Is it true that a posted sign is required at the end of a construction zone to indicate the end of the zone?

A posted sign indicating the end of a construction zone is indeed required to inform drivers that they are exiting the temporary modifications to the driving environment. These signs serve a critical role in ensuring safety by signaling the transition back to normal driving conditions. This is important for maintaining traffic flow and preventing confusion among drivers who may need to adjust their speed or behavior after navigating through construction. Proper signage helps in reducing the likelihood of accidents as it provides clarity and promotes awareness of changes in road conditions. Thus, the presence of an end sign is a key element in effective traffic management and safety protocol in construction areas.
