The traffic lane sign you are referring to is known as "Traffic lane sign - without oncoming traffic with integrated sign 274 2-lane in direction of travel." This sign indicates that the road has been designated as a one-way street, allowing traffic to flow in only one direction. It specifically informs drivers that they are entering a section of the road designated for travel in the specified direction, and there will be no oncoming traffic.

The integrated sign 274 indicates the number of lanes available for traffic in the indicated direction, which in this case, is two lanes. This is important for drivers to know as it helps them understand how to navigate the road safely and maintain proper distance from other vehicles.

In summary, this sign helps guide drivers in the correct direction while ensuring they are aware of the lane configuration, promoting safer driving conditions. If you have any other questions about German traffic rules, feel free to ask!
