Sharing the RoadStandalone practice
On a freeway, you drive in the lane next to a large truck, beside the middle of its trailer. You cannot see the truck driver's side mirrors. What does this tell you?
A is beside the middle of B’s white trailer. No visibility zone or move-ahead instruction appears in the question.
Correct answer: The truck driver cannot see you, so move ahead or drop back
Why
Large trucks, buses and motor homes have big blind zones beside and behind them. A truck driver who changes lanes or turns may not know that your car is there. The Washington Driver Guide tells you not to drive alongside large vehicles for long, and to keep a following distance that gives you a wide view of the road ahead.
