Bus insurance: the limit follows the seat count

Every rule that reaches a bus starts by counting seats. The federal financial responsibility schedule splits at 16 passengers including the driver; Texas registration attaches at more than 15 and its own table splits again at 26. A charter coach, a school bus under district contract, and a church's 15-passenger van sit on different sides of those lines, which is why they are underwritten as different classes and why the agent you choose should ask about seating before anything else.

The federal schedule: 15 or fewer, 16 or more

The financial responsibility rules for passenger carriers are Subpart B of 49 CFR Part 387. They apply to "for-hire motor carriers transporting passengers in interstate or foreign commerce", and they except a vehicle "transporting only school children and teachers to or from school", a taxicab seating fewer than seven that is not on a regular route, and a commuter vehicle carrying fewer than 16 on a single daily round trip (49 CFR 387.27). Inside the subpart, the schedule has two rows: $5,000,000 for any vehicle with a seating capacity of 16 passengers or more, including the driver, and $1,500,000 for 15 or fewer (49 CFR 387.33, as of 2026). The carrier cannot operate until the coverage is in effect, and the policy stays in force until cancelled on 35 days' written notice (49 CFR 387.31).

Two details in that schedule decide most bus questions. First, the driver's seat counts. A vehicle sold as a "15-passenger van" seats 15 including the driver and lands on the lower row; a 16-seat shuttle lands on the upper one. Second, the row is set by seating capacity, not by how many people rode that day. A 47-seat coach on a half-empty run is still a 47-seat coach. The safety definitions in 49 CFR 390.5 draw the commercial motor vehicle line differently, at more than 8 passengers including the driver for compensation or more than 15 without it, so a nine-seat airport shuttle is a commercial motor vehicle for the safety rules while sitting on the $1,500,000 row for financial responsibility.

The registration that goes with the schedule is the operating authority. The FMCSA's own answer is that companies "Transporting passengers, or arranging for their transport, in interstate commerce" need interstate operating authority in addition to a USDOT number, and that the type of authority requested "dictates the level of insurance/financial responsibilities a company must maintain" (FMCSA, operating authority FAQ). New applicants use the Unified Registration System; the passenger authority is the OP-1(P) type (FMCSA, types of operating authority). A bus operation that never leaves its state registers with the state instead. Texas does it through TxDMV, and our Texas bus insurance page walks that statute and rule.

Charter bus insurance: the for-hire class

A charter or tour operator is the passenger carrier the federal rule was written for: for hire, often crossing state lines, usually in coaches of 16 seats or well beyond. If any trip is interstate, the $5,000,000 row applies to every vehicle of that size, the operating authority applies to the company, and the policy on file with the FMCSA is the one the certificate endorsement attaches to. If every trip is intrastate, the state's registration and its table govern, and in Texas the state's own published table places a vehicle of 26 or more passengers at the same $5,000,000 figure while placing the smaller bus lower (see the Texas page for the exact wording of TxDMV's counting convention).

Beyond auto liability, a charter operation carries physical damage on the coaches, which a lender will require regardless; general liability for the terminal, the ticket counter, and passengers on foot; and workers compensation for drivers and mechanics in nearly every state. Two questions belong on the list rather than assumptions: whether the auto policy responds to a passenger injured while boarding or in the luggage bay, and whether the contracts you sign with schools, tour packagers, or sports programs name an additional insured or a limit above the regulatory floor. The contract limit is frequently the binding one.

School bus insurance: a contract-driven segment

The federal passenger schedule excepts a vehicle transporting only school children and teachers to or from school, so a school bus contractor's limit is not set by 49 CFR 387.33. It is set by the district. Texas is the worked example here: Education Code Section 34.002 has the Department of Public Safety, with the Texas Education Agency's advice, "establish safety standards for school buses used to transport students", and Section 34.008 lets a school board contract with "a commercial transportation company" on the condition that the contractor's drivers are DPS-certified and that buses used for 15 or more students meet or exceed those standards (Texas Education Code Chapter 34). Neither section names an insurance coverage or amount. The contract does.

The state registration layer still applies. In Texas, operating "a commercial school bus" is a registration trigger in its own right with TxDMV, and the agency's published table carries a specific row for a for-hire school bus running a residence-to-school route inside a municipality, quoted on the Texas page. The DPS standards themselves and the district contracts sit outside this page, which does not guess at a district's limit. An agent quoting a school bus contractor should ask for the transportation contract first; the coverage schedule inside it is the requirement.

Church van insurance: the 15-passenger van, underwritten as its own class

A congregation's van is usually a 15-passenger unit, it is rarely for hire, and it is driven by volunteers. Those three facts place it outside the federal for-hire schedule and, in many states, outside commercial registration. Texas exempts from Chapter 643 "a motor vehicle used to transport passengers operated by an entity whose primary function is not the transportation of passengers, such as a vehicle operated by a hotel, day-care center, public or private school, nursing home, or similar organization" (Texas Transportation Code Section 643.002). A church is not named in that list. The van reads like a "similar organization" case, and the way to settle it is to ask TxDMV, not to assume.

What makes the class its own is the vehicle. NHTSA's page on 15-passenger vans calls them "cumbersome vehicles" that "can pose a safety risk to inexperienced van drivers", and its recommendations are the underwriting questions in different words: seat belts on every occupant, drivers who are "trained and experienced", tires checked "at least once a week", and "no loads are placed on the roof". The agency's safety fact is that 57 percent of the 235 occupants of 15-passenger vans killed in rollover crashes from 2010 to 2019 were ejected, and that an unrestrained occupant in a single-vehicle crash is "approximately four times more likely to be killed than a restrained occupant" (NHTSA, 15-Passenger Vans). NHTSA also notes that electronic stability control has removed the rollover concern for newer vans, which is why the model year is one of the first things an agent asks.

Expect the agent to want the driver roster and how it is screened, whether anyone under 25 drives, a tire and inspection program, and how many seats are filled on a typical trip. A church's van is a commercial auto exposure whatever its registration status, and a personal auto policy is not the place for it. Many congregations place the van on the same package as the building and the general liability, which is a question for the agent who writes that package.

What an agent who writes buses will ask

Seating capacity of every unit, including the driver, because it decides the row. Whether any trip crosses a state line, and whether you hold or are applying for FMCSA authority. The mix of work: charter, tour, school, shuttle, congregation. Copies of the contracts you run under, because a district or a tour packager frequently sets a limit above the regulatory one. Driver records, ages, and CDL passenger endorsements. Vehicle ages, values, and lienholders. An agent who asks for the seat count and the contracts before quoting has written this class; one who quotes from the vehicle count alone has not.

This site publishes no premium figures. Rates vary by carrier, state, seating capacity, radius, driver records, contract limits, and loss history.

Frequently Asked Questions

What is the federal minimum liability limit for a bus?
For a for-hire carrier of passengers in interstate or foreign commerce, 49 CFR 387.33 sets $5,000,000 for a vehicle with a seating capacity of 16 or more passengers including the driver and $1,500,000 for 15 or fewer, as of 2026. The carrier must have that coverage in effect before operating, and cancellation takes 35 days’ written notice (49 CFR 387.31). A bus that never crosses a state line for hire is outside that subpart and answers to its state instead.
Does a charter bus company need FMCSA operating authority?
If it transports passengers for compensation across state lines, yes. The FMCSA’s own answer is that companies transporting passengers, or arranging their transport, in interstate commerce need interstate operating authority in addition to a USDOT number, and the type of authority requested sets the insurance the FMCSA requires. New applicants register through the Unified Registration System; the passenger authority is the OP-1(P) type. An intrastate charter operator registers with its state agency instead, which in Texas is TxDMV.
Who sets the insurance requirement for a school bus contractor?
Mostly the district. In Texas, Education Code Section 34.008 lets a school board contract with a commercial transportation company on the condition that its drivers are DPS-certified and its buses meet the DPS safety standards under Section 34.002; neither section names an insurance amount. The number you must show is in the district’s contract, and TxDMV separately requires a commercial school bus to register and carry its published minimum. Read the contract before the vehicle list.
Is a church van a commercial vehicle?
Under the federal safety definitions, a vehicle designed or used to transport more than 15 passengers including the driver is a commercial motor vehicle even when nobody pays for the ride (49 CFR 390.5). For state registration, Texas exempts a passenger vehicle operated by an entity whose primary function is not passenger transport, listing schools, hotels, day-care centers, and nursing homes and “similar organization” (Transportation Code Section 643.002). A congregation’s van reads like that exemption, but the statute does not name churches, so confirm with TxDMV. Either way, the van is underwritten as a commercial auto, not on a personal policy.
What moves a bus insurance premium?
Seating capacity, because it decides which limit applies at every level; radius and whether any trips cross a state line; the number of units and their age and value; driver records, ages, and whether they hold a CDL with a passenger endorsement; the share of school, charter, or tour work; and loss history. Rates vary by carrier and by all of those inputs, so this site publishes no premium figures.
