Abstract
A tailgating safety system for a vehicle includes a distance determiner for determining a distance of the vehicle from objects which are leading or following the vehicle. The system also includes a speedometer for determining a speed of the vehicle and an alarm. If the speed of the vehicle is greater than a predetermined speed, and the distance of the vehicle from another object is less than a predetermined distance, then the alarm is activated to advise the driver that at the speed the vehicle is traveling, the distance between the vehicle and the object is not a safe traveling distance.
