Start with the road position you want to explore
Open the simulator and choose Start driving, or launch a lesson below. A browser with JavaScript and WebGL support is required; there is no app download. Keyboard and on-screen touch controls are available. A larger screen makes the road and mirrors easier to inspect.
Begin slowly and use small steering inputs. Switch between follow, cockpit, bonnet and aerial cameras to see how the same road position looks from different viewpoints. Your settings and lesson progress are stored locally in the browser on this device.
Choose one of the five existing lessons
- Find your left side: follow the left lane for 300 metres.
- Read the junction: stop for a red light and move through on green.
- Around the right way: explore a clockwise roundabout and signal left to exit.
- One way. More confidence.: follow the direction of a one-way street.
- Find your motorway rhythm: practise the left lane at motorway speeds.
Use free drive to revisit the roads between lessons. Optional coaching responds to your virtual driving, and settings let you adjust traffic density and graphics quality.
Learn a few controls, then focus on the road
Use W or the up arrow to accelerate, S or the down arrow to brake, and A/D or left/right arrows to steer. Q and E operate the indicators. C changes camera, M opens the map and R resets the car or current lesson. Hold Z or X to look left or right in cockpit or bonnet view.
On a touch device, use the steering and pedal controls on screen. Lower the graphics setting if performance makes positioning difficult. The complete practice guide and controls covers pausing, reversing and the suggested lesson sequence.
What this simulator can and cannot represent
Seabrook offers a place to explore the visual change to left-hand traffic and a right-hand-drive cockpit. Its traffic and physics are simplified. It is not an official course, licence test, validated driving assessment or evidence that you are ready for a real rental car.
The environment uses UK-style conventions. Selecting km/h does not load Irish, Australian, New Zealand or Japanese rules. The simulator also cannot teach the physical feel of a rental car, manual gear changes or every real-world hazard. See the simulator facts and limitations.
Connect a virtual session to your travel preparation
Follow the suggested pre-rental practice plan, then read the guide for your destination. Use its official links to learn local signs, documents and road layouts. At collection, still allow time to set the seat and mirrors and have the rental staff explain the actual controls.
