What should you do if your vehicle crashes into a body of water?

• Call 911 immediately.
• Roll the window down before the car sinks.
  Explanation:

  "If you crash into a pond, river, or other body of water, your vehicle will only float on the surface for 30–60 seconds. Roll the window down before the car sinks. If you can open the door, be aware that the car will immediately fill with water."
• Wait for the car to fill with water before exiting.
• Try to open the door first.
