Reasons for Failing

1. Poor observation at junctions

This is one of the most common reasons for failing. Not looking properly before pulling out, misjudging the speed of oncoming traffic, or hesitating too much at roundabouts can all be dangerous.

Tip: Always take your time to look both ways and only go when it’s 100% safe.

2. Not using mirrors correctly

Many learners forget to check their mirrors before changing speed or direction. Failing to check your mirrors — especially the rear-view and side mirrors — before signalling, turning, or slowing down will likely result in a fault.

Tip: Follow the MSM routine – Mirrors, Signal, Manoeuvre – every time.

3. Poor control during manoeuvres

Reverse parking, bay parking, and pulling up on the right are all tested in the UK driving test. If you don’t show good control or forget to check your surroundings while reversing, it could cost you the test.

Tip: Practise your manoeuvres slowly and always check all around before and during reversing.

4. Responding incorrectly to traffic signs

Missing a speed limit change, ignoring a “give way” sign, or entering a bus lane by mistake are all serious errors. These signs are there to keep roads safe — and the examiner will expect you to follow them without being prompted.

Tip: Stay alert and scan the road ahead for signs and markings, especially in unfamiliar areas.

5. Lack of confidence or over-caution

Being too hesitant can be just as problematic as being too bold. If you wait too long at roundabouts or junctions when it’s clearly safe to go, it can disrupt traffic flow and lead to a fault.

Tip: Practise decision-making with your instructor to build confidence in real traffic situations.
