Curve Left (Work Zone)
The roadway curves to the left through the work zone ahead.
Work-zone advisory warning of a gradual leftward curve in the realigned travel path. Less abrupt than a turn warning but still requires drivers to slow below the highway speed, especially where temporary barriers, drums, or cone tapers narrow the available lane.
