How would high winds affect his journey?

Explanation: • Prolong the journey as he would have to slow down to control the vehicle: No, although a possible correct answer, this is not the 'best answer' in this selection.
• Have no effect on the vehicle: No, clearly any significant wind would have some effect.
• Only affect the trailer and not the tractor unit: No, anything that affects the trailer must also have some effect on the tractor unit since the two are connected.
• They would make it harder to keep the vehicle in the lane: Yes, as they would be exerting a force on the side of the vehicle.
