Practical test

The most common reasons people fail their driving test

The faults examiners see most often, and the habits that stop you making them.

Updated 18 October 20262 min read

Most failed tests come down to the same handful of habits. DVSA publishes the most common reasons for failing, and the top of the list rarely changes. Here they are, with what to do about each.

1. Not looking properly at junctions

The most common reason by far. Learners pull out without looking well enough in every direction, or look but don't judge the speed of traffic.

What to do: slow down early, look right, left and right again, and take a second look before you commit. If you can't see, creep forward until you can.

2. Not using mirrors when changing direction

Not checking mirrors before signalling, turning, changing lanes or changing speed.

What to do: use the routine mirrors, signal, position, speed, look, every time, even when the road looks empty.

3. Not moving off safely

Pulling away from the side of the road, or after stopping, without checking properly, including the blind spot over your shoulder.

What to do: check all mirrors and your blind spot before you move off, every time.

4. Poor position when turning right

Not positioning just left of the centre of the road (or in the right lane) when turning right, or cutting the corner.

What to do: get into position early, and keep the car straight while you wait so you're not pushed into oncoming traffic.

5. Not responding properly to traffic lights

Going on red, not stopping at the line, or waiting too long at green arrows or filter lights.

What to do: read the lights early as you approach, and know what each signal means.

6. Poor positioning during normal driving

Driving too close to the kerb or the centre line, or wandering between lanes on roundabouts.

What to do: keep a steady, central position in your lane, and follow lane markings on roundabouts.

7. Losing control when moving off

Stalling repeatedly, rolling back on hills, or moving off jerkily.

What to do: practise clutch control and hill starts until they're automatic (or consider an automatic car).

8. Not keeping control of the steering

Steering too early or too late, or not keeping both hands on the wheel when you need them.

9. Not responding to traffic signs

Missing speed limit changes, no entry signs or stop signs.

What to do: look well ahead and read every sign. Know your signs: revisit Know Your Traffic Signs.

10. Not responding to road markings

Ignoring lane arrows, box junctions or "keep clear" markings.

How to avoid them

The best preparation is a mock test with your instructor under real test conditions. It shows exactly which of these habits you still need to fix, while there's still time.
