The traffic sign "Traffic lane - two-lane in the direction of travel without oncoming traffic" indicates that the road ahead has two lanes that can be used for travel in one direction only. This sign is typically used on roads where there might be a central barrier or divide, ensuring that there is no oncoming traffic.

Drivers should be aware that they can safely change lanes within this area, and overtaking other vehicles is permissible. However, it is essential to exercise caution, as this setup can often be encountered in areas with heavy traffic. Always signal your intention to change lanes and check your mirrors for other vehicles before doing so.
