Zorluk: OrtaTire Failure and Blowouts

A commercial motor vehicle is traveling at highway speed on a dry, straight roadway when a front steer tire suddenly blows out, creating a heavy pulling force on the steering wheel. Which sequence of actions should the driver perform to safely maintain control and bring the vehicle to a stop?

  1. A
    Apply the service brakes firmly and immediately to bring the vehicle to a complete stop before steering control is lost.
  2. Hold the steering wheel firmly with both hands, stay off the brake pedal to let the vehicle coast down, and brake gently once slowed before pulling safely off the road.Cevap
  3. C
    Engage the engine retarder to maximum power while counter-steering aggressively toward the nearest roadway shoulder.
  4. D
    Execute rapid snub braking by pressing hard on the brake pedal and releasing it repeatedly until the vehicle reaches a walking pace.

Cevap

Hold the steering wheel firmly with both hands, stay off the brake pedal to let the vehicle coast down, and brake gently once slowed before pulling safely off the road.
The correct response to a tire blowout is holding the steering wheel firmly with both hands, staying completely off the brakes while the vehicle slows down naturally by coasting, and then applying gentle braking once speed is greatly reduced to move off the roadway safely.

Adım Adım Çözüm

1
Recognize the severe steering pull as a steer-tire blowout and establish two-handed physical control of the steering wheel.
Vehicle maintains straight tracking despite the strong pull caused by the blown tire.
A front-tire failure causes intense drag on one side, requiring significant physical effort on the steering wheel to keep the vehicle from swerving into adjacent lanes.
2
Stay completely off the service brake pedal and allow natural rolling resistance and aerodynamic drag to slow the vehicle down.
Vehicle decelerates steadily without inducing a skid or jackknife.
Braking when a tire fails places severe asymmetrical braking forces on the remaining intact tires, easily causing wheel lockup and loss of steering control.
3
Apply the brakes gently only after speed has dropped substantially, signal, and guide the vehicle completely off the travel lanes.
Vehicle stops safely in a secure location off the roadway.
Controlled gentle braking at low speeds avoids skidding while ensuring the disabled vehicle clears moving traffic.
