Once your MINI is three years old, you’ll need a valid MOT test certificate, which then needs renewing annually. You can do this a month (minus a day) before the expiry of your existing certificate, without ‘losing’ the number of valid days on the certificate.
Clearly, this test highlights obvious performance and safety issues with a vehicle. But not having a valid MOT also means you would be driving unlawfully, and wouldn’t be able to renew your road tax. The fine for driving without a valid certificate is a maximum £1,000 penalty.
If you have an accident, any insurance claim could be affected if you’re unable to present a current MOT. What’s more, police patrols and mobile camera units are now able to check for certification remotely.
