From 23rd January 2012 the DSA is making changes to the UK driving theory test. From this date onwards, the DSA will add new multiple choice theory test questions to the test. The DSA will not allow anyone to publish these new theory test questions so they will not appear in any product or on any website. However, the DSA will continue to release official DSA theory test revision questions. The hazard perception part of the test will not change at all, nor will the structure of the theory test. For car drivers there will still be 50 multiple choice theory test questions, including 5 case studies and then the hazard perception part which consists of 14 video clips.
