safe-driving
What following interval does the manual recommend as a normal minimum?
- At least three seconds behind the vehicle ahead
- Exactly one second at every speed
- One car length regardless of speed
- Ten seconds only when driving in a city
Answer: At least three seconds behind the vehicle ahead. The three-second rule creates a moving time cushion rather than relying on a fixed distance that becomes inadequate as speed rises. Choose a fixed object, wait until the vehicle ahead passes it, and count before your own vehicle reaches that point. One second leaves little reaction room, and a single car length changes meaning with speed. Increase the count to four seconds when weather or road conditions are poor.
