Pay strict attention to your driving when following another car.
Watch for brake lights on the four or five cars down the line. It will increase your response time. Shift your foot to the brake pedal as soon as you see brake lights go on ahead so you can stop if needed.
Monitor for shrinking distance between your car and the one ahead. It's a sure sign of danger.
Watch for stopped vehicles on the shoulder ahead. It's sometimes hard to tell whether a car in the distance ahead is moving or stopped. Compare the car in question to a fixed object.
Look for problems that might develop for the driver ahead of you so you have more time to react.
Leave plenty of space between your car and the car ahead of you as a safety cushion.
Slow down and prepare to stop if the car ahead of you signals for a left turn.
