CDL General Knowledge TestDriving SafelyHard
A commercial driver is preparing for a long haul through an area known for strong crosswinds. Which of the following precautions is MOST critical for maintaining control of the vehicle?
- AIncrease tire pressure to improve stability.
- BEngage the cruise control to maintain a steady speed.
- CIncrease awareness and be prepared to counter-steer.
- DMaintain a higher speed to push through the wind.
Show answer & explanationAnswer & explanation
Correct answer: C. Increase awareness and be prepared to counter-steer.
Strong crosswinds can push a large commercial vehicle sideways, requiring immediate corrective steering. Increasing awareness and being prepared to counter-steer is crucial for maintaining lane position and preventing the vehicle from being blown off course or into another lane.
Why the other options are wrong
- A. Increasing tire pressure beyond recommended levels can reduce traction and stability, not improve it in crosswinds.
- B. Cruise control should typically be disengaged in adverse conditions like strong crosswinds, as it can hinder quick driver reaction.
- D. Maintaining a higher speed increases the impact of crosswinds and makes the vehicle harder to control.
Driving in Crosswinds
Techniques for maintaining control of a commercial vehicle when exposed to strong winds blowing perpendicular to the direction of travel, which can push the vehicle sideways.
- Requires constant vigilance and steering correction.
- Trucks with high profiles are most affected.
- Reduce speed if winds are severe.
- Be aware of sudden gusts from openings (e.g., bridge ends).
Memory trick: Wind's a brute? Steer acute!
