Final answer:
The air brake lag distance at 55 MPH adds about 32 feet to your stopping distance.
Step-by-step explanation:
The air brake lag distance at 55 MPH adds about 32 feet to your stopping distance. When driving at 55 MPH, it takes a certain amount of time for your foot to reach the brakes and for the brakes to actually begin to slow down the car. This is called the lag time or reaction time. During this time, the car continues to move forward at the same velocity, adding to the total stopping distance. So, if your stopping distance is determined to be a certain number of feet at a specific speed, the lag distance at 55 MPH would add 32 feet to that total stopping distance.
