Explanation:
"To lower the risk of someone running into the rear of your vehicle:
1. Check your brake lights to make sure they're clean and working properly.
2. Know what is going on around you. Use the rear-view and side mirrors.
3. Signal well in advance for turns, stops, and lane changes.
4. Avoid sudden stops; slow down gradually and smoothly.
5. Drive with the flow of traffic (within the speed limit). Driving too slowly can be dangerous."
