Seeing Hazards and Hazard Perception
What the exam tests
Seeing Hazards and Hazard Perception tests scanning, recognizing clues, and planning escape routes. The exam wants evidence that you see a hazard early enough to act smoothly.
Core rules
- Scan 12-15 seconds ahead and check mirrors every 5-8 seconds.
- Read clues: brake lights, swerving, stale green lights, work zones, parked cars, animals, shadows, and hill crests.
- Ask what if: if the hazard develops, where will I go? Keep an escape lane or shoulder option.
- Do not fixate; keep eyes moving and recheck mirrors.
- Slow down when the clue is ambiguous, especially at crests, curves, and intersections.
Worked example
On a two-lane road, brake lights flash beyond a crest. The clue is not just the car ahead; it suggests a stopped line. The driver slows before the crest, increases following distance, checks the shoulder, and avoids a blind pass. If the line is stopped, the driver already has time and space to stop.
Traps that cost marks
Staring at the hazard, scanning only the bumper, ignoring a stale green, and assuming a familiar road has no new hazard. Another common error is treating a shoulder as an escape route without checking that it is firm and clear.
Key idea
Hazard perception is not just seeing the danger; it is predicting where the danger will move next.
