The sign "Diversion table short traffic diversion - without oncoming traffic 1-lane to the left" indicates a temporary diversion in the road due to construction or an obstruction. This sign specifically informs drivers that they need to merge to the left to continue on the road, and it’s designed for situations where there is one lane for alternate traffic, meaning there won't be oncoming vehicles in that lane.

You should prepare to naturally transition to the left lane and be cautious of any other vehicles that may be merging or transitioning. Always follow any additional directional signs or instructions provided for the detour, and maintain safe driving practices to ensure everyone's safety on the road.
