What each attempt draws
Every start picks a fresh set in this topic mix, so no two attempts are the same.
- Heavy vehicle technical checks33
- Drivers' hours, tachographs and documents24
- Rules of the road24
- Truck loads and goods19
Why it does not repeat itself
- At least 10 questions show a road sign picture, and some ask you to pick the sign that matches a meaning.
- No two questions rest on the same rule of law.
- No two questions open with the same 4 words.
- No more than 5 questions come from one lesson.
- The correct answer never sits in the same position more than 3 times in a row.
Before you start
Using the test
While you answer
- Press A to D to choose an answer and Enter for the next question.
- Flag a question you want to come back to, and open the question grid to jump to it.
- The timer stays on screen; when it reaches zero, the test is marked as it stands.
When you finish
- Your score and whether it passes, then how you did in each topic.
- A review of every question with the right answer and the law behind it.
- The questions you got wrong are saved on this device only, never sent to us, and your next mock avoids repeating the questions you just saw.
