Final answer:
Expert drivers should scan the driving scene several seconds ahead to anticipate hazards and make informed decisions. Scanning ahead helps identify potential dangers and allows adjustments to speed and position. For example, if a driver sees a pedestrian crossing ahead, they can slow down in advance.
Step-by-step explanation:
Expert drivers should ideally scan the driving scene several seconds ahead of their current position to anticipate potential hazards and make informed decisions. This is generally referred to as 'looking ahead' or 'scanning ahead' while driving.
By scanning the road ahead, expert drivers can identify potential dangers or changes in the driving environment, such as slow-moving vehicles, pedestrians, or upcoming intersections. This allows them to adjust their speed, position, and lane choice to maintain safety and avoid potential collisions.
For example, if a driver notices a pedestrian crossing the road several seconds ahead, they can start slowing down in advance to ensure a safe stop, rather than suddenly slamming on the brakes. Similarly, if they observe a signaled intersection ahead, they can prepare to slow down or stop in time.
