The examiner's written questions mirror the 'show me, tell me' checks: tread depth, tyre pressures, fluid levels, warning lamps and what a particular dashboard colour means. Environmental questions sit here too — smooth acceleration, avoiding unnecessary idling, and why harsh braking costs both fuel and brake life. Once you're passing this topic comfortably, try a [full mock test](/theory/mock-test) under real timed conditions, brush up on [UK road signs](/theory/road-signs), or browse the [full question bank](/theory/questions). Ready to drive? See our [intensive driving courses](/courses). ## Safety and your Vehicle Question 1 of 76 ### A vehicle MOT test will include an exhaust emissions test. What is the reason for this? A To see which fuel supplier is the most popular B To cover the cost of garage equipment C To ensure diesel and petrol engines give off the same fumes D To help protect the environment Previous ## What the DVSA tests on safety and your vehicle - Legal minimum tread depth of 1.6mm across the central three-quarters - Dashboard warning lamp colours and which mean stop immediately - Braking, steering and suspension faults and how they feel - Fuel economy, emissions and eco-safe driving technique - Security, parking safely and where to leave a vehicle overnight ## Common mistakes in this topic - Quoting 1.6mm as an all-weather safe depth rather than the legal minimum - Checking tyre pressures when the tyres are hot instead of cold - Treating an amber warning lamp as something to ignore - Forgetting that an over-inflated tyre wears in the centre, not the edges **Instructor tip:** Learn the warning lamp colours as a traffic-light system: red stop, amber investigate, green or blue informational. ## Passed your theory? Get the practical booked Your theory certificate lasts two years. Most learners who use it quickly do it with an intensive course — a block of hours with a DVSA approved instructor and a practical test at the end, instead of one lesson a week for months.
