The Short Answer

Charter bus operators in California must be licensed by the CPUC, comply with safety regulations including vehicle inspections and driver qualifications, and carry minimum liability insurance of $5 million.

What the Law Says

California law imposes strict licensing, safety, and operational standards on charter bus operators to protect passengers and the public.

Charter bus operators in California must obtain a Certificate of Public Convenience and Necessity (CPCN) from the California Public Utilities Commission (CPUC) before offering service. This applies to any motor carrier transporting passengers for compensation on a charter or contract basis.

Operators must maintain vehicles in safe operating condition, with inspections required at least every 12 months by a CPUC-certified inspector. Drivers must be at least 21 years old, hold a valid commercial driver’s license (CDL) with passenger endorsement, and pass a Department of Transportation (DOT)-required physical examination.

Liability insurance is mandatory: charter bus carriers must carry a minimum of $5 million in combined single-limit liability coverage for bodily injury and property damage arising from each accident.
