1) Junctions: ineffective observation
Look, assess speed, commit. Don’t emerge late or misjudge speed at T-junctions/roundabouts/dual-carriageway slips.
Stats: Ineffective observation featured in many collisions. See DfT RAS tables.

Straight from the DVSA guidance, here are the most common reasons candidates fail — with quick tips and official resources to fix them. Use this as a checklist with your instructor before you book a test.

Use MSM (Mirror–Signal–Manoeuvre). Check before lane changes and when exiting roundabouts; avoid cutting across vehicles.
Blind-spot + mirrors every time (from kerb, hill, or from behind a parked car). After emergency stop, re-check rear before moving.
Position close to the centre line when safe. Use correct roundabout lane for right turns; don’t block following traffic.
Stop for red; proceed on green only if the junction is clear. Respect advanced stop lines for cycles.
Learn: Highway Code — traffic lights.
Smooth, timely inputs. Avoid “swan-neck” right turns, late steering around parked cars, and mounting the kerb when pulling up.
Follow arrows and lane lines; don’t straddle lanes on roundabouts or block box junctions.
Rule 129 (double white lines): Highway Code.
Obey “keep left”, STOP, NO ENTRY, bus-lane times, and roundabout lane signs. React promptly to speed-limit changes.
Hold centre of your lane, keep safe distance from kerb/centre line, and use right lane only when necessary.
Drive at a speed appropriate to limits and conditions (rain, fog, bends, high street). Always be able to stop within the distance you can see to be clear.

See before you move: Junction observation + MSM on every lane change and roundabout exit.
Position with intent: Correct lane for turns/roundabouts; hold lane centre; keep clear of box junctions.
Speed for safety: Drive to the limit and conditions — always able to stop within what you can see.
Driving test mistakes 2025 still catch many learners by surprise, but most are simple habits you can fix with the right plan. At HSA DRIVING SCHOOL, we teach calm routines that turn nerves into smooth, repeatable actions on test day.
The frequent faults include missed mirror checks, weak lane discipline, rushed roundabout entry, late stops at signs, and shaky clutch control. Examiners value observation more than speed, so steady checks before signalling, changing position, or adjusting pace will protect your mark sheet.
Manoeuvres cause stress because learners chase speed instead of control. Slow movements, clear reference points, and continuous observation earn confidence and consistency. Eco-safe inputs matter in 2025 too, so smooth acceleration and planned braking show maturity and forward thinking.
Weather multiplies errors when vision drops. We rehearse wet roads, glare, and fog so you read space early and keep margins wide. When you want mechanical simplicity, our automatic lessons reduce stalls and let you focus on road strategy.
Mirror-signal-manoeuvre made automatic. Build a rhythm: check mirrors, indicate, re-check blind spots, then act. Small, timely observations prevent minors turning into majors.
Roundabout timing. Scan early, commit only when your gap is certain, and maintain a steady approach speed. Confidence comes from consistency, not rushing.
Clutch and hill starts. Find the bite, hold still with control, and release smoothly. For a different path, try manual lessons with focused bite-point drills.
Manoeuvres without panic. Choose reference points, keep it slow, and look all around. Examiners prefer safe precision over fast parking.
You can shortcut months of guesswork with structured practice and realistic mock tests. Review your weak spots, repeat good habits, and track progress until everything feels natural.
