"the MoT Test"

This test is due on the 3rd anniversary of the bike's first registration and annually thereafter. It is an offence to use or keep the bike on the public highway without a valid MoT Certificate. You do not receive an automatic notification that the test is due, this is entirely your own responsibility.

As at 21st March 2004, the cost is fixed by the Government at £14.30. Athough test centres may give lower prices, they cannot charge more than this.

You may ride a bike without an MoT Certificate on the shortest route between where you live and the nearest test centre, provided that the test has been prebooked. You may also ride to the test centre to have the required repairs done.

You can apply for a test up to one month before the expiry of the previous Certificate. If the bike passes the MoT Test, the new certificate runs one year from the expiry of the old one.

You cannot apply for a Road Fund Licence ("tax disc") without a valid current MoT Certificate.

The MoT Certificate is not proof of a vehicle being either roadworthy or safe.

An examiner may declare a bike as being in a dangerous condition and prevent you from riding it.
