What does a “road closed” sign indicate?

A "road closed" sign indicates that the road is not safe for any vehicle passage. This sign serves as a crucial safety measure, alerting drivers that the roadway is impassable due to various potential hazards, such as construction work, significant road damage, or other unforeseen circumstances that compromise the safety of the area. It is essential for protecting both motorists and workers by preventing traffic from entering an unsafe zone.

While local traffic may still be allowed in some closures, a "road closed" sign typically means that all traffic, including local, should find alternate routes for their safety. Construction work being conducted during specific hours or for a limited duration does not negate the clear message of the "road closed" sign, which emphasizes immediate safety concerns over logistical considerations.
