Detour signs are used to direct traffic away from construction sites or potentially dangerous road conditions. A detour sign may be temporary or long-term. While a temporary sign may reflect regular road work, there may be factors such as mudslides that cause a road to be closed for several months or even years. Detour signs, like other traffic warning signs, must comply with government regulations at all levels and be easy to read for drivers, even from a distance. Providing adequate warning is an important key to reducing accidents caused by stress, distractions, or confusion.
