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

Answer: D — Shared lane for bicycles and cars.

A sign with a picture of a car and a bicycle indicates that the road is a shared lane for both bicycles and cars. This means that bicyclists and drivers should both use the same lane and be aware of each other to prevent accidents. Option A is incorrect as it only mentions bicycles and does not include cars. Option B is incorrect because it focuses on the bike lane ending, rather than the shared lane itself. Option C is incorrect because it forbids bicycles on the road, which goes against the purpose of shared lanes. Therefore, option D is the correct answer as it includes both bicycles and cars, and accurately reflects the meaning of the sign.
