Common faults at Slough (London)

Most Common Fail Reasons

Mirrors - change direction9.2%
Common Scenarios:
  • Failing to check mirrors when exiting a roundabout.
  • Failing to check mirrors when changing lanes.
Why More Common Here:
  • Complex multi-lane roundabouts and one-way systems.
Response to traffic lights7.8%
Common Scenarios:
  • Driving through a red light.
  • Driving through an amber light when you could have stopped safely.
  • Hesitating unnecessarily at a green light, impeding the flow of traffic.
  • Incorrectly stopping at a red light that is meant for other drivers.
  • Ignoring or misinterpreting a green arrow filter light.
  • Not waiting in the middle of a box junction when turning right.
Why More Common Here:
  • High traffic volume in the area can pressure learners to avoid stopping for amber lights.
  • Confusingly located traffic lights.
  • Traffic lights placed on fast sections of road where learners feel pressured to make good progress.
  • Traffic lights placed within roundabouts, where learners are too focused on lane position and observations.
Junctions - observation7.6%
Common Scenarios:
  • Emerging at a T-junction or roundabout and causing another vehicle to slow down.
  • Emerging from a junction without adequate observations (even if clear).
  • Sailing through a crossroads without stopping and looking.
  • Joining a dual carriageway via a sliproad without sufficient mirror and blind spot checks.
  • Turning right in front of oncoming traffic, causing them to slow down.
Why More Common Here:
  • Junctions onto busy roads with fast flowing traffic, small gaps and the requirement to build speed quickly to avoid slowing others behind.
  • Short, curvy or otherwise awkward sliproads onto dual carriageways.
  • Busy high streets and main roads with poor visibility and bikes overtaking.
Move off - safely4.7%
Common Scenarios:
  • When parked on the road, moving off and causing oncoming traffic to brake or swerve.
  • Not checking mirrors and blindspots when moving off from a parked position.
  • Not completing all 360° observations when continuing after an emergency stop.
Why More Common Here:
  • Test routes involve stopping on busier roads.
  • Test routes involve stopping on bendy residential roads with restricted visibility.
Response to traffic signs4.4%
Common Scenarios:
  • Not coming to a complete stop at a stop sign.
  • Attempting to drive through a no-entry sign.
  • Attempting to drive through any other sign that restricts access (e.g. buses only).
  • Ignoring a give way sign and assuming priority.
  • Ignoring a keep left sign.
Why More Common Here:
  • Stop signs are rare in the UK, but may show up in this test centre area.
  • Confusing one-way systems.
  • Complex road signs restricting access (e.g. bus-only at certain times).
Control - steering4.1%
Common Scenarios:
  • Steering too much, too little, too early or too late.
  • Mounting the curb when steering out of a junction.
  • Briefly driving on the wrong side of the road when turning through a junction.
Why More Common Here:
  • Tight junctions and narrow roads.
  • Sharp left or right turns on test routes.
Judgement - meeting3.8%
Common Scenarios:
  • Failing to slow down or adjust your position when approaching an oncoming vehicle on a narrow road.
  • Misjudging the speed of an oncoming vehicle and failing to allow sufficient space for it to pass safely.
  • Continuing towards other vehicles when they have priority.
Why More Common Here:
  • Narrow residential roads, particularly those lined with parked cars.
  • Residential roads with hills and bends, requiring faster reaction time.
Progress - speed (too slow)3.7%
Common Scenarios:
  • Driving significantly below the speed limit on a clear road without a valid reason (especially if it impacts drivers behind or causes them to overtake).
  • Being hesitant to build speed on a sliproad so as to merge safely.
  • Slowing down excessively for minor hazards, such as slight bends.
  • Losing speed due to improper gear selection on a hill.
Why More Common Here:
  • Test routes that cross both 20 mph residential zones and regular 30 mph roads - learners may 'hedge' their bets by driving at 20 until they are sure the limit is 30.
  • Rural national speed limit roads.
  • Fast roads with hills and bends, requiring frequent gear changes to maintain progress.
  • Short sliproads necessitating confident acceleration.
Positioning - normal driving3.4%
Common Scenarios:
  • Not driving in the centre of the lane.
  • Driving for too long in the right hand lane of a dual carriageway, for no reason.
  • 'Straight-lining' a roundabout.
  • Not driving in the bus lane when it is allowed at that time.
Why More Common Here:
  • Many timed bus lanes around test centre.
  • Multi-lane roundabouts with worn lane markings.
Use of speed (too fast)3.3%
Common Scenarios:
  • Driving above the posted speed limit.
  • Failing to reduce speed when approaching a hazard, such as a pedestrian crossing or a bend in the road.
  • Driving too fast on a road with potholes or poor surface condition (regardless of the posted speed limit).
  • Driving too fast on a national speed limit road (60 mph is often too dangerous).
  • Driving at a speed that is unsafe for the weather - rain, fog, or ice.
Why More Common Here:
  • Recently changed speed limits that conflict with old limits displayed on satnav.
  • Sudden speed limit changes, especially on exit sliproads.
  • Inadequate signage, road markings and traffic calming measures.
  • Test routes that cross both 20 mph residential zones and regular 30 mph roads.
  • 20 mph main roads where locals ignore the limit and overtake learners, causing pressure to keep pace.
  • Clearly signed 30/40/50/NSL roads that pressure learners to make progress despite potholes, bends, etc.
