What is the meaning of the following traffic sign?

- Refreshment station.
- Correct answer: First aid station.
- Private ambulance station.
- Ambulance parking only.
Why this is the answer
The correct answer in the official bank: First aid station.
The sign marks a first aid station, where you can get initial medical treatment. The bandaged hand stands for an injury and its treatment, so it is a sign for a station that gives first aid. Nothing in it suggests ambulance parking, a refreshment station or a private ambulance station.
