What is indicated by one or two flashing or alternating red lights placed on a signaling device?

Question

DentroTest · Accepted Answer

The correct answer is that they temporarily prohibit passage. According to traffic regulations, one or two flashing or alternating red lights indicate that the road is temporarily closed to traffic. This signal implies a mandatory stop before passing the light. They are commonly found in specific high-risk situations, such as: Level crossings (railroad crossings). Entrances to drawbridges or ferry terminals. Exits for fire-fighting vehicles. Areas where aircraft fly at low altitudes. It is important not to confuse them with a flashing yellow light (which requires caution) nor to think that they oblige you to stop 'at all times,' as the prohibition is effective only while the lights are flashing.
