The SIG6 sign indicates a red acoustic signal, emitting a slow pulse. This signal is crucial for pedestrians, especially at crossings involving vehicles, cycle paths, or rail/tram tracks. When you hear this slow pulsing sound, it means you must not enter the crossing area. If you are already on the crossing when the signal activates, continue to the other side, or stop at a safe refuge if available.
This specific road sign, the SIG6 Red Acoustic Signal with a slow pulse, indicates a critical warning for pedestrians. Recognizing its meaning is vital for safe passage and successful theory test revision, ensuring you understand when and how to cross safely.
A red acoustic signal with a slow pulse frequency is intended primarily to guide pedestrians, often at crossings that involve vehicles, cycle paths, or rail or tram tracks. When this signal is active, it is forbidden to step onto the carriageway, a cycle path, or a railway or tramway crossing. If you are already on the carriageway or cycle path when the signal changes to red, you must continue to the other side to clear the crossing. If there is a refuge island or similar safe waiting area in the middle, you should stop there instead of completing the entire crossing at once.
Do not enter the carriageway, cycle path, or rail or tram crossing. If you are already crossing when it turns red, continue to the other side, or stop on a refuge if available.
Get clear, practical answers to the most common questions about the SIG6 - Red Acoustic Signal (Slow Pulse) road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the Swedish driving theory exam in Sweden.
As a driver, the SIG6 signal is primarily an auditory cue for pedestrians. However, it alerts you to a crossing situation where pedestrians may be present or about to cross. Be extra vigilant and prepared to stop if pedestrians are indicated by the signal, especially at complex crossings with cycle paths or tram lines.
When the SIG6 red acoustic signal with a slow pulse sounds, pedestrians must not step onto the carriageway, cycle path, or rail/tram crossing. If they have already started crossing, they should proceed to the other side. If there's a refuge island, they should stop and wait there until it's safe to continue.
The main exception relates to those already on the crossing when the signal turns red. They are permitted to continue to the other side. Also, if a refuge island is present, it is considered safer to wait there rather than completing the full crossing immediately if traffic conditions are not clear.
The slow pulsing red acoustic signal (SIG6) is designed to provide an auditory cue for pedestrians, enhancing accessibility and safety, particularly for visually impaired individuals. It reinforces the visual red signal at crossings, ensuring that people are aware it is unsafe to cross.
Yes, the SIG6 signal is used at crossings where there are rail or tram tracks. The acoustic signal, along with any visual signals, indicates when it is unsafe to enter these specific types of crossings due to potential conflict with moving trams or trains.
