At minimum, a legitimate charter bus operator should hold active USDOT and MC (motor carrier) operating authority, commercial auto liability insurance meeting FMCSA minimums — $1.5 million for vehicles carrying 15 or fewer passengers, and $5 million for vehicles designed to carry 16 or more, including the driver — and documented driver qualification files including CDL verification and drug testing compliance.

You can verify a carrier's safety rating and operating authority directly through the FMCSA's SAFER system before booking — a legitimate operator will have no issue providing their USDOT number for you to check.
A low quote from an operator who can't produce a USDOT number isn't a deal — it's a liability risk.
Federal law requires any company operating vehicles designed to carry more than 15 passengers, including the driver, in interstate commerce to hold USDOT operating authority and meet minimum insurance requirements. Passenger carriers at that size are held to a $5 million minimum liability coverage threshold — well above standard commercial auto policies.
Beyond the paperwork, ask about the carrier's out-of-service rate and safety rating on the FMCSA's public SAFER database, and confirm drivers are subject to the same drug and alcohol testing program required of any interstate commercial driver.

What to ask before you book:
A provider that manages a vetted carrier network — rather than a single unverified operator — has already done this screening for you across every vehicle in the program.
