Final answer:
Lightly apply your brakes to flash the brake lights in various situations: when a police car is approaching, when a driver is tailgating, and when you are about to exit the road.
Step-by-step explanation:
When you lightly apply your brakes to flash the brake lights depends on the situation:
- When a police car is approaching from the other direction, it is a good practice to lightly apply your brakes to warn the police car and other drivers of your presence.
- If a driver is tailgating your vehicle, you can lightly apply your brakes to signal to them that they are following too closely and should maintain a safe distance.
- When you are about to exit the road and need to slow down, lightly applying your brakes can help indicate to other drivers that you are about to make a maneuver.
