Our mock theory test allows you to practice your category 'B' (Car) theory test. We cover the five core areas that you will be tested on:

Control of the Vehicle
Legal Matters / Rules of the Road
Managing Risk
Safe and Socially Responsible Driving
Technical Matters

You have forty-five minutes to answer forty questions and must answer at least thirty-five correctly to pass.
