Not all traffic control companies are the same. Choosing the wrong provider can mean rejected permit applications, stop-work orders, project delays, and increased liability exposure. Here are the 7 questions every contractor should ask before hiring a traffic control company in Southern California.

1. Are They MUTCD and CA Supplement Compliant?

California uses both the federal Manual on Uniform Traffic Control Devices (MUTCD) and the California Supplement. Any traffic control plan or work zone setup must comply with both. Ask your provider directly — if they can’t clearly explain what the CA Supplement requires, look elsewhere.

2. Can They Provide a PE-Stamped Plan?

Caltrans projects and many complex city jobs require a Professional Engineer (PE) stamp on your traffic control plan. Not every TCP company has access to a PE. If your project touches a state highway or requires Caltrans review, confirm upfront that PE-stamped plans are available.

3. Do They Know Your Specific Agency’s Requirements?

Caltrans District 7 (LA) has different requirements than District 12 (Orange County). LADOT has different standards than LA County DPW. A traffic control company with local experience knows what each reviewer looks for — and that means your plans get approved the first time, not after multiple revision cycles.

4. What Is Their Turnaround Time?

For planned projects, 48–72 hours is a reasonable standard. For emergency utility work, you need same-day capability. Ask specifically:

• What is the standard turnaround for a simple lane closure TCP?
• Do you offer rush or emergency service?
• What happens if there’s a revision request from the agency?

5. Are They DBE or SBE Certified?

If your project is publicly funded (city, county, state, or federal), you likely have Disadvantaged Business Enterprise (DBE) or Small Business Enterprise (SBE) participation requirements. Using a certified provider like Safe Pass Traffic counts toward those goals — making your bid more competitive and your project compliant.

6. What Do Their Past Clients Say?

Ask for references from projects similar to yours. Better yet, check their Google reviews. Look specifically for comments about:

• Plans getting approved without revisions
• Responsiveness and communication
• Handling of emergency or last-minute requests
• Knowledge of local agency requirements

7. Are They Properly Insured?

Your traffic control provider should carry adequate general liability insurance, and for field work, workers’ compensation. Ask for a certificate of insurance naming your company as additional insured on the GL policy. Caltrans requires the State of California to be named as additional insured on any encroachment permit work.

Red Flags to Watch For

• No PE on staff or on call — fine for simple work, a problem for Caltrans jobs
• One-size-fits-all plans with minimal customization
• Slow response times or hard to reach by phone
• Can’t provide references from similar projects
• No knowledge of your specific agency’s submittal requirements
