Who is required to stop at a level crossing with a red flashing light in the form of an arrow point to the right?

At a level crossing marked with a red flashing light in the form of an arrow pointing to the right, it is specifically indicating that traffic turning right must stop. This is based on German traffic regulations that prioritize safety at railway crossings. The flashing red light serves as a warning that a train is approaching, and vehicles turning right must yield to prevent any potential accidents.

It's important to recognize that while vehicles going straight or turning left may also be affected by these signals, the immediate requirement in this context is for right-turning traffic to stop. Therefore, understanding the correct interpretation of such signals is essential for road safety and compliance with traffic laws.
