Why are advance warning signs important in a TTC setup?

Advance warning signs play a critical role in temporary traffic control setups as they specifically alert drivers to the presence of upcoming work zones. This early notification is essential for allowing drivers to adjust their speed, be more cautious, and prepare for any changes in traffic conditions.

The effective use of advance warning signs enhances safety not only for motorists but also for workers in the construction zone by promoting awareness of the changing road environment. Drivers need to know in advance that they are approaching a work zone so they can react appropriately, thereby reducing the risk of accidents.

While other choices touch on aspects related to traffic management and construction, they do not capture the primary purpose of advance warning signs, which is to provide critical information that prepares drivers for the conditions they are about to encounter.
