What does this traffic sign indicate?

This traffic sign indicates that drivers must proceed straight ahead. In Germany, this sign is known as a "Rechtsfahrgebot" when it appears in conjunction with other signs. It means that vehicles are required to continue forward and not make any turns. This helps maintain traffic flow and ensures safety by guiding drivers on the correct path at intersections or road sections where multiple directions might be possible. Understanding and following this sign is essential for avoiding potential accidents and ensuring compliance with road regulations.
