If the steering linkage suddenly fails or breaks on a moving passenger coach, what is the driver's primary emergency reaction?

1. Immediately release the accelerator, apply progressive brake pedal pressure (or emergency braking if collision is imminent), activate hazard flashers, and honk to warn other traffic
2. Slam the accelerator pedal to the floor to power through the steering loss
3. Turn off all exterior lights to conserve electrical power
4. Instruct all passengers to shift their body weight to the right side of the bus
