This FAQ strengthens your understanding and supports accurate decision making for the German driving theory exam in Germany.
The 'Arbeitsstelle' sign (123) is a warning that there are roadworks ahead. It means you need to be extra vigilant, reduce your speed, and be prepared for changes in road layout or traffic flow. Always be ready to adapt your driving behaviour before you encounter the actual work area.
You must not treat the warning as optional or wait until you're directly in front of the hazard. Overtaking, accelerating rapidly, or following too closely are prohibited, especially if visibility is reduced, the road surface is unstable, or there's conflicting traffic. Never assume the danger is confined only to the sign's immediate location; it could extend further.
Upon seeing sign 123, you should proactively reduce your speed to maintain full control well before reaching the work zone. Scan the road ahead and around you for potential risks, increase your following distance from other vehicles, and be prepared to brake smoothly. Ensure your lane position is safe and your speed is appropriate for the conditions.
A common exam trap is assuming the sign only applies to the exact spot where it's placed. Remember that the hazard might start shortly after the sign. Another trap is not factoring in other elements like supplementary plates, road markings, or traffic lights which modify the basic warning. Always combine the sign's message with all other available information.
No, the 'Arbeitsstelle' sign (123) is a warning sign, not a command to stop. It signals that conditions ahead may require you to slow down, change lanes, yield to other traffic, or be more cautious. Whether you need to stop depends on the specific situation ahead, indicated by other signs, signals, or the presence of workers and machinery.
