In which situation should you tap the brakes so your brake lights blink, or use your hazard flashers?

Correct answer: You want to alert other drivers to a crash ahead.

Answer options

  1. AYou want to thank a driver who let you merge.
  2. BYou want to alert other drivers to a crash ahead. Correct
  3. CYou are reversing out of a spot in a parking lot.

Why

Blinking your brake lights or turning on the hazard flashers lets the people behind you know early that traffic is stopping for a crash ahead, which gives them room to slow down. These signals warn of danger or an unexpected slowdown; they are not a way to thank another driver or something to use while reversing out of a parking spot.

Tip Hazard flashers are for warning others of a sudden danger, not for excusing double-parking or for ordinary driving.
