2. Passwords and security

The Driver and Vehicle Standards Agency (DVSA) is aware that some MOT testers have shared their sign in details with third-party organisations.

Using your MOT user ID, password or security card number on other websites or software is a serious breach of security. DVSA takes this type of misuse very seriously.

Never share your login details with anyone or use them for any other purpose.

If you share your details you’ll breach the terms and conditions you signed and agreed to when you joined the service.

You can be suspended from MOT testing if you breach the MOT testing service terms and conditions.

3. Missing heat shields

Only fail a vehicle for missing heat shields if there’s a risk of fire with other fuel system components.
