What do you have to be aware of in this situation?

You answered correctly. The sign indicates that in 200 meters, the left-hand lane will become narrower, so you need to be ready for this change in road conditions. Additionally, the sign shows a width restriction for vehicles, which means you must consider if your vehicle, including its exterior mirrors, might exceed the specified maximum width. Knowing both points helps you drive safely and be prepared for reduced space or possible need to merge. Answer 3 would be incorrect because the narrowing does not last for 200 meters; it starts in 200 meters. Always watch for these signs and check your vehicle’s width before entering restricted lanes.
