81. Detour
A detour, also called a diversion, is a temporary alternative route used when the normal road is closed, blocked or unavailable. Detours are commonly introduced during roadworks, accidents, public events, flooding or other disruptions. Drivers should follow the temporary direction signs carefully, reduce speed where necessary and expect unfamiliar roads, changed priorities or additional traffic along the alternative route.
