What This Sign Means
The California application of the Flagger warning sign, reflecting CA MUTCD and Caltrans flagging practice, sizing, and fluorescent orange sheeting.
California Temporary Traffic Control Use
California applies the flagger symbol warning with Caltrans flagging procedures, commonly paired with BE PREPARED TO STOP and sized per Caltrans specifications.
Common TCP Context
- Caltrans and local-agency flagging operations
- Paired with BE PREPARED TO STOP
- Sized per Caltrans sign specifications
California Size Requirements
Typical minimum: 48" × 48" on conventional roads; 60" × 60" on expressways and freeways.
Sizes are CA MUTCD minimums and vary by roadway classification and speed. Verify against the CA MUTCD 2026 (CA MUTCD Part 6 (Temporary Traffic Control), Chapter 6F; warning-sign design in Part 2C), Caltrans sign specifications, and the reviewing agency.
Common Placement on a TCP

CA MUTCD reference: CA MUTCD Part 6 (Temporary Traffic Control), Chapter 6F; warning-sign design in Part 2C.
Los Angeles Area Usage Notes
In Los Angeles, this sign must conform to CA MUTCD 2026. Work in City of LA right-of-way is reviewed by StreetsLA and the Bureau of Engineering (BOE); state highways in LA County are permitted and reviewed by Caltrans District 7; county roads are permitted by LA County DPW. Sizes, retroreflectivity, and placement must meet CA MUTCD minimums — local agencies may require larger signs based on roadway class, speed, pedestrian volume, and proximity to schools or transit.
Common Plan Review Comments
- Sign not shown at the correct advance distance for the posted speed.
- Advance warning sign missing or out of sequence on the TCP.
- Wrong size specified for the roadway classification (conventional vs. expressway).
- Sign sheeting / retroreflectivity class not noted on the plan.
Plan Review Notes
Confirm California flagging-station signing, sizing, and sheeting meet CA MUTCD and Caltrans practice. Public Ready reviews California flagging signs.
