In a work zone to give advance warning of lane closings, construction areas, and workers ahead, the type of sign posted is:
C. Orange, diamond-shaped
These signs are specifically designed to alert drivers of upcoming changes in the road conditions, lane closures, construction zones, or the presence of workers on or near the road. The orange, diamond-shaped signs are standardized to ensure uniformity and clear communication to drivers on the road.
These signs play a crucial role in promoting safety by providing drivers with essential information well in advance, allowing them to adjust their speed, merge correctly, and navigate through the work zone without causing accidents or delays. Therefore, it's important for drivers to pay close attention to these signs and follow any instructions provided to ensure the safety of both themselves and the workers in the construction zone.
