The I9b sign is a Portuguese advance direction sign indicating that you are approaching a level crossing. The slanting bars show your distance from it, with each bar representing 100 meters. It prompts you to prepare for a level crossing and make necessary route or lane decisions well in advance.
Upon seeing the I9b sign, you should immediately start preparing for a level crossing. This means observing the road ahead, checking your mirrors, and planning your lane position. You should be ready to slow down, stop, or yield depending on signals and the presence of a train, as indicated by other signs or traffic signals at the crossing itself.
The slanting bars on the I9b sign are visual cues indicating your proximity to a level crossing. Each bar represents a distance of 100 meters. As you get closer to the crossing, you will see fewer bars, or the bars will be positioned differently, indicating you are within 100m, 200m, or 300m of the level crossing.
A common exam trap is not understanding that the I9b sign is an advance warning. Learners might think they need to stop immediately. The sign requires early preparation and route planning, not necessarily immediate braking, unless other conditions (like a red light or approaching train) dictate it. Always interpret it in conjunction with other traffic signals and road markings.
No, the I9b sign itself does not mean you must stop. It is an advance warning sign indicating that a level crossing is ahead. You should only stop if there is a red light, a signal indicating an approaching train, or if a train is indeed crossing. The sign helps you to prepare and choose the correct lane or adjust your speed well before you reach the actual decision point at the crossing.
