12.1 Business Auto Coverage Form and Covered Auto Symbols

Key Takeaways

  • The BACF (CA 00 01) has five sections: Covered Autos, Liability, Physical Damage, Conditions, and Definitions.
  • Symbol 1 = any auto (broadest); Symbol 7 = specifically described autos; Symbol 8 = hired; Symbol 9 = non-owned.
  • Symbols 1 and 2 cover newly acquired autos automatically; Symbol 7 requires reporting within 30 days for non-replacement acquisitions.
  • Trailers of 2,000 lbs or less designed for private passenger autos get automatic liability coverage.

The Business Auto Coverage Form (BACF)

The Business Auto Coverage Form (ISO form CA 00 01) is the workhorse of commercial automobile insurance. Together with the Commercial Auto Declarations (CA DS 03) and the Common Policy Conditions (IL 00 17) and Common Policy Declarations (IL 00 21), it forms a complete monoline auto policy. On the national exam, expect the current edition to be cited generically; ISO has issued the CA 00 01 11 20 edition, but candidates are tested on concepts, not edition footers.

The BACF is divided into five numbered sections that you must be able to identify on sight:

The Five Sections of the BACF

SectionTitleWhat it does
ICovered AutosDefines, via symbols, which autos are covered for each coverage
IICovered Autos Liability CoverageBodily injury/property damage liability + supplementary payments
IIIPhysical Damage CoverageComprehensive, specified causes of loss, collision, towing
IVBusiness Auto ConditionsLoss conditions and general conditions
VDefinitionsDefines auto, accident, insured, loss, etc.

Trap: Many candidates confuse Section I (which autos) with Section II (liability). Section I assigns nothing but symbols; the dollar coverage lives in Sections II and III.

Covered Auto Symbols

The heart of the BACF is the numbered symbol system. A symbol is entered next to each coverage on the Declarations to define which vehicles that coverage applies to. The exam loves symbol-recognition questions, so memorize the table below cold:

The Standard Covered Auto Symbols

SymbolDescription
1Any auto (broadest; required for true any-auto liability)
2Owned autos only
3Owned private passenger autos only
4Owned autos other than private passenger
5Owned autos subject to no-fault laws
6Owned autos subject to compulsory uninsured motorists law
7Specifically described autos (those listed on the Declarations)
8Hired autos only (leased, rented, borrowed — not owned)
9Non-owned autos only (e.g., employees' personal cars used in business)
19Mobile equipment subject to compulsory financial responsibility

Trap: Symbol 8 (hired) excludes autos you own. Symbol 9 (non-owned) excludes both owned and hired. To cover an employee borrowing a friend's truck on company business, you need Symbol 9.

Newly Acquired and Trailer Coverage Triggers

The symbol you choose drives automatic coverage for newly acquired autos:

  • Symbol 1 (any auto) and Symbol 2 (owned) automatically cover newly acquired autos with no reporting requirement.
  • Symbol 7 (specifically described) covers a newly acquired auto only if (a) it replaces a described auto, or (b) the insurer covers all your autos, AND you tell the insurer within 30 days of acquisition.

Trailers with a load capacity of 2,000 lbs or less designed for use with a private passenger auto receive automatic liability coverage. Mobile equipment carried or towed by a covered auto is also covered for liability.

Why Symbols Matter More Than Any Other Auto Concept

Covered-auto symbols are numbers entered next to each coverage in the Business Auto declarations that define which autos that coverage applies to. The same policy can carry different symbols for liability versus physical damage — for example, Symbol 1 (any auto) for liability but Symbol 7 (specifically described autos) for collision, so the insured has the broadest possible liability protection while paying physical-damage premium only on listed vehicles.

1Any auto (broadest liability)

3Owned private passenger autos only
4Owned autos other than private passenger
5Owned autos subject to no-fault

9Non-owned autos only (employees' autos used in business)
19Mobile equipment subject to compulsory/financial-responsibility laws

Newly Acquired and Hired/Non-Owned Triggers

Under broad symbols (1, 2), newly acquired autos are covered automatically. Under Symbol 7, a newly acquired auto is covered for 30 days only if the insurer already covers all owned autos or the insured reports it within 30 days. Symbols 8 and 9 are how a business picks up hired and employee-owned non-owned auto exposure without scheduling each vehicle, a frequent gap for businesses whose staff run errands in personal cars.

Why Symbols Are the Whole Game

Commercial-auto questions almost always reduce to reading the covered-auto symbols, so internalize what each one captures and how they combine. Symbol 1 gives the broadest liability because it reaches any auto the insured uses, owned or not, which is why it is the standard choice for liability even when physical damage is restricted to Symbol 7 specifically described autos to control premium. Symbols 8 and 9 are the workhorses for businesses whose exposure comes from rented vehicles and from employees running errands in their own cars, two gaps that surprise small employers.

Because the same policy can pair a broad liability symbol with a narrow physical-damage symbol, a stem that lists different symbols for different coverages is testing whether you understand that coverage applies only to the autos a given symbol describes. Translating the symbol numbers into the set of vehicles they cover is the single most reliable way to answer these items.
