If you're in a car or bus accident involving a power line, your first impulse might be to jump out of the vehicle. But the safest thing to do is STAY IN YOUR VEHICLE TILL HELP ARRIVES.
Why? Because the metal parts of the car might be energized. If you touch the outside of the car and the ground at the same time, you could get electrocuted. BCES will come quickly to move the power line safely away.
If you abslutely must leave the vehicle, hop out with your feet together, making sure to land on both feet. Be very careful not to touch the car and the ground at the same time. Continue carefully hoppng with your feet together in short hops until you're as far away as possible.
