Built for California Work Zone Professionals

MUTCDSignChart.com is designed specifically for contractors, traffic control drafters, permit coordinators, and project managers working in California — especially in Los Angeles County, the City of Los Angeles, and Southern California. All sign references are based on the CA MUTCD 2026 (effective January 18, 2026) and California-specific temporary traffic control requirements.

California traffic control signs must be verified against the current CA MUTCD 2026 (effective January 18, 2026), Caltrans sign specifications, Standard Plans, project documents, and local agency requirements.
