Why people fail the driving test

Roughly half of car tests end in a fail, and the reasons repeat. DVSA publishes the top ten every year and the list barely moves. What follows is that list, translated from the marking sheet into what actually happened in the car, with the one habit that removes each fault.

1. Junctions: observation

The most common serious fault by a distance. It is rarely a crash-in-waiting; it is pulling out of a side road having looked, but not looked long enough or late enough to see the car that was hidden behind the parked van. Examiners want to see your head turn both ways, and turn again just before the wheels roll. The fix is a rule, not a skill: look, look again, then go. If you cannot see far enough, creep until you can, and look again.

2. Mirrors: change of direction

Signalling to move out without checking the mirror first, or changing lane on a dual carriageway with a glance that came after the steering started. The examiner sees your eyes in the rear-view mirror and knows the order things happened in. Say the order out loud in lessons until it is automatic: mirror, signal, move. Not signal, mirror, move.

3. Control: steering

Mounting the kerb on a left turn, drifting across the centre line on a right turn, or crossing hands in a way that loses the wheel for a moment. Most steering faults are speed faults in disguise: the car was going too fast for the turn. Slow earlier, steer later.

4. Junctions: turning right

Cutting the corner, or positioning too far left so oncoming traffic cannot pass. The examiner wants you to hold your position just left of centre, wait for a gap, and turn without clipping the corner. If you are not sure whether the gap is enough, it is not.

5. Response to signals: traffic lights

Stopping in the box at a red, going through an amber that was already old, or sitting at a green filter arrow. Amber means stop unless stopping would be dangerous; if you are close enough that braking hard is the only option, you are already committed.

6. Move off: safely

Pulling away from the kerb without checking the blind spot over your right shoulder. It happens most after a manoeuvre, when your mind is still on the reverse. Every single move-off, including the one at the end of the test back at the centre, needs the shoulder check.

7. Positioning: normal driving

Hugging the kerb, or riding the centre line. Aim for the middle of your lane and keep about a door's width from parked cars. On roads without markings, imagine the centre line and stay to the left of it.

8. Response to signals: road markings

Straddling lane arrows at a roundabout, stopping over a stop line, or ignoring a "keep clear" box. These are the faults instructors call "not reading the road". Look further ahead; the markings that matter are 50 metres away, not under the bonnet.

9. Move off: control

Stalling on a hill, or rolling back. One stall on its own is usually a minor. A stall that causes someone behind you to react is not. If you stall, handbrake, neutral, restart, and start the move-off routine from the beginning, including the mirrors.

10. Reverse park: control

Ending up more than a car's length from the kerb, or touching it. The fix is to go slower than feels natural. Reversing at a walking pace is not a fault; reversing quickly and stopping to correct is.

What this list is telling you

Six of the ten are observation or sequence faults, not car-control faults. The test is mostly about looking, and about looking in the right order. When you look at a centre's pass rate, remember that lower rates are usually about how much there is to look at on the local roads: more junctions, more traffic, more chances to miss something. Practising on those exact roads is the most direct way to bring the number up.

DVSA has published this ranking every year since 2007/08 and the order barely moves. If you want the raw table and the nineteen-year trend rather than the explanation, it is on the most common driving test faults page.
