The police officer gives the traffic instructions by his body position and with specific arm movements. A raised arm means: The drivers waiting at the intersection are not allowed to continue driving, previously locked drivers should prepare for the onward journey. For this, the policeman spreads his arms from the body or puts them on the body, depending on the instructions. If the police officer stands with his chest to the driver, the driver must stop. If the police officer stands sideways and the driver sees his profile, the driver may continue driving at a moderate speed.
