Code Mobile is a useful application for learning the Highway Code and practicing with your vehicle. With Code Mobile, you can easily test yourself on the road, and check how well you perform. This is the most complete application for learning the Code of the Road in your mobile phone. You can choose from three different modes: test, training, and monitoring. The test mode allows you to choose a topic, and receive immediate feedback on your performance. The training mode is similar to the test mode, but you can choose the number of errors and the number of attempts, and receive feedback only after performing the task. The monitoring mode allows you to check how many errors you made, and how many times you made the mistake.
