What must you anticipate in this situation?

You answered correctly. In this situation, you must anticipate that your vehicle may be forced to the left when exposed to strong side winds, especially as indicated by the windsock. Additionally, when entering the wind-protected area beside the truck, your car can be suddenly pushed rightwards because the force of the wind changes. Recognizing these wind effects, especially near large vehicles and on open roads, is important for maintaining safe control of your vehicle. Always drive carefully when passing trucks in windy conditions.
