At what speed does the bus require a stopping distance of 125 feet?

• A. 30 mph
• B. 45 mph
• C. 55 mph
• D. 60 mph

Answer: (B)

The stopping distance for a vehicle, including a school bus, is influenced by speed, the reaction time of the driver, and road conditions. At 45 mph, the formula typically used to calculate stopping distance suggests that a bus will require about 125 feet to come to a complete stop. This includes both the distance traveled during the driver's reaction time and the distance needed for the vehicle to decelerate and stop fully. As speed increases, the stopping distance grows significantly due to the increased momentum of the bus, which requires more distance to reduce that momentum to a halt. Thus, at speeds higher than 45 mph, it becomes evident that the stopping distance exceeds 125 feet, as both the reaction and braking distances add up to a greater total.
