When stopping along the roadway to rest, what precautions should you take?

• Stop in a secure area or as far off the highway as possible if security isn’t available
• Lock all doors, turn off the engine, and turn on parking lights
• Allow some outside air but keep windows closed enough to prevent entry
• All of the above
  Explanation:

  "If you need to stop and rest along the roadway, find a secure or well-lit area and park as far off the highway as possible. Lock all doors, turn off the engine, and keep windows slightly closed for air but secure against entry. Turn on parking lights and avoid using other electrical equipment. After resting, get out and walk briefly to fully wake up before driving. Avoid sleeping for more than 20 minutes, as it can cause grogginess."
