How do I find a work-zone sign when I only know its name?
Search this collection for words such as shoulder work, road closed, or detour. Each result shows the sign code and links to its meaning, application notes, sizes, and downloads.
Are all temporary traffic control signs orange?
No. CA MUTCD Section 6F.01 distinguishes regulatory, warning, and guide signs. Regulatory signs retain the prescribed regulatory colors; orange is used for most TTC warning and guide signs, with exceptions. Fluorescent orange is permitted where orange is required.
Can this chart tell me the spacing or size for my project?
The sign pages provide size and application references. Installation choices depend on the sign, roadway, work activity, and applicable agency requirements. Confirm them using the current CA MUTCD and the approved traffic control plan.
Where are the PNG and PDF downloads?
