Mock Theory Test

Practice Your RSA Theory Test

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.

Want to brush up on just your road signs before your test? Try our Irish Road Sign test.

Good luck!
