It is a criminal offence to record your driving test. Do not do it. The dvsa have reviewed their policy below.

DVSA has concluded its review of the policy on filming driving tests. The agency has decided to maintain its general policy of not allowing the recording of theory or practical tests.
However, cameras fitted for insurance purposes will be allowed providing they:
· are external facing and do not film the inside of the vehicle;

· do not record audio from the inside of the vehicle.
DVSA will under no circumstances accept, comment on, or review audio or video footage provided by a test candidate or third party to facilitate a challenge to the conduct of any theory or practical test or its result. Any footage received in connection with an allegation of criminal activity or intent will be referred to the police.
