MOT Testing can feel like nothing more than a chore you have to do every year. But it has a lot to do with your car’s safety and legality on the road. If your car is more than 3 years old, it’s a legal requirement that you have an MOT test every year. But what exactly is included as part of an MOT, and how can you ensure your vehicle passes the first time around?
Here’s a helpful guide that explains all that goes on in MOT Testing and how you can quickly prepare your car.
What is MOT testing?
The MOT test is a mandatory check that your car needs to be put through to ensure that it conforms to all the legal requirements of road use. It doesn’t assess your engine, clutch or gearbox condition, but it inspects components related to how your car performs on the road safely and efficiently.
It’s the equivalent of the health check for your car. It’s not the same as a car ‘service’ but both are equally important. MOT Testing focuses on specific safety checks while ‘servicing’ covers wear and tear on moving parts.
When do you need MOT testing?
If your car is brand new, you won’t need MOT Testing until it’s three years old. After that, you’ll need to get your vehicle tested once every 12 months. Driving without a valid MOT can lead to fines, points on your licence, and even invalidate your insurance.
You can have your MOT Testing done up to a month before it expires and still keep the same renewal date. This gives you plenty of time to get any repairs done if needed.
What gets checked during MOT testing?
Here’s a breakdown of what the MOT Testing process involves:
1. Lights and signals
Your headlights, brake lights, indicators, and hazard lights must all be in working order. Even a single blown bulb can lead to a fail. Test them yourself before booking your MOT Testing—it only takes a few minutes.
2. Brakes
As a key safety feature, your car’s braking performance is thoroughly tested. This includes checking the brake pads, discs, and fluid. Any sign of severe wear or poor response can cause a failure.
3. Tyres and wheels
Tyres must have at least 1.6mm of tread across the central three-quarters of the tyre. They’ll also be inspected for any damage like bulges or cuts. Wheels must be secure and undamaged.
4. Suspension and steering
A worn suspension or loose steering components can affect your car’s handling. During MOT Testing, the tester will look for leaks, wear, or damage in these systems.
5. Exhaust and emissions
For petrol and diesel cars, emissions testing is a key part of MOT Testing. The exhaust must be securely fitted and not excessively noisy or smoky.
6. Windscreen and wipers
Any chips or cracks in the windscreen that obstruct your view will be noted. Wipers must clean the screen effectively and washer fluid must be topped up.
7. Seatbelts and seats
All seatbelts must work properly and retract fully. Seats must be secure and adjustable.
8. Mirrors
Your rearview and side mirrors must be secure, in good condition, and provide a clear view behind.
9. Horn
Your horn needs to work and be loud enough to alert other drivers.
10. Vehicle Identification
The tester will check the Vehicle Identification Number (VIN) and registration plates to see if they are clearly visible and compliant. Check out our MOT checklist for a comprehensive list of the MOT process.
Simple ways to prepare for MOT testing
Preparing your car for MOT Testing is simple. Here are a few things to prepare:
1) Check your lights
Get someone to help you test all external lights—front, rear, indicators, and number plate lights. Replace any faulty bulbs if you can or get an expert like BS3 Ltd to help you out.
2) Top up fluids
Make sure you’ve got enough screen wash, oil, and brake fluid. Low levels might not cause a fail, but it could lead to an advisory note.
3) Clean your car
It might sound trivial, but if your number plates are dirty or unreadable, you could fail the test. A clean car inside and out also helps the tester access areas more easily.
4) Check tyres
A useful trick is to use a 20p coin to check the tyre tread—if you can’t see the border, you’re likely fine. Look out for bulges or damage too.
5) Fix minor issues
If you’ve noticed squeaky brakes, a loose mirror, or worn wipers, it’s worth sorting these before your MOT Testing appointment.
What if your car fails MOT testing?
If your car fails MOT Testing, you’ll be given a refusal certificate (VT30). You can’t legally drive the car unless it’s for repairs or to a pre-booked MOT retest. Most garages will offer repairs and do a partial retest at a reduced rate or for free. Act quickly on any issues to avoid getting stuck without a vehicle unnecessarily.
How often should you get MOT testing?
By law, MOT Testing is an annual requirement. But if you drive regularly or your car is older, getting a service every 6 to 12 months alongside your MOT can help catch issues early—before they become costly repairs.
