What is the stopping distance at 50 mph?

• A. 150 feet
• B. 175 feet
• C. 200 feet
• D. 225 feet

Answer: (B)

The stopping distance at 50 mph is typically around 175 feet under ideal conditions, which include good weather, well-maintained brakes, and proper tire traction. This measurement includes the distance it takes for a driver to perceive a hazard, react, and then bring the vehicle to a complete stop. When traveling at higher speeds, the stopping distance increases significantly due to the physics of motion—specifically, the effect of speed on both reaction time and braking distance. At 50 mph, a driver has to account for both the time it takes to make the decision to stop and the actual distance the vehicle travels while decelerating. Hence, the selected answer reflects a reasonable estimate that aligns with established guidelines for stopping distances at that speed. As for the other options, distances that are too short fail to consider the reaction time and braking distance that need to be factored in when driving at such speeds, while those that are excessively long do not reflect practical averages used in driving norms.
