Stopping Sight Distance
10 meters for thinking distance and 17 meters for stopping
Antilock brakes do not increase the braking force.
Perception Distance + Reaction Distance+ Braking Distance.
Perception Distance, Reaction Distance and Braking Distance
The total stopping distance includes the perception distance, reaction time and braking distance. The distance that your vehicle is traveling and then pressing on the brake after seeing a hazard, is the total stopping distance.
It is the total stopping time.
Stopping distance for a motor vehicle is a combination of two factors.First the reaction time of the driver.Then the braking distance of the vehicle once the driver has reacted and applied the brakes.The two equal the stopping distance.
Most experts in the field agree on this. ABS does reduce braking distance on dry or wet pavement if they are used properly. On gravel and snow ABS may increase braking distance slightly. But ABS's main safety feature is not to decrease stopping distance, but is to allow control of the vehicle during an emergency stop, because it prevents wheel lock-up and a skid.
The greater the mass of the car and its occupants the longer the stopping distance that is required for the vehicle. Stopping distance is calculated by taking into account car mass and reaction time in braking
When traveling 30-mph, the braking distance is 45-feet, and the total stopping distance is 75-feet. This is the length of a semi-truck and trailer.
