What does the sign warning of a detour indicate to drivers?

The sign warning of a detour indicates to drivers that they need to follow a temporary route due to some sort of obstruction or construction ahead. This means that the normal path of travel is not accessible for a particular distance or road section, and an alternative route has been established for drivers to safely navigate around the issue. By obeying this signage, drivers can effectively maintain traffic flow and minimize delays caused by the road conditions that necessitated the detour.

Other responses do not align with the purpose of a detour sign. Increasing speed could lead to unsafe conditions, stopping and waiting would not help drivers reach their destination, and turning around would be impractical when a designated alternative route is already in place for navigation. Understanding detour signage is essential for safe and efficient travel.
