If your car's engine suddenly shuts off while driving, you should:

• Apply the brakes firmly and come to a complete stop as quickly as possible
• Shift to neutral, turn on hazard lights, and try restarting the engine while the car is still moving
  Explanation:

  "If your engine suddenly shuts off while driving, shift to NEUTRAL, move out of traffic, and turn on hazard lights. Avoid braking. Try to restart the engine while coasting. If it starts, shift to drive and proceed. If it doesn't, pull over, turn on hazard lights, raise the hood, and seek help. Use a cell phone if available."
• Maintain your speed and steer to the side of the road when possible
• Pull over immediately and turn off the engine
