Brake lag distance at 55 mph is how many feet?

Explanation:
Brake lag distance is the distance the vehicle travels from the moment you press the brake until the brakes actually start to slow the vehicle. At 55 mph, the vehicle moves about 80.7 feet each second. If the brake system takes roughly 0.4 seconds to engage, you’d cover about 32 feet in that time before braking begins. So the brake lag distance is about 32 feet, which is why this option is the best choice. This distance is part of the overall stopping distance, occurring before braking forces take effect.
