The Business Auto Policy (BAP) is the standard ISO commercial auto form — referenced as ISO CA 00 01 (the current version is the 2013 edition). It's used for most businesses with 1–25 owned vehicles + drivers. The key thing to understand: coverage depends entirely on the 9 'symbols' listed on the declarations page. Symbol 1 (Any Auto) is broadest; Symbol 7 (Owned Autos Only) is most restrictive. Wrong symbol selection = silent coverage gap. Other commercial auto forms exist for specific industries: Garage Coverage Form (CA 00 05) for auto dealers + service stations, Truckers Coverage Form (CA 00 12) for for-hire trucking, and Motor Carrier Coverage Form (CA 00 20) for interstate motor carriers. Most other commercial businesses use BAP. Typical small-business BAP: $1,200–$4,500/year per vehicle depending on type + use + driver MVR.
The Business Auto Policy is the workhorse of commercial-auto insurance — but its protection isn't determined by the policy document alone. It's determined by which of the 9 symbols are listed next to each coverage on your declarations page. Most businesses never read past the premium amount + carrier name, and most coverage gaps come from symbol-selection mistakes.

What is the Business Auto Policy (BAP)?
The Business Auto Policy (BAP) is the standard commercial-auto insurance form developed by ISO (Insurance Services Office) + adopted by most major commercial auto carriers. The current edition is ISO CA 00 01 (10 13) — the 2013 revision is the current industry standard.
- Who uses BAP: most non-trucking commercial businesses with 1-25 vehicles (contractors, service businesses, retail delivery, sales fleets, professional services with company vehicles).
- Who doesn't use BAP: auto dealers + service stations (use Garage Coverage Form CA 00 05); for-hire trucking (Truckers Coverage Form CA 00 12); interstate motor carriers (Motor Carrier Coverage Form CA 00 20); large-fleet operators (often custom-written forms).
- What it covers (potentially): Liability for BI + PD, Medical Payments, Uninsured/Underinsured Motorists, Physical Damage (Collision + Comprehensive), Towing + Labor.
- What determines scope: the SYMBOLS listed next to each coverage on the declarations page. The same BAP form can be narrow (Symbol 7 only, owned autos) or broad (Symbol 1, any auto) depending on the symbols selected.
- Standard limits: $1M CSL (Combined Single Limit) is the most-common; $500K minimum + $5M+ available with excess/umbrella.
- Standard exclusions: war, nuclear hazard, intentional acts, racing, livery (passenger-for-hire), workers comp claims (those go through WC).
The 9 symbols decoded
Each coverage on the BAP declarations page has one or more symbols next to it. Each symbol means a different set of vehicles is covered for that coverage:
| Symbol | Description | What it covers |
|---|---|---|
| 1 | Any "Auto" | BROADEST — any vehicle, owned or not. Usually used for Liability only; rarely available for Physical Damage. |
| 2 | Owned "Autos" Only | Any vehicle the named insured OWNS — includes newly-acquired autos automatically. Common default for Liability. |
| 3 | Owned Private Passenger "Autos" Only | Owned passenger cars only (NOT trucks, vans, trailers). Rarely used standalone. |
| 4 | Owned "Autos" Other Than Private Passenger "Autos" Only | Owned trucks + vans + commercial vehicles only (NOT passenger cars). Used for commercial-fleet-only operations. |
| 5 | Owned "Autos" Subject to No-Fault | Owned autos in no-fault states only — used for Personal Injury Protection. |
| 6 | Owned "Autos" Subject to Compulsory Uninsured Motorists Law | Owned autos in states with compulsory UM coverage — used for UM coverage. |
| 7 | Specifically Described "Autos" | NARROWEST — only the autos specifically listed on the declarations page schedule. New autos NOT auto-covered. Common for Physical Damage to limit premium. |
| 8 | Hired "Autos" Only | Autos the business rents, leases, hires, or borrows. Critical for HNOA coverage. |
| 9 | Non-Owned "Autos" Only | Autos owned by employees or others when used in business operations. The other half of HNOA. |
Combinations: most BAPs list multiple symbols per coverage. E.g., Liability with "1" = any auto; Physical Damage with "7" = only scheduled vehicles. HNOA = Symbols "8, 9" together.
5 coverages in a BAP + when symbols matter
| Coverage | What it does | Typical symbols |
|---|---|---|
| Liability | Pays third parties for BI + PD caused by the insured's covered auto | 1 (Any Auto) — broadest. 2 (Owned Only) — common default. |
| Medical Payments | Pays medical expenses for occupants of covered autos regardless of fault | 2 (Owned) or 7 (Scheduled) |
| Uninsured / Underinsured Motorists | Pays YOUR injured occupants when the at-fault other driver lacks adequate insurance | 2 (Owned) typically; 6 in states with compulsory UM |
| Physical Damage — Collision | Pays for damage to covered autos from collision (rollovers, accidents) | 7 (Scheduled) — narrowest, requires explicit listing of each vehicle on the schedule |
| Physical Damage — Comprehensive (Other Than Collision) | Pays for damage from theft, vandalism, fire, weather, animal collision | 7 (Scheduled) |
| Towing & Labor | Pays for disabled-vehicle towing + roadside labor | 7 (Scheduled) |
| HNOA (Hired + Non-Owned) | Covers vehicles rented or borrowed for business + employees' personal vehicles used for work | 8 (Hired) + 9 (Non-Owned). Critical add-on. |
Common symbol-selection errors
Most BAP coverage gaps come from symbol-selection mistakes at policy inception. Five most-common errors:
- 1. Symbol 7 Liability instead of Symbol 1 or 2 — narrowest liability scope means newly acquired vehicles aren't covered. If you buy a new truck mid-term + have an accident on day 3, claim denied because the vehicle isn't on the schedule.
- 2. Forgetting Symbols 8 + 9 (HNOA) — Symbol 7 Liability won't cover a rental car you drove to a client meeting or an employee's personal car used for business errands. Lack of HNOA is the single most-common commercial auto coverage gap.
- 3. Wrong Symbol for Medical Payments — Med Pay typically follows the owned-autos symbol (2 or 7). If symbol 7 Med Pay + a passenger in a rental car (Symbol 8 territory), the rental occupant has no Med Pay coverage.
- 4. Symbol 1 (Any Auto) when underwriting requires Symbol 7 — some underwriters insist on Symbol 7 to control exposure. If you have Symbol 1 written but underwriting attached "Symbol 7 only" amendment, the amendment overrides — you have narrower coverage than the declarations indicate.
- 5. Missing Symbol 5 / 6 in no-fault / compulsory UM states — Symbol 5 + 6 are state-specific. Missing them in the wrong state means state-mandated coverage isn't fulfilled, exposing the business to direct state-DOI action.

BAP vs other commercial auto forms
| Form | ISO Code | Used for |
|---|---|---|
| Business Auto Policy | CA 00 01 | Most non-trucking commercial businesses with 1-25 vehicles. Default form. |
| Garage Coverage Form | CA 00 05 | Auto dealers, service stations, auto repair shops, body shops. Covers shop operations + dealer-plate-driving + customer cars in care/custody. |
| Truckers Coverage Form | CA 00 12 | For-hire trucking — operators hauling third-party cargo under their own MC Authority. Includes Motor Truck Cargo + FMCSA filings. |
| Motor Carrier Coverage Form | CA 00 20 | Interstate motor carriers — broader than Truckers Form; covers private + for-hire trucking + complex multi-state operations. |
| Public Auto Coverage | CA 99 09 | Taxis, limousines, ride-share, paratransit. Higher-severity passenger-for-hire class. |
| Auto Dealers Coverage Form | CA 00 25 | Newer replacement for Garage Coverage Form on some markets. Specifically designed for new + used auto dealers. |
Most small businesses use BAP. Industry-specific forms exist when the operations have specialized exposures (dealer customer cars, for-hire cargo, paratransit) that BAP doesn't cover well. See Commercial Auto pillar for the broader commercial auto landscape; Commercial Truck Insurance for the trucking-specific path.
How to read your BAP declarations page
The declarations page (or "dec page" / "decs") is the personalized front page of your policy. Five things to verify at every renewal:
- 1. Symbol numbers next to each coverage — confirm Liability has Symbol 1 (or 2 minimum); HNOA has Symbols 8 + 9; Physical Damage has Symbol 7 with all your vehicles listed in the schedule.
- 2. Vehicle schedule completeness — every vehicle you own + drive for business should be listed with VIN, year, make, model, garage state. Missing vehicles = no coverage (for Symbol 7) or under-rated premium (for Symbol 2 owned).
- 3. Limit amounts — Liability CSL ($500K minimum, $1M industry-standard, $2M-$5M for larger operations). Physical Damage = stated value or ACV per vehicle.
- 4. Deductibles — Collision deductible ($500-$2,500 typical); Comprehensive deductible ($500-$2,500 typical). Higher deductible = lower premium.
- 5. Driver schedule — many BAPs list named drivers + their MVR rating. Excluded drivers (DUIs, major violations) cannot operate covered vehicles without voiding coverage.
- 6. Premium reconciliation — verify the premium charged matches the carrier's quote. Audit endorsement + retrospective rating may apply to large policies.
Frequently Asked Questions
What's the difference between a Business Auto Policy and Commercial Auto insurance?
They're closely related but not identical. 'Commercial Auto Insurance' is the GENERAL TERM for insurance covering vehicles used in business operations. 'Business Auto Policy (BAP)' is the specific ISO form (CA 00 01) used to write most commercial auto insurance. Most businesses with 1-25 vehicles use a BAP — so the terms are often used interchangeably. The distinction matters when you have specialty operations: auto dealers use Garage Coverage Form (CA 00 05) NOT BAP; for-hire truckers use Truckers Coverage Form (CA 00 12) NOT BAP; interstate motor carriers use Motor Carrier Coverage Form (CA 00 20). See our Commercial Auto pillar for the broader landscape.
What are the 9 symbols on a BAP and why do they matter?
The 9 symbols on the BAP declarations page determine WHICH VEHICLES are covered for each coverage type. Symbol 1 (Any Auto) is broadest — any vehicle. Symbol 2 (Owned Autos Only) covers vehicles your business owns. Symbol 7 (Specifically Described Autos) is narrowest — only autos on the schedule. Symbols 8 + 9 are HNOA (Hired + Non-Owned). The same BAP policy can have very different coverage scope depending on which symbols are selected. Wrong symbol = silent coverage gap that's only discovered at claim time. ALWAYS verify your declarations page symbols match your actual operations.
How much does a Business Auto Policy cost?
Typical small-business BAP: $1,200-$4,500/year per vehicle depending on: vehicle type (sedans cheaper than commercial trucks), use (delivery + sales routes cost more than executive-driven), driver MVR (clean MVR = best rate; major violations = 50-100% surcharge), business class (some classes face higher rates), state (CA + NY + NJ + FL = highest premiums for same risk), limits ($500K minimum to $5M+ available), deductible (higher deductible = lower premium). Multi-vehicle fleets get fleet discounts (typically 10-25% off per-vehicle rates).
What is HNOA and why is it always missing?
HNOA = Hired and Non-Owned Auto. It's Symbols 8 + 9 on the BAP declarations page. Hired (Symbol 8) covers rented + leased + borrowed vehicles for business. Non-Owned (Symbol 9) covers vehicles owned by employees but used in business operations. HNOA is the most-missed BAP add-on because: (1) businesses think their company-vehicle BAP automatically covers rentals — it doesn't (Symbol 7 doesn't include rentals); (2) businesses think employees' personal auto covers them at work — personal auto excludes commercial use entirely. Without HNOA, a rental-car accident or employee's personal-car business-use accident has NO coverage. Add HNOA to every BAP — cost is typically $50-$300/year, the cheapest critical coverage you'll buy.
What's on a BAP declarations page that I should verify?
Six items to verify at every renewal: (1) Named Insured exact legal name — entity-name mismatch = coverage denial at claim time. (2) Symbol numbers next to each coverage — Liability Symbol 1 or 2 (not 7); HNOA Symbols 8 + 9 present. (3) Vehicle schedule complete — every business vehicle listed by VIN + year + make + model + garage state. (4) Limit amounts — Liability CSL at least $1M for most operations; Physical Damage stated value per vehicle. (5) Deductibles — Collision + Comp typically $500-$2,500. (6) Driver schedule — named + excluded drivers per state requirements. Spend 10 minutes on the declarations page at every renewal. It saves claims-time surprise.
When should I NOT use a Business Auto Policy?
Five scenarios where you should NOT use BAP: (1) Auto dealers + repair shops + service stations — use Garage Coverage Form (CA 00 05) which covers customer-car care/custody + dealer-plate-driving + shop operations. (2) For-hire trucking under your own MC Authority — use Truckers Coverage Form (CA 00 12) which includes Motor Truck Cargo + FMCSA filings. (3) Interstate motor carriers — use Motor Carrier Coverage Form (CA 00 20). (4) Taxis + limousines + ride-share + paratransit — use Public Auto Coverage (CA 99 09). (5) Large fleets ($10M+ premium) — often use custom-written manuscript policies or self-insured-retention structures instead of standard BAP. For most other commercial businesses, BAP is the right form.
Can I use my personal auto insurance for business driving?
No — personal auto policies EXPLICITLY EXCLUDE commercial use in 49 of 50 states. Common exclusions: livery (passenger-for-hire), delivery, hauling for hire, business use beyond commuting, regularly transporting goods for business. If you drive your personal car for client meetings, deliveries, employee errands, or anything beyond commuting + occasional personal errands, you need either: (a) HNOA endorsement on a BAP if your business owns other vehicles + uses your personal car occasionally; (b) Standalone Commercial Auto policy covering your personal car for business use; (c) Hybrid policy (some carriers) that endorses personal auto for business use — rare + often expensive.
What happens if I have an accident with the wrong BAP symbol?
Coverage denied or under-covered. Three common scenarios: (1) Symbol 7 Liability + new vehicle: bought a new truck mid-policy + had accident on day 3; vehicle wasn't yet on the schedule → claim denied for that vehicle. (2) No HNOA + rental car accident: drove a Hertz rental to a client meeting + had accident → BAP Symbol 7 doesn't cover rentals; personal auto excludes commercial; you're personally liable. (3) Symbol 1 Liability written but underwriting attached 'Symbol 7 only' amendment: amendment overrides declarations — narrower coverage than the dec page indicates. ALWAYS read the policy + any attached amendments at every renewal — the declarations alone don't tell the full story.
How is BAP different from a personal auto policy?
Four key differences: (1) Coverage scope — BAP covers business-use exposures (commercial activities, delivery, sales routes, employee driving); personal auto excludes commercial use entirely. (2) Symbols system — BAP uses 9 symbols to define coverage scope; personal auto applies to listed vehicles + family drivers. (3) Higher limits typical — BAP usually $1M+ CSL; personal auto typically $100K-$500K. (4) Different underwriting — BAP underwriting looks at business operations, driver MVR pool, fleet size, garaging locations; personal auto looks at named insureds + occasional family drivers. The two policies do not substitute — businesses need commercial auto for commercial driving.
Do I need a BAP if I only have one company car?
Yes if the car is owned by your business OR used regularly for business operations. The personal-auto exclusion applies even to a single vehicle — if you regularly drive to client sites, deliveries, employee errands, etc., personal auto WILL deny the claim. A single-vehicle BAP starts around $1,200-$2,500/year for a typical small-business sedan or van with clean MVR. If your business is brand-new + revenue is low, you can sometimes get coverage on a Business Owners Policy (BOP) with a commercial-auto endorsement — but most BOPs cap coverage at 1-2 vehicles + limit usage. Talk to a commercial-insurance broker before assuming personal auto covers any business driving.
