

What happens if my car fails its MOT?

If your car fails its MOT, it will be issued with a 'Refusal of an MOT Test Certificate'. The report will detail the reasons for failure and any 'dangerous' or 'major' defects that need to be rectified. You cannot legally drive your car on the road if it has a dangerous defect. If your car has only minor defects, you can usually continue to drive it until the MOT expires, but you must get the issues repaired to pass a re-test.

Here's what you need to do:

  • Undertake Repairs: Arrange for the necessary repairs to be carried out by a qualified mechanic.
  • Re-test: You will need to present your vehicle for a re-test. If the repairs are done at the same test centre, you may be eligible for a partial re-test on specific items, which can sometimes be free of charge if left at the centre for repair.

How to prepare your car for its MOT

While you can't predict every detail of the MOT test, a few proactive steps can significantly increase your chances of passing:

Area to CheckWhat to look for
LightsAll bulbs working, correct colours, no cracks in lenses.
TyresTread depth above 1.6mm, no cuts or bulges, correct pressure.
WindscreenNo major chips or cracks in the driver's view.
Wipers & WashersEffective cleaning of the windscreen.
Brake FluidCorrect level and clean.
Oil LevelWithin the recommended range.
HornWorking correctly.
Number PlatesClean, legible, and securely fitted.

It's also a good idea to check your car's manual for specific maintenance recommendations. Regular servicing can help identify and fix potential MOT issues before they become a problem.

When is your MOT due?

You can find out when your car's MOT is due by checking your current MOT certificate. If you've lost it, you can also check your vehicle's MOT history online using your vehicle registration number on the UK government's official website. It's advisable to book your MOT test in advance to avoid any lapses in your certificate, especially if your car requires repairs.

Where can I get an MOT test?

MOT tests can only be carried out by authorised garages and testing centres. You can find an authorised MOT testing station by looking for the blue three-legged spiral symbol. Many garages offer MOT testing services, so it's worth shopping around for competitive prices and good service. Remember to choose an authorised provider to ensure the test is conducted correctly and is legally recognised.

How much does an MOT test cost?

The maximum prices for an MOT test are set by the government. For cars, the maximum fee is £54.85. However, many garages offer MOT tests for less than the maximum price, especially when booked in advance or as part of a service package. Always check the price when booking your appointment.

Can I drive my car after the MOT expires?

You can only drive your car after its MOT has expired if you are driving it to a pre-booked MOT test appointment. If your car fails its MOT and has a dangerous defect, you cannot drive it at all, even to a repair shop. In this case, you would need to have it transported by trailer or recovery vehicle.

FAQs about MOT Tests

Q1: Can I get an MOT test done early?

Yes, you can get an MOT test up to one month (minus one day) before your current MOT certificate expires. If you take it early, your new MOT expiry date will be one year from the original expiry date, meaning you won't lose out on time.

Q2: What's the difference between an MOT and a service?

An MOT is a legal safety and environmental check, whereas a service is a routine maintenance procedure. A service involves replacing parts like oil, filters, and spark plugs to keep your car running smoothly and prevent future problems. While a service can help prevent MOT failures, it doesn't guarantee a pass.

Q3: Do electric cars need an MOT?

Yes, electric cars that are three years old or older also require an MOT test. The test covers similar safety aspects to petrol and diesel cars, with specific checks related to electric vehicle components.

Q4: What if I miss my MOT?

If you miss your MOT expiry date, you risk being fined and your car may not be insured. It's essential to keep your MOT certificate up-to-date to avoid these penalties.

In conclusion, the MOT test is a vital part of maintaining your vehicle's roadworthiness and ensuring the safety of yourself and others. By understanding what the test entails and preparing your car accordingly, you can make the process smoother and help keep your vehicle in top condition. Regular checks and timely MOT bookings are key to a safe and legal driving experience.
