Explanation
Rear-end collisions are almost always caused by drivers following too closely. Always keep a minimum following distance (the space between you and the vehicle in front of you) of three seconds during favorable weather and traffic conditions. This distance should be increased when driving in adverse conditions (rain, heavy traffic etc.). Maintaining a large enough following distance greatly helps avoid a collision with the vehicle in front of you.
