The stopping distance of the motor vehicle is one of the most significant variables that affect road safety. At the stopping impact driver, vehicle, road, traffic on the road and the conditions prevailing in the area. The speed of vehicles is one of the very important value which affects the length of the stopping of the vehicle. The speed of the dependent and the response time and braking distance. The way to respond is the path that the vehicle crosses during the hazard perception and obstacles by the driver and his reactions necessary to begin the process of braking and brake system time to take effect. The braking distance is the path that the vehicle crosses the duration of braking. On the driver's reaction time affect his subjective characteristics, physical and mental state of the driver and the conditions of objective circumstances. The importance of stopping the vehicle is emphasized in traffic accidents such as vehicle collision when driving in sequence, flying to motorcyclists, bicyclists, pedestrians and hitting an object on or near the road. Influencing factors that play a significant role in achieving the shortest stopping vehicles such as reducing the speed of the vehicle, increasing the coefficient of friction between the tire and the road surface overlay, proper maintenance of pavement and road surface overlay, increasing roadworthiness and timely information to the driver on the weather and incidental factors the road would significantly increase road safety.
