Owning an older car can be rewarding as they're often reliable, familiar and sometimes even more comfortable to drive than a newer model. But when your car reaches 15 years old, the annual MOT test can feel like a major hurdle. The test is designed to keep all vehicles on the road safe and roadworthy, but as cars age, wear and tear makes passing a little trickier. Fortunately, with the right preparation, even a 15-year-old car has a good chance of passing first time. This guide will give you straightforward advice and some old car MOT pass tips to help your car get through the test.
When Does a Car Need an MOT?
In England, Scotland and Wales, all cars need their first MOT once they reach three years old. In Northern Ireland, it's after four years. From then on, an MOT is required every year. Your MOT certificate will always show the expiry date, so you know when the next test is due. You can even book your MOT up to a month (minus a day) before the certificate runs out and still keep the same renewal date. You can find your local Protyre garage to book your MOT by using our garage finder tool.
MOT Prep for Older Cars
Older vehicles often need more attention to pass, but there are plenty of simple checks you can do at home before taking it in. Think of this as your pre-MOT checklist:
Clean your car - inside and out. An examiner can refuse to test a filthy car.
Number plates - wipe them down so they're easy to read.
Lights - check every bulb works. Ask someone to stand outside while you try the indicators, brake lights and fog lights.
Tyres - use the 20p test to check tread depth. Tyres should have at least 1.6 mm of tread across the central three-quarters. Don't forget to check the pressure too.
Wipers and windscreen - wipers should be free of tears, and the screen should be free of cracks or chips.
Mirrors - make sure all are intact and secure.
Fluids - top up screen wash, oil, and brake fluid.
Horn - give it a quick honk. It must work and be loud enough.
Spending half an hour on these basics could be the difference between a pass and a fail.
What the Tester Will Check
When your car is up on the ramp or rollers, the MOT inspector will look at several areas:
Brakes - efficiency, balance, and overall condition of pads, discs and brake lines.
Suspension - springs, shock absorbers and joints for wear or corrosion.
Bodywork - sharp edges or excessive rust near important components are not allowed.
Exhaust and emissions - smoke, leaks, or too much noise can cause failure.
Steering - the wheel, column and joints must be secure with no excessive play.
Seats and seat belts - they must be firmly fixed and in good condition.
Windows and mirrors - vision must not be impaired by cracks, damage or loose fittings.
Wheels and tyres - secure, free from damage, and fitted correctly.
For an older car, rust is often the most worrying area. If corrosion is within 30cm of key components such as the steering or suspension, it could mean a fail.
What if Your Car Fails?
If your 15-year-old car doesn't pass, don't panic. You'll be given a VT30 'refusal of MOT' certificate, which lists the faults. Failures are graded as:
Dangerous - must be repaired before you drive again.
Major - should be repaired as soon as possible.
Minor - you can still pass, but repairs are advised.
If repairs are done within 10 days at the same garage, you can usually get a free partial retest. This makes it worth asking the garage to fix small problems straight away.
After the MOT
Passing is the best outcome, but even if your car comes back with advisories, don't ignore them. They're early warnings that something will need attention soon, such as tyres nearing the tread limit or brake pads starting to wear. Deal with these in good time, and your next MOT should be much less stressful. If you need new tyres, at Protyre we stock tyres from manufacturers including Sumitomo and Bridgestone. You can match your car to your new tyres by using our tyre finder tool.
Frequently Asked Questions
Yes, older cars are more prone to rust, worn suspension and emissions issues. However, with regular servicing and proper MOT preparation, many older cars still pass first time.
You can, but it will usually reduce its value significantly. Most buyers prefer a car with at least six months' MOT. Without one, you can only sell it as a 'spares or repair' vehicle unless the buyer arranges their own MOT immediately.
