During expressway transit, a commercial driver experiences heavy vehicle vibration followed immediately by rear fishtailing, indicating a sudden rear dual blowout. Which sequence of actions is the safest and most effective procedure to maintain vehicle stability and bring the combination to a stop?
- Maintain a steady grip on the steering wheel, stay off the service brakes entirely, allow the vehicle to decelerate naturally by coasting, and gently brake only after slowing down to pull off the roadway.Cevap
- BDepress the service brakes firmly and immediately to stop the vehicle within the travel lane before rim damage or complete tire separation occurs.
- CEngage the trailer hand valve immediately to stretch the combination unit while counter-steering rapidly against the direction of the rear sway.
- DDownshift rapidly through multiple transmission gears and use snub braking technique to quickly arrest vehicle momentum.
Cevap
Maintain a steady grip on the steering wheel, stay off the service brakes entirely, allow the vehicle to decelerate naturally by coasting, and gently brake only after slowing down to pull off the roadway.
When a tire fails, the essential rule is to stay off the brakes. The driver must maintain a steady grip on the steering wheel to keep the vehicle travelling straight, release the accelerator, allow the combination to decelerate naturally through aerodynamic and rolling resistance, and apply the brakes lightly only after speed has dropped significantly to maneuver safely onto the shoulder.
