stopping distance; total stopping distance
Technical term used in traffic safety and vehicle engineering; refers to the distance a vehicle travels from when the driver perceives a hazard until it comes to a complete stop.
On rainy days, stopping distance increases, so please keep your speed down.
I learned how to calculate stopping distance at driving school.
制動距離 refers specifically to the braking distance after the brakes are applied, while 停止距離 includes the reaction distance (空走距離) as well.
空走距離 is the distance traveled during the driver's reaction time before braking; 停止距離 is the sum of 空走距離 and 制動距離.
Compound of 停止 (ていし, 'stop') and 距離 (きょり, 'distance').
