Different road features and surface conditions introduce specific vehicle handling challenges and hazards. How should each road feature be matched with its correct safe driving technique and hazard response?
- Speed cushions installed side-by-side across a residential carriagewayPosition the vehicle centrally to straddle the raised profile without swerving towards the kerb or cycle lanes
- Wet metal inspection covers and ironwork located on the radius of a bendAvoid harsh steering inputs or sudden acceleration while tyres cross the slick surface to prevent lateral skidding
- A continuous sequence of full-width raised road humps within a 20 mph zoneMaintain a steady, moderate pace throughout the calmed corridor rather than accelerating and braking harshly between individual humps
- High-friction anti-skid surface dressing laid on the approach to a pedestrian crossingRecognize the increased grip available for emergency deceleration without treating it as justification for late or heavier braking
Cevap
Speed cushions match with central positioning to straddle the cushion without veering into cycle lanes; wet metal inspection covers match with avoiding abrupt steering or acceleration to prevent skidding; a continuous sequence of road humps matches with maintaining a steady, low speed throughout; high-friction anti-skid dressing matches with recognizing emergency grip without braking late or aggressively.
Each traffic management and surface feature requires a dedicated defensive driving response: speed cushions require maintaining a centered track to protect cycle paths; wet ironwork requires smooth, neutral vehicle inputs to maintain adhesion; series of road humps require a constant low speed; and high-friction surfacing requires standard cautious approach speeds while benefiting from enhanced emergency friction.
