Rumble Strips (Work Zone)

Rumble strips have been installed across the lane ahead.

A California work-zone warning that temporary rumble strips have been placed across the travel lane to alert drivers approaching a hazard, such as a flagger station, lane closure, or queue. Expect a series of brief vibrations and noise as the tires cross the strips and slow to the posted condition.
