What is the stopping distance for a vehicle traveling at 30mph?

55 ft
65 ft
75 ft
85 ft

The correct answer is: 75 ft

The stopping distance for a vehicle traveling at 30 mph is typically around 75 feet. This distance includes both the thinking distance and the braking distance. The thinking distance is the distance a vehicle travels while the driver is reacting to the situation, and it can be calculated based on the speed of the vehicle. At 30 mph, the thinking distance would be approximately 15 meters (or about 49 feet). The braking distance, which is the distance the car travels from the point at which the brakes are applied to when it comes to a complete stop, generally increases with speed. For a vehicle traveling at 30 mph, the braking distance is around 36 feet, which, when added to the thinking distance, results in a total stopping distance of about 75 feet. This understanding is crucial for drivers to ensure they maintain a safe following distance to allow for adequate braking time in various conditions. Managing stopping distance is vital for effective accident prevention and overall road safety.
