What do you do when you see this traffic sign?

This traffic sign warns that the road ahead narrows. According to German traffic rules, when you see this sign, you should reduce your speed to maintain control and be prepared for changing traffic conditions. Additionally, you must refrain from overtaking because the narrower road makes it more dangerous to pass other vehicles safely. There is no requirement to always stop before the road narrows; stopping is only necessary if traffic conditions demand it. Understanding this rule helps you anticipate hazards and drive safely through constricted road sections.
