How the test is marked
You can pass with up to 15 driving faults (minors). A serious or dangerous fault means automatic failure. Faults are recorded in categories such as junctions, use of mirrors and positioning.
Top reasons for failing
According to DVSA data, the most common reasons are:
- Observation at junctions
- Mirrors: not using them, or not acting on what you see
- Reversing around a corner or into a bay
- Positioning on the road
- Steering control
- Moving off safely
How to avoid them
Slow down at junctions and look properly before committing. Use mirrors before signalling, changing speed or direction. Practise manoeuvres until they are second nature. A mock test with honest feedback shows you exactly where you lose marks.
