12.1 Business Auto Coverage Form and Covered Auto Symbols

Key Takeaways

  • The Business Auto Coverage Form (ISO CA 00 01) insures non-dealer, non-motor-carrier businesses and has five sections: Covered Autos, Liability, Physical Damage, Conditions, and Definitions.
  • Covered auto symbols 1–19 entered next to each coverage on the declarations define which autos that coverage applies to.
  • Symbol 1 (Any Auto) is broadest but applies to liability only; physical damage must use Symbol 7 (Specifically Described Autos).
  • Symbols 2–6 and 19 cover newly acquired autos automatically; Symbol 7 requires reporting a new auto within 30 days.

The Business Auto Coverage Form

The Business Auto Coverage Form (BACF), ISO form CA 00 01, is the workhorse of commercial auto insurance. It insures cars, vans, trucks, and trailers owned, hired, or used by a business that is not a motor carrier for hire and is not an auto dealer. A complete Business Auto Policy (BAP) is assembled from four pieces: the common policy Declarations, the BACF, the Common Policy Conditions (IL 00 17), and any endorsements.

The BACF is organized into five sections you must memorize for the exam:

SectionTitleWhat it does
ICovered AutosAssigns symbols 1–19 by line
IICovered Autos LiabilityThird-party BI/PD coverage
IIIPhysical DamageFirst-party damage to your auto
IVBusiness Auto ConditionsLoss and general conditions
VDefinitionsDefines auto, insured, loss

The form is monoline — it covers only autos. To add property, GL, or crime, the insurer issues a Commercial Package Policy (CPP) wrapping multiple coverage parts under one declarations page.

How Covered Auto Symbols Work

A fleet is constantly changing — vehicles are bought, sold, and rented. Rather than scheduling each unit, the underwriter assigns a covered auto symbol (1–19) to each coverage on the declarations. The symbol entered next to a coverage defines which autos that coverage applies to. The same vehicle can carry different symbols for different coverages; for example, Symbol 1 for liability but Symbol 7 for physical damage.

The core symbols

  • Symbol 1 — Any Auto: Broadest. Covers all autos, owned or not. Used only for liability.
  • Symbol 2 — Owned Autos Only: All autos you own, plus those acquired later.
  • Symbol 3 — Owned Private Passenger Autos Only.
  • Symbol 4 — Owned Autos Other Than Private Passenger.
  • Symbol 5 — Owned Autos Subject to No-Fault (PIP states).
  • Symbol 6 — Owned Autos Subject to Compulsory UM.
  • Symbol 7 — Specifically Described Autos: Only autos listed on the schedule. The narrowest — required for physical damage.
  • Symbol 8 — Hired Autos Only (leased, rented, borrowed, but not owned).
  • Symbol 9 — Nonowned Autos Only (employee-owned autos used in business).

Automatic Acquisition and the Symbol 7 Trap

A frequent exam trap turns on automatically acquired autos. Under Symbols 2, 3, 4, 5, 6, and 19, newly acquired autos are covered automatically for the rest of the policy period. Under Symbol 7 (Specifically Described Autos), a newly acquired auto is covered only if the insurer already insures all your autos or the auto replaces a scheduled one, and you report it within 30 days of acquisition.

Exam trap: Symbol 1 sounds like it covers everything, but it applies only to liability. You cannot buy physical damage on Symbol 1 because the insurer will not pay collision/comprehensive on a borrowed or any unknown auto. Physical damage must be written on Symbol 7 (scheduled) so the insurer knows the values at risk.

Newly acquired — worked example

A contractor with Symbol 2 liability buys a new pickup on June 1. Coverage attaches the moment of acquisition with no reporting requirement. Compare a contractor with Symbol 7 physical damage: the new pickup is covered only if the insurer writes physical damage on all owned autos and the truck is reported within 30 days; otherwise there is no comprehensive or collision.

The Higher Symbols and Combining Designations

Symbols above 9 round out the schedule and appear on exams less often but are still testable. Symbol 10 is reserved for a custom designation written into the form. The dealer-specific symbols are 21–31 and belong on the Garage form, not the BACF. For the BACF, the workhorse combinations are predictable:

  • Liability: Symbol 1 (Any Auto) for the broadest protection, or Symbols 2/8/9 combined when an insured wants owned + hired + nonowned but not the absolute breadth of Symbol 1.
  • Physical Damage: Symbol 7 (scheduled autos), often paired with 8 to pick up hired-auto physical damage and 9 is not used for physical damage because nonowned autos belong to others.
  • Medical Payments / No-Fault / UM: Symbols 2–6 depending on state mandates.

Hired and nonowned distinction

The exam repeatedly separates hired (Symbol 8 — autos you lease, rent, or borrow, including from employees if you pay) from nonowned (Symbol 9 — autos owned by employees or others used in your business but not hired by you). A pizza shop whose drivers use their own cars needs Symbol 9 liability so the shop is protected when an employee causes an accident on the job. A firm that rents trucks for a move needs Symbol 8. Misclassifying these is a classic distractor.

Mobile Equipment vs. Auto and the Coverage Boundary

The BACF defines "auto" to exclude mobile equipment (bulldozers, forklifts, cranes not licensed for road use), which is instead covered under the CGL as part of operations. But equipment that is subject to motor-vehicle registration, or that carries permanently mounted equipment and travels the public roads, can be an auto. This auto-vs-mobile-equipment line decides which policy responds.

PropertyTypically covered under
Licensed truck/vanBusiness Auto Policy
Bulldozer, forklift on siteCGL (mobile equipment)
Self-propelled equipment on public roadsAuto

Trap: When a cherry-picker rigged on a registered truck causes a loss, the truck is an auto (BAP) but the operation of the mounted device may engage the CGL - the exam tests this boundary with construction-equipment fact patterns.
