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

In German traffic rules, a red flashing light shaped like an arrow pointing to the right specifically signals that vehicles intending to turn right must stop. This is to ensure safety at level crossings (railway crossings) where a train may approach from that direction. Vehicles going straight or turning left are not required to stop because the warning applies only to the direction indicated by the arrow. Always obey such directional signals to avoid accidents and ensure smooth traffic flow.
