The Traffic lane sign indicating "without oncoming traffic" with the integrated sign 253 3-steep in the direction of travel informs drivers that the lane ahead is designed for vehicles traveling in a particular direction, and there will not be any oncoming traffic. This is typically used in situations such as one-way streets or roads where traffic has been regulated to flow in one direction only.

The added integration of "3-steep in the direction of travel" likely refers to a specific indication regarding the incline or decline of the road, suggesting that drivers should be aware of the steep gradient as they approach this lane.

This sign helps ensure safety by clearly marking lanes and informing drivers about the lane's direction and road conditions, helping to prevent head-on collisions and improve the overall flow of traffic.
