The sign you referred to is known as the "Deflection board - without oncoming traffic, 2-lane deflection, 1-lane on the shoulder."

This traffic sign indicates a situation where the road layout is changing, and it guides drivers on how to navigate through the area safely. Specifically, it means that there is a deflection in the road, directing traffic to the side, and there is no oncoming traffic in this section.

Here's what it implies for drivers:

1. **Deflection**: The road is not straight ahead; the driver should follow the direction indicated by the sign to avoid an obstacle or navigate a bend.

2. **2-lane deflection**: The road continues with two lanes, allowing for a smoother flow of traffic as you navigate the deflection.

3. **1-lane on the shoulder**: It indicates that there is a designated lane on the shoulder where vehicles may operate, which might be useful for emergency stops or if traffic is congested.

Drivers should be cautious and adhere to the indicated path to ensure safety. Always follow the sign's guidance to maintain control of the vehicle and avoid accidents.
