Common faults at Grantham (Somerby)

Most Common Fail Reasons

Junctions - observation12.5%
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 - safely5.1%
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 signs4.0%
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 - steering3.7%
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.
Move off - control3.1%
Common Scenarios:
  • Stalling from a parked position or in traffic.
  • Rolling back a considerable amount when moving off.
  • Attempting to move off when a gear is not selected.
Why More Common Here:
  • Hilly areas, especially around junctions.
  • Hilly roads with slow stop-start traffic, requiring consecutive hill starts.
Response to traffic lights3.1%
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.
Judgement - crossing2.9%
Common Scenarios:
  • Turning right across the path of an oncoming vehicle, failing to anticipate its speed.
Why More Common Here:
  • Certain right turns on fast roads with poor visibility, requiring expert judgement.
Response to road markings2.9%
Common Scenarios:
  • Driving in an incorrect lane that was clearly marked.
  • Ignoring lane arrows at junctions (e.g. left turn only).
  • Ignoring a give way line and assuming priority.
  • Stopping within a cycle box, not respecting advanced stop lines.
Why More Common Here:
  • Road markings worn away due to infrequent maintenance and/or heavy traffic.
  • Complex or confusing lane restrictions.
  • Road markings can be easily missed in slow moving traffic, especially when other road users may not follow them.
  • Give way lines draw in unusual places.
Junctions - turning right2.6%
Common Scenarios:
  • Incorrect positioning when turning right at junctions.
  • Not positioning to the right of the road when turning right.
  • Turning right at a roundabout using the incorrect lane.
  • Not using the waiting area in the middle of the road when waiting to turn right, therefore blocking traffic behind.
Why More Common Here:
  • Confusing road layouts, worn road markings and circuitous test routes involving waiting area for right turns.
  • Roundabouts with many exits making lane choice less obvious.
  • Roundabouts whose signs contradict the actual road geometry, making the 12 o'clock rule difficult to follow.
Progress - undue hesitation2.5%
Common Scenarios:
  • Not emerging from a junction when it is safe to do so.
  • Waiting unnecessarily for another road user to pass who has clearly given way to you.
  • Failing to maintain momentum when joining a clear roundabout.
  • Ignoring shields and exit signals on mini-roundabouts and therefore missing many opportunities to proceed.
Why More Common Here:
  • Areas and times with fast, flowing traffic and non-obvious gaps.
  • Busy mini-roundabouts.
  • Test routes with stops along busy main roads.

Most Common Minor Faults

Move off - safely0.52
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.
Mirrors - signalling0.35
Common Scenarios:
  • Checking mirrors after or at the same time as signalling.
Why More Common Here:
  • Test routes that involve frequent or rushed lane changes.
Move off - control0.35
Common Scenarios:
  • Stalling from a parked position or in traffic.
  • Rolling back a considerable amount when moving off.
  • Attempting to move off when a gear is not selected.
Why More Common Here:
  • Hilly areas, especially around junctions.
  • Hilly roads with slow stop-start traffic, requiring consecutive hill starts.
Junctions - observation0.32
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.

  • 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.
Progress - speed (too slow)0.27
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.
Control - gears0.21
Common Scenarios:
  • Selecting a low gear at high speed, causing a sudden loss of speed and danger for vehicles behind.
  • Selecting a high gear at low speed, and possibly stalling.
Why More Common Here:
  • Test routes with numerous fast stretches of road, necessitating higher gears and more shifting.
Mirrors - change speed0.21
Common Scenarios:
  • Failing to check mirrors when slowing down.
  • Failing to check mirrors when speeding up, creating danger for anyone overtaking.
  • Accidentally slowing due to improper gear selection.
Why More Common Here:
  • Roads with harsh speed limit changes.
  • Fast hilly roads where learners may forget to downshift as needed, causing accidental slow-downs.
Signals - timed0.20

  • Signalling too late for the signal to be effective.
