Safe following distance

Safe following distance: criteria and special cases Following distance also depends on the driver's physical and mental condition Following distance also depends on tyre grip Reaction distance is travelled before braking begins Approximate distance travelled in one second at common speeds Driver distraction can cause collisions Distance travelled in one second Braking distance increases with the square of speed Low grip increases braking distance Total stopping distance is reaction distance plus braking distance Speed and poor road conditions increase total stopping distance Concentration, speed, load and grip affect following distance Engine fuel type does not determine following distance Keep a safe following distance before overtaking Increase the gap behind a projecting or unstable load
