Rules of the Road
According to the Ontario Driver's Handbook, the safe following distance behind the vehicle ahead in normal conditions is at least:
Show Answer & Explanation
Correct Answer: B. Two seconds
The two-second rule gives you enough reaction time and stopping distance in normal conditions. On slippery roads or at higher speeds, increase to 3 seconds or more. Too-close following ('tailgating') is a top cause of rear-end collisions.
Why the other answers are wrong
- A.One secondOne second is too little for human reaction plus braking distance; the minimum in good conditions is two.
- C.Five secondsFive seconds is recommended for bad weather or heavy vehicles; not a general-purpose minimum.
- D.Ten car lengthsCar-length measures vary with vehicle size and speed; the handbook uses the time-based two-second rule because it scales with speed.
