If a stone thrown up by a passing vehicle shatters the front windshield into an opaque web of cracked glass while driving on an expressway, what should the driver do?

1. Accelerate to blow the shattered glass into the cabin
2. Turn on hazard warning flashers, maintain vehicle heading, decelerate smoothly, look through an unbroken section or side windows, guide the vehicle onto the emergency shoulder, and knock out a small sight hole if vision is zero
3. Slam the foot brake and yank the steering wheel
4. Close eyes and scream for assistance
