At speeds below 40 mph, you should allow at least one second of following distance for every 10 feet of your vehicle. Follow the same formula when traveling at faster speeds, then add one additional second to your following distance. Remember that larger vehicles require more space to stop than smaller vehicles.
14. What is the best way to stop if your brakes fail while you are driving downhill?
Explanation
If your brakes fail on a downgrade, you will need to quickly find something outside that can stop your vehicle. An escape ramp is the best option. If no escape ramp is available, use the least hazardous available option, such as driving into an open field or side road that flattens out or turns uphill.
