Sign 518 is an advance warning that the road ahead will narrow to a single lane in each direction. This usually happens due to roadworks, temporary obstructions, or specific road layouts. It’s your cue to prepare for reduced space and potential delays.
When you see sign 518, you should immediately ease off your accelerator and start to reduce your speed smoothly. Increase your observation, check your mirrors, and prepare to maintain a safe distance from the vehicle in front. Avoid sudden braking or acceleration.
A common trap is thinking this sign only means you need to slow down at the very last moment. The sign is an *advance* warning, meaning you should start adjusting your speed and observation *early*. Another trap is assuming it automatically means you have to stop; it indicates a change in traffic flow, not necessarily a complete halt.
Not necessarily. This sign warns of a change in road layout where traffic may have to proceed in single file. Depending on the specific situation (e.g., opposing traffic, temporary traffic lights), you might need to yield. The sign prompts you to be alert to these possibilities and to manage your speed and position accordingly.
You should not ignore the warning or wait until the hazard is right in front of you to react. Overtaking, accelerating hard, or changing lanes abruptly are also prohibited as they can reduce safety margins in potentially complex traffic situations. Focus on smooth, controlled driving.
Yes, supplementary plates (like distance plates or plates indicating the type of hazard) can provide crucial additional information. For example, a distance plate will tell you how far ahead the single file traffic restriction begins. Always pay attention to these if they are present.
