Your vehicle is stopped on or beside the road. Which statement about warning approaching traffic is correct?

Correct answer: When a hill or curve hides your vehicle from sight within 500 feet, the rearmost triangle should be set farther back.

Answer options

  1. AAs long as your taillights are on, drivers coming up from behind have all the warning they need.
  2. BYou can leave the warning triangles in the cab unless you expect to stay stopped for 30 minutes or more.
  3. CWhen a hill or curve hides your vehicle from sight within 500 feet, the rearmost triangle should be set farther back. Correct

Why

Drivers need time to react, so if a hill or curve means they cannot see your stopped vehicle from 500 feet away, the rearmost triangle has to go farther back along the road. Triangles must be set out within 10 minutes of stopping, however long you plan to stay, and taillights alone are not a dependable warning.

Tip When a hill or curve limits the view, the rear triangle may need to go anywhere from 100 to 500 feet behind your vehicle.
