While approaching a rain-slicked highway construction zone, abrupt application of the service brakes locks the drive wheels and causes the rear of the vehicle to slide outward. In what sequence should the driver execute the recovery steps to regain directional stability?
- 1Release the service brakes completely to allow the locked drive tires to resume rolling and regain lateral grip.
- 2Turn the steering wheel quickly in the direction the rear of the vehicle is sliding.
- 3Counter-steer in the opposite direction immediately as the vehicle begins to straighten.
- 4Center the steering wheel and stabilize vehicle path within the travel lane once full traction is restored.
Cevap
Release service brakes immediately, turn the steering wheel in the direction of the skid, counter-steer as the vehicle begins to straighten, and center the steering wheel once aligned.
The established CDL recovery procedure for a drive-wheel braking skid requires eliminating the cause of wheel lockup first by releasing the brakes, steering into the skid direction to re-establish alignment, counter-steering rapidly to arrest over-rotation, and centering the steering wheel once stable rolling traction is restored.
