Sudden wind gusts on highways:

  1. Generally affect only the movement of large vehicles.
  2. Only cause visibility problems.
  3. Can cause problems for all vehicles. ✓

Answer: C. Can cause problems for all vehicles.

Sudden wind gusts can cause problems for all vehicles, so keep firm control of the steering wheel and be ready to react.

Why this is the answer

The handbook calls high winds a driving hazard and notes they are especially risky for trucks, campers, and vehicles with trailers. That wording means larger vehicles are not the only ones affected. It also says gusts are unpredictable; if you are not holding the wheel properly when one hits, you can lose control. The handbook's advice to slow down, keep a firm grip, and stay alert applies to drivers generally, not just to big vehicles. That supports the answer that gusts can cause trouble for any vehicle.

Why the other answers are wrong

Remember it

Think "gusts grab every wheel": keep a firm grip and slow down rather than assuming only big rigs get pushed.
