You can find a wide range of driving simulators. Simple home-use and online simulators can help teach the rules of the road and give theoretical information. More elaborate simulators have a driver's seat, steering wheel, gears, pedals and multiple screens to provide a panoramic view.
For beginners, especially those who are nervous or need extra practice, driving simulators can provide a safe way to learn basic road rules and build confidence. Simulators can also check a learner's knowledge of theory and fundamentals before real world training begins.
For experienced drivers, simulators can reinforce what they already know. They also provide an opportunity to try new types of vehicles in a simulated environment and to experience driving conditions, such as snow and ice, that the driver may not be used to.
