What is required at the beginning and end of a work zone?

At the beginning and end of a work zone, warning signs are crucial for alerting drivers about upcoming changes in traffic conditions and potential hazards. These signs inform motorists that they are entering a construction or maintenance area, which may require them to reduce speed, be cautious, and be prepared for unexpected scenarios such as lane shifts or workers present in the roadway.

The importance of warning signs lies in their ability to communicate critical information to drivers well in advance, allowing them the time necessary to adjust their speed and driving behavior accordingly. By ensuring that drivers are aware of the work zone ahead, these signs help to enhance safety for both the drivers and the workers on site.
