Explanation
Rear-end collisions are almost always caused by drivers following too closely. Drivers should keep a minimum following distance of four seconds during normal weather and traffic conditions. They must increase this distance if the weather or traffic conditions worsen. Maintaining a large enough following distance helps avoid collisions, because it allows drivers to have more time to react to sudden hazards.
