What's the emergency that you would consider driving over downed power lines? Turn around and go back to an open area and park. If you're headed home, tell Honey you'll be late. If you're going to work, tell them you'll be late or you're sick. If you're bleeding heavily or your labor contractions are less than two minutes apart, you shouldn't be driving, anyway.

If you insist on driving over live power lines, your car is wearing studded tires, and you survive, be sure to post here and tell what happened to the tires. I've always wondered what would happen.

But this looks like some good advice:

"If you must drive, be watchful for downed power lines, tree limbs, and general blockages in the road. Never drive over a downed line with your car. If the car has made contact, your car could become energized. Stay in your car and roll your window down to call for help. You can also use a cell phone to dial 911.

"... If the car has made contact and catches on fire, you have two problems. Don’t panic! You must get out of the car in this instance. The way you exit the car will determine whether you live to tell about it. Open the car’s door and stand on the floorboard of the car. Jump away from the vehicle with both feet together as far as possible. Don’t hang on to any part of the car during the jump, including the door handle. If you do, you’ll likely become the path to ground from the energized car to the street below. Remember, your car has four rubber wheels and is essentially insulated from the ground. When you just step out out the vehicle while touching it, you have completed the circuit.

"De-energized Power Lines - Although you can see that the power lines are down and the power is out, don’t think that it is safe to move a downed line. These power lines could become re-energized at any time! Never assume anything when working around power lines. Instead, assume that they are live and that electrocution dangers exist."
