Observation, Speed & SpaceStandalone practice
Why should a driver reduce speed when headlights illuminate only a short distance ahead?
Blue car A faces east in the center of its lane on an unlit straight two-way road. Its working headlights illuminate part of the road ahead. The image does not show its stopping distance or identify a correct answer.
Correct answer: The vehicle must be able to stop within the distance the driver can see to be clear.
Why
At night, speed should leave enough visible road for perception, reaction, and braking before an unseen hazard.
