Answer: A. allowing more space
Most rear-end collisions can be avoided by allowing more space between your vehicle and the one ahead.
Why this is the answer
The handbook says tailgating is a major cause of crashes. When you follow too closely, the vehicle ahead can hide hazards, and you have no time to slow down if it stops suddenly. It also says that keeping good space margins and traveling at an appropriate speed help you avoid most collisions. Leaving room gives you time to react and stop safely, so allowing more space is the answer.
Why the other answers are wrong
- B. driving slowly — Simply driving slowly is not the handbook's point; it stresses good space margins and an appropriate speed, not slow speed by itself.
- C. driving faster — Driving faster reduces your space and time to respond, which works against the handbook's advice to maintain good space margins and travel at an appropriate speed.
- D. quicker reflexes — Quicker reflexes are not presented as the way to prevent most rear-end crashes; the passages emphasize leaving enough space and having time to stop.
Remember it
Think of space as your braking room: the more room you leave, the more time you have if the car ahead stops.
