An unladen straight truck traveling at 45 mph on a wet two-lane highway encounters a sudden hazard, and the driver presses the service brake pedal too hard, locking the rear wheels and initiating a lateral fishtail slide to the left. What is the correct sequence of actions the driver must take to regain directional control?
- ASteer to the right away from the direction of the slide while pressing harder on the brake pedal to bring the vehicle to an immediate halt.
- BActivate the secondary engine retarder switch to maximum braking power while holding the steering wheel strictly centered.
- Release the brake pedal immediately to restore rolling traction, steer to the left in the direction of the skid, and counter-steer as the vehicle aligns.Cevap
- DMaintain heavy braking through the curve and apply aggressive throttle only after the truck leaves the slippery section.
Cevap
Release the brake pedal immediately to restore rolling traction, steer to the left in the direction of the skid, and counter-steer as the vehicle aligns.
Releasing the brake pedal allows the locked drive tires to resume rolling, which is essential to restore lateral cornering grip. Steering in the direction of the slide aligns the front wheels with the vehicle's movement, and subsequent counter-steering prevents the vehicle from snapping into a secondary skid in the opposite direction.
Adım Adım Çözüm
Anahtar Kavram
Drive-wheel braking skid recovery requires releasing the brakes to restore rolling traction, steering in the direction of the skid, and counter-steering to prevent a secondary skid.
