Everything you need is public and free
Interstate passenger carriers in the United States are regulated by the Federal Motor Carrier Safety Administration, and nearly every meaningful safety fact about a bus company is published in databases anyone can search. Five minutes of checking is the highest-value diligence in the entire booking process.
You need one piece of information to start: the operator's USDOT number. Any legitimate carrier provides it immediately — it is usually printed on the side of the vehicle and listed in the footer of their website.
Step 1 — Look up the carrier on SAFER
Search the USDOT number on the FMCSA's SAFER Company Snapshot. Confirm four things: operating status is ACTIVE (not 'out of service' or 'inactive'), the entity type includes passenger carrier authority, the fleet size and driver count are consistent with the company's claims, and the address matches the business you are talking to.
An 'out of service' status means the carrier is legally prohibited from operating. If you see it, stop there — no price is worth that.
Step 2 — Check the safety rating and inspection history
FMCSA assigns rated carriers one of three ratings: Satisfactory, Conditional or Unsatisfactory. You want Satisfactory. 'Not Rated' is common for smaller or newer companies and is not automatically a problem, but it means you should weigh the inspection data more heavily.
In the Safety Measurement System you can see vehicle and driver out-of-service percentages from roadside inspections. National averages run roughly 20% for vehicles and 5% for drivers. A carrier meaningfully above those figures is being pulled off the road more often than its peers.
- Operating status: must be ACTIVE
- Safety rating: Satisfactory preferred; investigate Conditional; never book Unsatisfactory
- Vehicle out-of-service rate: compare against the ~20% national average
- Driver out-of-service rate: compare against the ~5% national average
- Crash history: look at the last 24 months, and at whether the carrier was at fault
Step 3 — Verify insurance directly
Federal minimums are $5 million in liability coverage for vehicles seating 16 or more passengers, and $1.5 million for smaller vehicles. FMCSA's Licensing and Insurance system shows whether an active policy is on file.
Ask the operator for a certificate of insurance as well. It should be issued by the insurer or their broker, name the operator exactly as the carrier record does, show current effective dates, and can usually name your organisation as additional insured on request.
Step 4 — Confirm who is actually driving
Brokers are legal and often useful, but you should know whether the company you booked owns the bus. Ask directly: 'Will this trip be operated by your own vehicle and your own employee driver, or subcontracted?' If it is subcontracted, ask for the operating carrier's USDOT number and run the same checks on them.
Also confirm the driver holds a commercial driver's license with a passenger (P) endorsement, and that the company participates in a DOT drug-and-alcohol testing program. Both are legal requirements and both are easy questions for a professional operator to answer.
What we check before an operator joins the network
Every operator in the All Bus Charter network is screened for active USDOT passenger authority, a satisfactory FMCSA safety rating, current commercial liability insurance at or above federal minimums, and a clean recent inspection and crash history. We re-verify authority and insurance on a rolling basis and remove carriers that fall out of compliance.
That screening is a floor, not a substitute for your own five minutes on SAFER. Any operator who hesitates to give you their DOT number has told you something important.
