CDL Combination Vehicles TestDriving Combination Vehicles SafelyHard
A commercial driver is operating a combination vehicle under conditions of strong crosswinds. Which of the following adjustments is most critical for maintaining control?
- AIncreasing speed to improve vehicle stability.
- BMaintaining a firm grip on the steering wheel and making small, corrective steering inputs.
- CShifting to a higher gear to reduce engine RPMs.
- DActivating hazard lights to warn other drivers.
Show answer & explanationAnswer & explanation
Correct answer: B. Maintaining a firm grip on the steering wheel and making small, corrective steering inputs.
Strong crosswinds can push a combination vehicle, especially the trailer, significantly. A firm grip and small, continuous steering corrections (often into the wind) are crucial to counteract the wind's force and maintain lane position without overcorrecting.
Why the other options are wrong
- A. Increasing speed in strong crosswinds increases the effect of the wind and reduces reaction time, making loss of control more likely.
- C. Shifting to a higher gear might slightly reduce engine braking, but it does not directly address the lateral force of the crosswind and is less critical than steering control.
- D. Activating hazard lights might be done if the vehicle experiences severe difficulty, but it's not the primary action for maintaining control against crosswinds.
Crosswind Driving
When driving a combination vehicle in strong crosswinds, maintain a firm grip on the steering wheel and make small, continuous steering corrections to stay in your lane.
- Wind affects trailers more.
- Small, constant steering inputs.
- Reduce speed if necessary.
Memory trick: Wind blows? Grip tight, steer right (or left).
