The Driving Dynamics Safety Team
One-third of all crashes involving two or more vehicles, almost two million annually, are rear-end collisions.
More than 85 percent are caused by a combination of insufficient following distance and driver inattention.
When you’re driving, the one space you can completely control is the distance from your vehicle to the vehicle in front of you. This distance is known as your safety zone. It can give you a One Second Advantage™, not only in reacting to situations that arise in front of you, but around and behind you. Awareness of the vehicles in front of you and those behind you is critical in managing your safety zone to prevent rear-end collisions.
A safety zone of at least two seconds is recommended during normal conditions. Inclement weather, traffic conditions, and personal preferences could all require the safety zone to be larger.
