Correct answer
Enough to stop without collision if the vehicle ahead brakes suddenly.
Keep enough distance to stop without collision if the vehicle ahead brakes suddenly, accounting for speed, grip and braking capability. With more than one lane in the same direction, the additional Article 54(2) gap to facilitate overtaking does not apply, including the 50-metre minimum for heavy vehicles or those longer than 10 metres. This does not make 50 metres always sufficient or prohibit a larger margin. Tunnels and signs may impose other minima; they are excluded here.
