12.1 Business Auto Coverage Form and Covered Auto Symbols

Key Takeaways

  • The Business Auto Coverage Form (ISO CA 00 01) insures commercial vehicles using covered-auto designation symbols 1-9 entered on the declarations next to each coverage.
  • Symbol 1 (Any Auto) is broadest, reaching owned, hired, AND non-owned autos; Symbol 7 (Specifically Described Autos) is narrowest, covering only scheduled vehicles.
  • WHO IS AN INSURED is broad: named insured for any covered auto, permissive users of owned/hired/borrowed autos, and anyone vicariously liable for an insured's conduct.
  • Newly acquired autos are automatically covered for 30 days under Symbols 1, 2, 3, or 4; Symbol 7 requires notice within 30 days to cover an added vehicle.
  • Employees driving their OWN autos on business are not liability insureds; the employer relies on Symbol 9 (non-owned) for its vicarious exposure only.

What the Business Auto Coverage Form Is

The Business Auto Coverage Form (BACF), ISO form CA 00 01, is the standard policy for insuring cars, trucks, trailers, and vans owned, hired, or used by a business. It replaced the older Business Auto Policy terminology and is the commercial cousin of the Personal Auto Policy (PAP). A business may own zero vehicles or five hundred, plus rent and borrow others, so the form never lists every auto by VIN. Instead it describes categories of autos with covered-auto designation symbols.

The practical advantage is flexibility: as a fleet grows or shrinks during the policy term, the symbols keep describing the right categories of vehicles without an endorsement for every change. This is why commercial auto is frequently auditable, with the final premium adjusted at expiration.

One BACF can simultaneously provide third-party liability, physical damage to owned autos, auto medical payments, and uninsured/underinsured motorist (UM/UIM) coverage. Each coverage is activated only when a symbol and a limit appear on the declarations. Because the symbols are chosen line by line, an insurer can offer broad liability (Symbol 1) while restricting expensive physical damage to scheduled units (Symbol 7).

How the Form Is Built

The BACF is modular. A coverage exists only when both a symbol and a limit are shown.

SectionFunction
Item One - DeclarationsNamed insured, policy period, limits, and the symbols selected per coverage
Section I - Covered AutosDefines symbols 1-9 and the 30-day newly-acquired-auto rule
Section II - Covered Autos LiabilityThird-party bodily injury and property damage, plus supplementary payments
Section III - Physical DamageComprehensive, collision, specified causes of loss, towing
Section IV - ConditionsDuties after loss, two-or-more-forms, transfer of rights (subrogation)
Section V - DefinitionsAccident, auto, bodily injury, property damage, loss, mobile equipment

Covered-Auto Designation Symbols (1-9)

Because each coverage line carries its own symbol, liability is commonly written far broader than physical damage.

SymbolCategoryPlain Meaning
1Any AutoOwned, hired, AND non-owned (broadest)
2Owned Autos OnlyEvery auto the insured owns, any type
3Owned Private Passenger OnlyOwned cars/SUVs, not trucks
4Owned, Other Than Private PassengerOwned trucks, vans, specialty units
5Owned Autos Subject to No-FaultOwned autos in PIP/no-fault states
6Owned Autos Subject to Compulsory UMOwned autos where UM is mandatory
7Specifically Described AutosONLY vehicles listed on the schedule
8Hired Autos OnlyRented, leased, or borrowed (not owned)
9Non-Owned Autos OnlyEmployee/partner personal autos used for business

Exam trap: Symbol 1 is the only symbol that automatically reaches hired and non-owned exposure. A risk written Symbol 2 has a gap for rentals (needs 8) and for employee cars (needs 9). Physical damage is usually written Symbol 7 because an insurer will only pay to repair vehicles it knows about.

Newly Acquired Autos and Trailers

When a business buys a vehicle mid-term, whether it is covered before the insured calls the agent depends on which symbol applies. This is one of the most reliably tested points on the BACF.

  • Symbols 1, 2, 3, 4: a newly acquired auto is automatically covered for 30 days with no notice required, because these symbols already describe broad categories of owned autos.
  • Symbol 7 (Specifically Described): a newly acquired auto is covered only if the insured asks the insurer to add it within 30 days of acquisition, OR if it replaces a scheduled auto.
  • Trailers with a load capacity of 2,000 pounds or less are automatically covered for liability without being scheduled.

The logic is that broad symbols already contemplate the category, so the insurer accepts the new unit; a scheduled-auto policy (Symbol 7) underwrites each vehicle individually, so it needs to be told.

Who Is an Insured

The insured definition is intentionally broad and layered:

  • The named insured - for ANY covered auto.
  • Permissive users - anyone using a covered auto the named insured owns, hires, or borrows WITH permission.
  • Anyone legally responsible for the conduct of an insured, but only to the extent of that liability (e.g., an employer liable for an employee's covered driving).

Key carve-out: the owner of a hired or borrowed auto is NOT an insured (a rental company is not an insured under your BACF), and an employee is not an insured for liability while driving the employee's OWN auto. For employee-owned cars the employer relies on Symbol 9, which protects the employer's vicarious liability only - the employee's personal auto policy is primary.

The Key Symbols to Memorize

SymbolCovered autos
1Any auto (broadest — owned, hired, non-owned)
2Owned autos only
7Specifically described autos (those on the schedule)
8Hired autos only
9Non-owned autos only

For liability, Symbol 1 (Any Auto) is broadest. For physical damage, you cannot use Symbol 1; coverage is limited to owned (2) or scheduled (7) autos because you only pay to repair autos you own/control. Symbols 8 and 9 add hired and employee-owned exposure — the combination 7-8-9 is common for a business with scheduled autos plus rentals and employee driving.

Why Symbol Choice Drives Coverage

Choosing Symbol 1 for liability automatically picks up newly acquired autos with no reporting requirement; choosing Symbol 7 means a new auto must be reported within 30 days for liability to attach. The symbol on each coverage line, not the policy generally, decides which autos are covered — a heavily tested concept.
