Question

If a person can't swim/float, are they automatically dead if their car goes over a bridge?

Answer 1

depends if someone saves them or not.

Answer 2

well it takes awhile to sink and there could be another person in the car or a bystander that helps them so no they aren't automatically dead.

Answer 3

Is the bridge over water?

Actually, it takes a few minutes for a car to sink after it hits the water, so you'd stand a good chance of being rescued or at least making it out of the car.
