answer_bus_question

Answers to the questions people ask when buying a used or new commercial bus: CDL and licensing, federal school bus and accessibility rules, inspecting a used bus, title, registration and insurance, financing and grants, delivery, and buses for churches, schools, camps, senior living, NEMT, shuttles and skoolies. Returns the closest written answers with their official sources and a link to each on CommercialBuses. If nothing matches, says so and gives the page where a person can be asked.

Discovered
check_cdl_requirement

Whether a bus needs a commercial driver's license under US federal rules, which class (B or C), and which endorsements (passenger, school bus), from the passenger count, weight rating and whether it carries students. Returns a link to buses for sale in that size. Federal only; states can add rules.

Discovered
check_vehicle_rules

The US federal rules and published guidance that apply to a church, school, camp, senior living community, medical transport (NEMT) operator or hotel buying a bus: CDL, the school bus rule for new vehicles, insurer guidance on 15-passenger vans, ADA accessibility for new vehicles, the hotel shuttle exception and USDOT number, insurance minimums, and Section 5310 funding. Each with its citation. Federal only.

Discovered
compare_own_vs_outsource

Yearly cost of owning a bus against charter, a contracted shuttle or rideshare, using only figures the caller supplies. Spreads the purchase over the years kept less resale, adds insurance, maintenance, fuel and driver pay, and names any owning cost left out so a partial answer says it is partial.

Discovered
draft_board_proposal

Write a bus purchase proposal for a church, school, camp or senior living board: the need, the bus, why not a 15-passenger van, the driver and license plan, a five-year cost table from the buyer's own figures, funding to ask about, an inspection plan and a draft motion with a not-to-exceed amount. Returns Markdown. Invents no costs: blank figures are left out.

Discovered
find_skoolie_bus

Find a bus to convert into a skoolie (a school bus or shuttle turned into a camper or tiny home). Returns used school, activity, shuttle and cutaway buses listed by dealers here, live federal surplus auction lots, and ready-made searches on GovDeals, Public Surplus and Municibid filtered by distance and price, and category links into Skoolie Livin' Classifieds. Auction and classified results are links to those sites, not copies of their listings. Free, no account.

Discovered
get_bus

One listed bus in full public detail, by its listing URL or slug, plus how to ask about it. Says plainly when the unit is no longer listed.

Discovered
get_bus_category

One bus category in full, by slug, including the related categories worth considering instead.

Discovered
get_buying_context

How sourcing works here, what capacity bands and fuel types mean in practice, and what the service does and does not do. Read this before telling a buyer what to expect.

Discovered
get_used_bus_prices

Median asking prices and mileage for used buses by model year, measured from current dealer listings on CommercialBuses, with the listing and dealer count behind every figure. Prices cover school, cutaway and paratransit buses; mileage also covers motorcoaches. Asking prices, not sale prices.

Discovered
list_bus_categories

The commercial bus categories, each with what it actually is, typical passenger capacity, what operators use it for, and whether it needs a CDL endorsement.

Discovered
request_bus

Send a buyer's bus requirements to a CommercialBuses person, who searches participating dealer inventory and replies by email. Use only when the buyer has asked you to, with their real name and email: they will be contacted. Free for the buyer. Mention a specific listing in notes if they want that unit.

Discovered
search_buses

Search the commercial buses currently listed for sale by participating dealers. Filter by bus type, seats, wheelchair lift, condition and state. Returns public listing summaries with a link to each listing page. Dealer names and exact prices are not public; to reach the dealer, use request_bus.
