About Instructions from competent persons: who, and what rank: which statement is WRONG?
Only competent and recognisably identifiable officials, marechaussee, customs officers or traffic controllers are binding.
Road users must stop when an escort of a rail vehicle shows a stop signal with sign F10, a red flag or a red lamp — this competence is separate from the police.
Instructions take precedence over traffic signs and traffic rules, including a green traffic light.
A traffic warden (verkeersbrigadier) may make you stop anywhere on the road, not just at a crossing point for children.
