Clocking up the mileage

Posted by: , Posted on: - Categories: News and updates

As of 18 November 2012, MOT certificates - VT20s - show the mileage of the vehicle for the last three VT20 certificates issued, along with the mileage for the current test.

Having this information on the MOT certificate helps to prevent the crime of ‘clocking’ so it is important that testers record the mileage accurately from the vehicle’s odometer.

If you enter the mileage incorrectly, don’t worry - you can issue a replacement certificate if it’s within seven days of the test. Appendix 10.I2 of the VTS Device User Guide tells you how to do this. Press F5 on the VTS Device to bring up the Guide.

The issuing VTS can only correct a mistake in the vehicle’s colour or current test mileage. Any other changes should be made through your local VOSA Area Office.
