What role do advance signs play for drivers approaching a work zone?

Advance signs play a crucial role in informing drivers about the conditions they will encounter as they approach a work zone. These signs are designed to provide vital information, such as the possibility of upcoming lane changes, road closures, or other changes in driving conditions. By alerting drivers to potential hazards or adjustments they need to make, advance signs help enhance safety for both road users and workers in the construction zone.

This proactive communication allows drivers to prepare in advance, which can lead to smoother transitions and reduce the likelihood of accidents. Different types of advance signs can convey various messages, including reduced speed limits, detours, or the presence of workers on the road. The clarity and visibility of these signs are essential for maintaining safety and efficiency in the work zone.
