Anybody learning to drive needs to take a theory test. This is a test you do that doesn’t involve sitting in the car at all, but instead shows you know the theoretical rules of driving. You may want to take this assessment before beginning practical lessons, as there is a possibility, with some cases, that you find it isn’t possible to drive once you begin lessons.
If you suffer from deafness or hearing problems, you can get a DVD about learning the Highway Code with sign language. There are similar products available to assist with the theory test, too.
