The sign informs drivers on conventional or multi-lane roads of the mandatory minimum distance between vehicles on sections where rear-end collisions are frequent. To make compliance easier, the road surface is usually marked with chevron symbols that the driver should use as a reference, maintaining at least the minimum number indicated by the sign between their vehicle and the one ahead. This helps ensure safety and traffic flow.
