Do you put your car in neutral if your acceleratior pedal gets stuck?

If you are traveling at freeway speed, (with the gas pedal stuck it might be faster) NO, unless you had to, to avoid hitting an object or person.

The reason is, you would blow your engine by stopping so suddenly at such a high speed.

If you do find your gas pedal stuck, first try to get it up with your foot. If that doesn't work push as hard as you can on the brake.

(just because the gas pedal isn't working doesn't mean the brake pedal isn't)

It WILL eventually bring your car to a stop, but slowly.

Pull over to a curb or roadside as you are braking, turn off the engine and get the gas pedal fixed.
