Merge (Right, Work Zone)

Traffic from the right merges with your lane ahead in the work zone; share space and adjust speed.

Advance warning that a separate travel lane joins your lane from the right within a work zone. Check your mirrors and blind spot, adjust speed to allow merging vehicles to enter, and be ready to share the lane through the construction area.
