What should be the first action taken in an advance warning area?

The first action to be taken in an advance warning area is to alert drivers about the upcoming work zone. This step is crucial because it prepares motorists for potential changes in driving conditions and ensures they have adequate time to respond appropriately. Proper signage and devices, such as warning signs and lights, are utilized to notify drivers of the presence of a work zone. This advance notice can significantly enhance safety for both the drivers and the workers in the area.

By informing drivers ahead of time, the likelihood of accidents due to sudden stops or erratic driving behavior is reduced. This proactive approach is an essential component of effective traffic control in work zones, fostering awareness and encouraging caution as vehicles approach the worksite.
