The theory test explained

What the test actually involves, what it costs, and the numbers you need to pass — all in one place.

The UK car theory test has two parts, taken back to back on a computer in a single sitting. You must pass both to pass overall.

Theory then practical — the fast track

Pass your practical in as little as a week

Once your theory's passed, Intensive Driving Courses Wales run 1-to-1 crash courses across South & West Wales, manual or automatic.

Part 1: multiple-choice questions

You answer 50 questions in 57 minutes, drawn from the official DVSA bank covering the Highway Code, road signs, vehicle safety and driving theory. You can flag tricky questions and review your answers before finishing. You need 43 correct to pass this section.

Part 2: hazard perception

You watch 14 short video clips of everyday driving and click when you spot a developing hazard. Earlier (genuine) clicks score more, up to 5 points per hazard. The pass mark is 44 out of 75. Don't click in a steady rhythm — the system scores that clip zero. See our full hazard perception test guide for the scoring window and technique.

Passing and your certificate

You must pass both parts in the same sitting; pass one and fail the other and you retake the whole test. A pass is valid for two years, within which you must pass your practical test or sit the theory again. Your result is printed before you leave.

Riding a motorcycle or driving a lorry or bus? The theory test works differently for those — see our motorcycle theory test and lorry & bus theory test guides.
