If a large tractor-trailer is approaching an intersection from the left, what should you expect?

• A. It will turn wide and use part of your lane to complete the turn.
• B. It will stop quickly in your lane.
• C. It will stay in its lane.
• D. It will accelerate away to clear the intersection.

Answer: (A)

Tractors with trailers need more space to turn than passenger cars because of their long wheelbase. When they make a left turn, the front of the truck follows a tighter arc, while the rear trailer swings out wider. As a result, the truck may actually use part of the lane you’re in to complete the turn. So you should expect the vehicle to turn wide and occupy some of your lane temporarily. This is why the best response is to anticipate the wider turn and give the truck room.
