A “Detour” sign indicates that the normal route is temporarily changed and directs you to an alternate path because the usual road is blocked or closed (often due to construction, an accident, or some event). The detour sign is typically orange (since it’s associated with temporary traffic control) with black text or arrow.
What to do when you see a Detour sign:
Follow the arrow or instructions on the detour sign to navigate the alternate route. For example, it might say “Detour →” meaning you should turn in the direction of the arrow to stay on the temporary route.
You might see a series of detour signs guiding you around the closure. Often they’ll be labeled with a route, like “Detour A” or specific symbols, especially if there are multiple detours in the area.
Do not try to go through the closed road. If a detour is indicated, it means the road ahead is not passable for through-traffic. It could be physically barricaded or just unsafe.
Recognize that a detour might take you out of your way a bit. It might direct you off an exit you don’t normally take, through side streets, and then back onto the original road further down. It’s basically a temporary rerouting.
Pay attention for additional signs. Typically, there will be “Detour” signs at each turning point of the alternate route to guide you step by step. They might have arrows or street names.
If you’re using GPS, sometimes it will automatically reroute you once you deviate, but sometimes it might initially try to get you back to the closed road. In a case of an official detour, it’s usually best to follow the posted detour signs rather than your GPS if there’s any conflict, as the detour is designed to handle the traffic.
So, in short: A detour sign indicates a temporary route diversion. It’s telling you, “You can’t go the usual way; follow this direction to go around the closure and rejoin the road later.” Always follow detour signs to avoid getting stuck or entering dangerous areas. Once the road work or issue is resolved, the detour signs will be removed and you can take the normal route again.
