What does this traffic sign indicate?

This traffic sign is a mandatory direction sign, indicating that you may only drive straight ahead. It means turning left or right is prohibited at this point. This rule is important for maintaining traffic flow and safety in certain situations, such as in one-way streets or areas where turning could disrupt traffic or cause danger. It does not give you priority over oncoming traffic, nor does it necessarily mean you are on a one-way road; it simply restricts your movement to straight ahead at this location.
