What should you do if you are threatened with a rear-end collision?

• Flash your brake lights early to alert the driver behind you
• Check your front zones for open space and move forward, if possible
• Check your rearview mirror for open space and move backward, if possible
• Both A & B
  Explanation:

  "If you are threatened with a rear-end collision, take these actions: 1. Flash your brake lights early to alert the driver behind you. 2. As the vehicle nears, check your front zones for open space and move forward, if possible. This precaution gives the driver approaching from the rear more time and space to stop safely. 3. If the intersection is clear, accelerate to give the other driver more space to stop. If your path is not clear, turn right."
