Use 4-second or more rule when being crowded by a tailgater, slippery roads, following motorcyclists on wet or icy roads, metal surfaces, gravel; driver behind you wants to pass, towing a trailer, following large vehicles that block your view ahead; see a bus, school bus or placard vehicle at railroad crossing, merging onto a freeway.
