What does a sign with a picture of a bicycle and a car indicate?

Answer: C — Shared lane for bicycles and cars.

A sign with a picture of a bicycle and a car indicates a shared lane for bicycles and cars. This means that both bicycles and cars are allowed to use the same lane on the road. Option A is incorrect because it would indicate the end of a designated lane specifically for bicycles. Option B is incorrect because it would prohibit bicycles entirely from using the road. Option D is incorrect because it would prohibit passing for bicycles in a certain area, but not indicate a shared lane. It is important for drivers to pay attention to these signs to be aware and respectful of cyclists sharing the road.
