The 6 Most Common Driving Test Faults in the UK (and How to Avoid Them)

Every year the DVSA publishes the reasons people fail the practical test, and every year the list barely changes. The most common driving test faults are not exotic mistakes or unlucky moments. They are everyday habits, repeated at the wrong time in front of an examiner.

That is encouraging, if you think about it. With the national pass rate sitting at 48.7%, the difference between passing and failing usually comes down to a handful of known, fixable behaviours. Here are the six that catch the most candidates, and what to do about each one.

First, how the marking works

You can pass with up to 15 driving faults, often called minors. One serious or dangerous fault, a major, is an automatic fail. Most fails are not caused by one dramatic error but by a routine action done carelessly at a moment that made it serious, such as pulling out of a junction without looking properly while a cyclist approached.

1. Not looking properly at junctions

Year after year, observation at junctions is the single most common reason for failing the UK driving test. It is rarely about not looking at all. It is about glancing without seeing: a quick token look right while your foot is already lifting off the brake.

How to avoid it: make your observations deliberate and full. Look right, left and right again, and actually process what you see before committing. If your view is blocked, creep forward slowly and look again. Examiners are happy to wait; they are not happy to brake.

2. Mirror checks before changing direction

The second great filler of fail sheets is mirrors, specifically failing to check them before signalling, changing lanes or turning. Under pressure, learners skip the check or do it after the manoeuvre has already started, which defeats the point.

How to avoid it: drill the mirror-signal-manoeuvre routine until it survives stress. This is one of the habits worth measuring rather than guessing at. Clutch tracks your mirror checks in context, at junctions, roundabouts and lane changes, and shows you after each drive exactly where the routine held up and where it collapsed.

3. Steering and road positioning

Poor control covers wandering within the lane, clipping kerbs on turns, and bad positioning on roundabouts and dual carriageways. Examiners read sloppy positioning as a sign you are at the limit of your concentration.

How to avoid it: look further ahead. Most steering problems are really vision problems; the car goes where your eyes go. On roundabouts, choose your lane early and hold it, and practise the exits you find awkward until they are boring.

4. Responding to traffic lights and road markings

Rolling through an amber that was comfortably stoppable, missing a stop line, drifting across hatched markings or ignoring lane arrows all sit in this category. These faults often appear late in the test, when concentration dips.

How to avoid it: treat every set of lights as a decision point you have planned for, not a surprise. Scan for markings early, especially at complex junctions where lanes are signed well before the turn.

5. Speed: too fast, and too slow

Examiners mark speeding, but they also mark hesitancy. Crawling at 20 in a clear 30 zone, or stopping at a roundabout when there was a safe gap, tells the examiner you are not reading the road. Plenty of careful, capable learners fail for being too cautious.

How to avoid it: know the limit at all times, and drive up to it when conditions allow. If you find yourself hesitating at junctions, work on gap judgement with your instructor in busy conditions until decisions come faster.

6. Pedestrian crossings

Failing to give way at a zebra crossing, moving off while a light-controlled crossing is still red, or approaching crossings too quickly to stop safely are all common majors. Pedestrians are the one road user examiners protect without compromise.

How to avoid it: scan the pavement, not just the crossing. A person walking towards a zebra crossing is your cue to be slowing already, and that anticipation is exactly what examiners want to see.

Train the patterns, not the panic

None of these six faults requires more natural talent. They require honest feedback about your own habits, because the gap between how you think you drive and how you actually drive is where fails live. Ask your instructor to be specific after every lesson, do full mock tests before booking the real thing, and use your practice drives to gather evidence. Clutch scores every drive against DVSA standards, so you can watch these exact fault areas improve week by week.

Frequently asked questions

How many minor faults are allowed on the driving test?

Up to 15 driving faults, with no serious or dangerous faults. Repeating the same minor fault throughout the test can be upgraded to a serious fault, so patterns matter as much as totals.

Can I fail for driving too slowly?

Yes. Driving well below the limit on a clear road, or hesitating at junctions when safe gaps appear, is marked as a fault and is one of the more common reasons careful learners fail.

What is the difference between a minor and a major fault?

A minor is an error that does not put anyone at risk. The same error becomes serious or dangerous when another road user has to react to it, or could have been harmed. Context decides, which is why observation habits matter so much.
