Explanation

Construction zones pose dangers both for drivers and for construction workers. Orange highway construction signs warn you to be careful when approaching construction zones. Some construction signs also provide guidance, such as the detour sign, or convey regulations, such as the worksite added penalty signs.

The manual’s construction signs are Detour, Detour Ahead, Worksite Added Penalties, Flagger Ahead (two versions), Right Lane Closed, Road Work Ahead, Work Crew Ahead and Worksite Speed Limit.

Example

You pass a Road Work Ahead sign and then a Worksite Added Penalties sign. The first warns you to be careful approaching the construction zone; the second conveys regulations for the worksite.

Common mistake
