Practice question

What is the primary purpose of warning devices at a breakdown site?

  1. Alert oncoming traffic and prevent a secondary crash
  2. Mark the breakdown location only at night
  3. Provide lighting for the driver
  4. Increase fuel efficiency

Answer: A — Alert oncoming traffic and prevent a secondary crash

Warning devices are placed to alert oncoming traffic that there is a breakdown ahead, giving drivers enough time to slow down and maneuver safely. This creates a warning zone that reduces the risk of a secondary crash involving the stopped vehicle. They’re used in all lighting conditions, so the goal isn’t to light the driver’s path or to improve fuel efficiency.
