What does a "Road Closed" sign imply?

A "Road Closed" sign indicates that all traffic is prohibited from proceeding along that particular stretch of road. This sign serves as a crucial warning to drivers that the road is not safe for travel, possibly due to construction work, natural disasters, or other hazardous conditions. The purpose of the sign is to ensure the safety of both the drivers and any workers or personnel who may be present in the area.

While there may be instances in which certain vehicles, like emergency vehicles, require access, the general rule conveyed by the sign is that no regular traffic should attempt to enter or continue down that roadway. Therefore, without exception, a "Road Closed" sign communicates a clear message that all types of vehicular traffic must turn around or seek an alternate route.
