Question

Difficulty: MediumContinuous Scanning and Anticipation

When driving along a street with parked vehicles, observing the angle of their front wheels and watching for exhaust emissions are effective visual scanning techniques to anticipate a vehicle pulling out.

Answer: Answer

Answer

True
Continuous scanning involves looking for early physical cues—such as turned front tyres, exhaust emissions, illuminated brake lights, and driver presence—so that potential hazards can be anticipated well before a vehicle enters your path.

Step-by-Step Solution

1
Analyze the visual scanning cues associated with stationary vehicles preparing to enter traffic.
Front wheels turned outwards toward the carriageway and active exhaust emissions indicate that the engine is running and the driver may be preparing to pull away.
Effective anticipation requires recognizing preliminary physical signs of hazard development before movement occurs.
2
Evaluate how identifying these cues impacts driver response and safety margins.
Noticing these indicators early allows the driver to adjust road position, check mirrors, and moderate speed smoothly without abrupt braking.
Proactive observation prevents emergency reactions and reduces the risk of side-swipe or rear-end collisions.
