Most for-hire passenger carriers in California must be licensed by the CPUC before they can legally operate. This includes common carriers like limousines, airport shuttles, charter buses, and similar services.
CPUC issues: Charter-Party Carrier (TCP) permits and certificates – required for carriers that transport passengers by prearrangement and are compensated on a time/mileage basis.
Every Charter-Party Carrier (TCP) vehicle must display its TCP permit number (e.g. TCP ######) issued by the California Public Utilities Commission (CPUC) and it will typically be displayed on front/rear bumpers or side doors. The stickers/decals should look official, not handwritten or temporary.
How to check:
- Visit https://tcportal.cpuc.ca.gov/TCP/s/ and enter in Carrier Name, PSG#, or VCC# to verify that the carrier's license/permit is active and insurance is on file.
- Ask to see the TCP Certificate from the driver.
Before you engage a carrier, confirm they have the required liability and insurance filings on record:
CPUC requires all licensed carriers to have public liability and property damage insurance on file before operating.
Minimum liability requirements vary by vehicle size (e.g., up to $1,000,000).
Workers' compensation insurance may also be required if the carrier employs drivers.
Key distinction:
- Licensed TCP vehicle → Commercial auto insurance (min. $750,000)
- Unlicensed vehicle → Personal auto insurance (Excludes paid rides. If an accident occurs in an unlicensed vehicle, passengers may not be covered and they have to bear all expensive medical expenses by themselves).
Verification: Ask to see the Certificate of Insurance (COI) and confirm that it matches the CPUC's database status.
