BDifficulty 2/5

A car follows another vehicle. To stop without colliding if it brakes suddenly, what following gap must generally be maintained?

Correct answer

Enough space to stop without colliding in those conditions.

Enough space to stop without colliding, taking speed, grip and braking capability into account. There is no fixed 50-metre gap for every car and situation. The additional gap to facilitate overtaking has separate rules and exceptions under article 54.2 and 54.3: it is not required in built-up areas, where overtaking is prohibited, with multiple lanes per direction or in traffic too congested for overtaking. The group-cyclist exception does not apply to this car.
