The G1b sign indicates a single-track railway level crossing with a flashing red warning light. It means you must be prepared to stop and should not enter the crossing unless the exit is clear and you can proceed without stopping on the tracks.
You must stop if the red lights are flashing, if barriers are present and lowered, or if instructed by railway personnel. Always ensure the exit of the crossing is clear before proceeding, even if the lights are not flashing or barriers are up.
A common mistake is assuming it's safe to cross simply because the red lights are not flashing or another vehicle has just crossed. Always check that the exit is clear and be aware that another train or tram could be approaching. Never enter if traffic ahead might trap you on the crossing.
Yes, France uses various signs for level crossings. Some have gates (like C1, C2), some have multiple tracks (G2a, G2b), and some are just warning signs without lights or gates (A1). The G1b specifically signifies a single track with active flashing red lights, demanding caution and readiness to stop.
