What should you do when a law enforcement officer approaches your vehicle during a traffic stop?

• Keep all windows closed for safety.
• Roll down the corresponding window so you and the officer can communicate better.
  Explanation:

  "After pulling over your vehicle, the officer may approach either side of the vehicle. When the officer approaches the vehicle, remember to lower the corresponding window so you and the officer can better communicate."
• Open the sunroof to provide better visibility.
• Keep all doors locked until the officer instructs otherwise.
