Explanation:
"Rear-end collisions are a major driving problem. They can be avoided if you follow a few simple rules:
1. 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.
2. Watch for shrinking distance between your car and the one ahead. It’s a sure sign of danger.
3. Above all, leave plenty of space between your car and the car ahead of you as a safety cushion. "
