You see this traffic sign. What must you reckon with?

The traffic sign you're seeing indicates situations related to oncoming traffic. Specifically, it signifies that you must expect oncoming traffic on a narrow road.

1. **Oncoming traffic**: This is crucial as it alerts drivers to be cautious due to limited space for passing vehicles.
2. **Dazzle from oncoming traffic at night**: It's essential to be aware that oncoming vehicles may dazzle you with their headlights, especially at night, necessitating extra caution.

Both aspects are important for safety, helping you navigate potentially hazardous conditions when space is limited. Understanding this sign ensures you are prepared for the challenges of driving on narrow roads with opposing traffic.
