If
the vehicle is presented for test within the calendar month
prior to the date that the MOT is due, the test certificate
will run from the date of the test to one year after the expiry
date of the current certificate for example if the current
certificate was due to expire on 1 April 2003, and the vehicle
was presented on or after 2 March 2003, the certificate would
run from the test date until 1 April 2004.
To
have this extension, the vehicle owner should present their
old certificate to the test station to verify that the extra
time is applicable. The tester would then write the serial
number of the old certificate in the appropriate section of
the new certificate.
The
same rule would also apply if the vehicle was taken in within
a calendar month of its first MOT. In this case, the vehicle
owner would need to present their registration document and
the serial number from this document will be entered in the
'last certificate serial number' box on the MOT.
If
the vehicle is tested earlier than one month before it's due
date, it will only run for twelve months.
