C1Difficulty 3/5

When the additional 50-metre gap under Article 54(2) applies to vehicles with MAM above 3,500 kg or total length above ten metres that do not signal an intention to overtake, what purpose does it serve beyond the gap needed to stop without collision?

Correct answer

Allow a following vehicle to overtake safely.

To allow a following vehicle to overtake safely. This additional gap does not by itself guarantee avoidance of a rear-end collision: maintain the stopping gap needed for speed, grip and braking, which may be greater. Article 54(3) exempts this additional gap in built-up areas, where overtaking is prohibited, with more than one lane in your direction or when saturation prevents overtaking. Its overtaking purpose must not be confused with a fixed braking distance.
