What if a power line comes down onto my car or I didn’t see it until I’ve driven into it?

If you are in your car and it is in contact with the downed line, stay in your car. Tell others to stay away from your vehicle.

If you must leave your car because it’s on fire, jump out of the vehicle with both feet together and avoid contact with the live car and the ground at the same time. This way you avoid being the path of electricity from the car to the earth. Shuffle away from the car.
