In a passenger car with normal grip, outside a tunnel, what minimum separation is recommended by the practical two-second rule?

Correct answer

At least two seconds, increased when conditions require it.

Two seconds as a practical guide, not a universal guarantee or legal minimum for every situation. Increase separation in rain or other risks and obey specific distance requirements. If drowsy or fatigued, stop safely to rest.
