You have been involved in a road accident as the driver of the vehicle. After administering first aid to the injured persons, are you allowed to leave the scene of the accident before the arrival of the police?

No, you are not allowed to leave the scene of an accident where there are injured people. According to Art. 44 of the Road Traffic Act, the driver is obliged to remain at the scene of the incident until the police arrive. The only exception is leaving to call the emergency services, but even then, you must return immediately.
