Difficulty: HardDriving in Adverse Weather and Low Visibility

When passing a high-profile commercial truck during sudden high-wind conditions on an open highway bridge, accelerating slightly is the recommended defensive driving maneuver to quickly escape turbulence created by the larger vehicle.

Answer: Answer

Answer

False. Drivers should slow down, maintain a firm grip on the steering wheel, and give high-profile vehicles extra clearance in strong winds rather than accelerating.
The statement is false because accelerating in severe crosswinds or turbulence compromises vehicle control, increases aerodynamic instability, and violates safe driving principles for adverse weather.

Step-by-Step Solution

1
Analyze the impact of high winds and aerodynamic turbulence when driving near high-profile vehicles.
High-profile vehicles block and deflect wind, creating sudden crosswind shifts and severe air turbulence for adjacent smaller vehicles.
Understanding vehicle dynamics in wind stream shadow zones is critical for safe vehicle control in adverse weather.
2
Evaluate the effect of accelerating during severe environmental hazards and turbulence.
Higher speeds reduce tire-road traction reserves and increase aerodynamic lift and steering instability.
Under basic speed law and safe driving practices, speed must be reduced during adverse weather conditions to maintain vehicle control.
3
Determine the proper defensive driving action.
The correct action is to slow down, maintain a firm two-handed grip on the steering wheel, and anticipate wind displacement rather than accelerating.
Slower speeds allow more time to react to lateral wind forces and keep the vehicle within its lane.
