Classic Car MOT Guide: Exemptions & Rules Explained
The
MOT rules for historic vehicles aren't the same as those for modern passenger
cars.
Classic cars benefit from certain exemptions, meaning their legal requirements differ from vehicles under 40 years old.
So what are the MOT rules for historic vehicles? And what makes them different to modern vehicles? Let’s explore the world of classic car MOTs.
Are Classic Cars Exempt From MOTs?
In the UK, classic cars become exempt from MOTs once the vehicle reaches 40 years old.
This 40 year MOT exemption is only granted if there has not been any “substantial changes” made to the vehicle in the past 30 years.
Such changes might include major modifications to the axles, running gear, or kit conversions.
It’s important to understand that this exemption does not apply universally to all vehicles over 40 years old.
Large goods vehicles (those with a maximum laden weight exceeding 3.5 tonnes) and commercial buses (defined as having eight or more seats) are not eligible for this MOT exemption, even if they are more than 40 years old.
These types of vehicles must continue to undergo regular testing due to their commercial use and operational requirements.
How to Apply for MOT & Road Tax Exemptions
As well as an MOT exemption, classic vehicles are eligible for a road tax exemption.
To apply for a road tax exemption, you must take the following to a Post Office that deals with vehicle tax:
- V5C in your name
- Vehicle tax reminder letter (V11) if you have one
- Evidence of your vehicle’s exemption from an MOT (V112)
- Evidence of a current MOT, such as a copy of your MOT history
Once you send for a road tax exemption, the Post Office will send your log book to the DVLA, who will then send you an updated log book.
In terms of an MOT exemption, you do not have to apply for one – once the vehicle turns 40 years old, the vehicle is exempt from needing an MOT unless there has been substantial changes made.
Classic Car MOT: Northern Ireland
If your classic car is registered in
Northern Ireland, the process for MOT exemption differs slightly from the rest of the UK.
While vehicles over 40 years old can still be eligible for exemption, you must apply directly to the Driver & Vehicle Agency (DVA) rather than relying on automatic exemption.
Historic vehicle owners will need to contact the DVA and submit supporting documentation to request exemption from testing.
This process includes proof of vehicle age and confirmation that the car has not undergone substantial changes.
If the exemption is approved, the DVA will update your vehicle record accordingly.
It's also worth noting that roadworthiness rules still apply in Northern Ireland, just as they do in the rest of the UK.
Even exempt vehicles must be kept in a safe and legal condition when used on public roads.
Can I Still Get an MOT for My Classic Car?
Yes – even if your vehicle is exempt from MOT testing, you’re still allowed to book one voluntarily.
Many classic car owners choose to do this for added peace of mind, especially if the vehicle is driven regularly or taken on longer journeys.
It also provides reassurance to potential buyers and insurance providers that the vehicle remains roadworthy.
Booking a voluntary MOT follows the same process as a standard test. You can arrange it through any garage that offers MOT services, and your vehicle will be tested against the usual MOT criteria.
Find MOT History
If you're unsure whether your vehicle has previously passed an MOT, or you want to check its testing record, you can look up its MOT history online.
GOV.UK MOT history tool allows you to view:
- Past test results
- Recorded mileage at each test
- Any advisory notices or failure reasons
This information is especially useful if you've recently bought a classic car or are planning to apply for exemption.
To check a vehicle’s history, all you need is its registration number.
Final Thoughts
Owning a classic car comes with unique responsibilities – and understanding MOT exemption rules is one of them.
While many vehicles over 40 years old no longer need annual testing, it’s still vital to keep them safe and roadworthy.
Whether you choose to apply for tax exemption, continue with voluntary MOTs, or simply want to explore the history of your vehicle, staying informed is key.
By following the correct processes and staying up to date with DVLA guidelines, you can keep your classic car both compliant and enjoyable to drive.
