Answer: B — Keep as far as possible to the side

Keeping as far as possible to the side when a truck is approaching from the opposite direction is crucial for safety. Trucks are large and can create significant wind turbulence as they pass, which can affect smaller vehicles. By moving to the side, you reduce the risk of a collision and give the truck enough space, ensuring that both you and the truck can navigate the road safely. Maintaining distance not only helps in avoiding any potential accidents but also allows you to react better in case of unexpected situations. This approach is particularly important in narrow roadways or areas where visibility might be limited, as the size and speed of the truck can create a safer environment for everyone on the road.
