Observation, Speed & SpaceStandalone practice
The car ahead of you passes a road sign. You count "one-thousand-one, one-thousand-two," and your car reaches the same sign. What does this tell you?
A follows B past a fixed roadside sign. The card states the observed two-second gap.
Correct answer: You are too close; drop back until you reach the sign after at least a three-second count.
Why
A time gap works at any speed, because the distance it gives you grows as you go faster. Rear-end crashes are very common, and they usually happen when a driver follows too closely to stop when the car ahead stops suddenly. Leave more than three seconds on wet or icy roads, or when you are tired.
