The SIG1 Red Signal is a crucial traffic sign that mandates a complete stop. You must halt your vehicle before the marked stop line, or before the signal itself if no stop line is present. Do not proceed until a green or otherwise permissive signal is displayed. If the red signal shows a contour arrow, the stop requirement only applies to the indicated direction, so always check for other signals governing different movements.
Learn the key details of the SIG1 - Red Signal road sign, including its function, what it communicates to drivers, and how it applies in real traffic situations in Sweden. Use this overview to understand the sign clearly and recognise it confidently during the Swedish driving theory exam.
A red traffic signal requires a complete stop before the stop line. If no stop line is marked, you must stop before the signal itself. You may not proceed until a permissive signal is shown. If the red signal includes a contour arrow, the stop requirement applies only to the direction or directions indicated by that arrow, meaning other movements may be controlled differently.
Stop. You must not pass the stop line, or if there is no stop line, you must not pass the signal.
Get clear, practical answers to the most common questions about the SIG1 - Red Signal 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.
The SIG1 Red Signal means you must stop your vehicle before the stop line or the signal itself. You are prohibited from passing this point until the signal changes to green or allows you to proceed. It’s a mandatory stop to ensure safety, especially at intersections.
If there is no visible stop line, the definition of the SIG1 Red Signal states you must stop before the signal itself. This ensures you don't enter the intersection or crossing area while the signal is red.
A contour arrow on the SIG1 Red Signal specifies the direction(s) to which the stop requirement applies. If an arrow points left, you must stop if you intend to turn left. Other directions might have different signal indications, so always look carefully at the entire signal setup.
While the red signal is active for your direction, the only allowed action is to stop your vehicle before the stop line or signal. You are not permitted to move forward until the signal shows green or another indication permits passage. Checking for traffic from other directions while stopped is also crucial.
A common trap is assuming that if you can see a green light for another lane, you can proceed. However, the SIG1 Red Signal applies specifically to your lane and direction. Always obey the signal controlling your path, and be aware of contour arrows that might limit the stop to specific movements.
You will most commonly see the SIG1 Red Signal at traffic light-controlled intersections, railway crossings, or anywhere traffic flow needs to be regulated to prevent collisions. It’s used to manage conflicting traffic streams and ensure pedestrian safety.
