C31 Traffic Control Contractor License Lookup

Use this page when you need a California C31 license lookup, a list of licensed traffic control contractors, or a quick screen before assigning traffic control work to a sub. Each row links to a contractor profile with CSLB status, workers' comp, bond, federal records, and permit checks.

California has 477 CSLB C31 license records for traffic control contractors. 96% currently hold active licenses and 15.3% have at least one federal compliance record. SiteVetter checks CSLB status, SAM.gov debarment, DOL wage violations, OSHA safety citations, EPA environmental records, and building permits in seconds.

What to Check for C31 Traffic Control Contractors

  • Verify the contractor license is active and in good standing
  • Request proof of insurance and bonding
  • Get at least 3 written quotes before selecting a contractor
  • Check federal databases: SAM.gov, OSHA, DOL, and EPA records
  • Confirm bond: California requires $25,000+ contractor bond (SB 607)

Why Federal Records Matter for Traffic Control Work

For traffic control work, 15.3% of licensed contractors have federal records that a standard CSLB license check would not reveal. SiteVetter's 6-source lookup gives GCs a faster way to compare subs before bid award, onboarding, or renewal review.

Data sourced from California Contractors State License Board and federal databases. Updated weekly. For official verification, check directly with CSLB.
