The theory test is made up of a multiple choice part and a hazard perception part. You need to pass both parts to pass it. Once you have passed the theory test you can then apply to take your practical riding test. The multiple-choice part is delivered using a touch screen computer and the hazard perception part records your responses through the use of a computer mouse button. If you pass one part and fail the other you’ll fail the whole test, and you’ll need to take both parts again.
