Safety And Your Vehicle

The “Safety and Your Vehicle” section of the UK theory test focuses on how to keep your vehicle roadworthy, environmentally friendly, and safe for use.

It covers essential checks such as tyre pressure, tread depth, fluid levels, and the condition of lights and brakes. You’ll need to understand how poor maintenance can affect performance and increase risks—like reduced braking efficiency or tyre blowouts.

This topic also includes awareness of emissions, fuel economy, and the importance of regular servicing. Ensuring your vehicle is properly maintained not only helps prevent breakdowns but also supports safer driving and compliance with legal standards.
