12.1 Business Auto Coverage Form and Covered Auto Symbols

Key Takeaways

  • The Business Auto Coverage Form (ISO CA 00 01) is the standard commercial auto contract and uses covered-auto designation symbols (1-9) instead of a VIN list to define which autos a coverage reaches.
  • Symbol 1 (Any Auto) is the broadest and is the standard choice for liability because it blankets owned, hired, and non-owned exposure with no gaps.
  • Symbols 8 (hired) and 9 (non-owned) are gap-fillers; students must not reverse them — hired means the business pays to use the auto, non-owned means an employee's own car.
  • Automatic newly-acquired-auto coverage runs 30 days and applies only under Symbols 2, 3, or 4 for the matching auto type; Symbol 7 gives no automatic coverage.
  • Each coverage line on the declarations carries its own symbol, so liability is commonly Symbol 1 while physical damage is Symbol 7 or 2.

What the Business Auto Coverage Form Is

The Business Auto Coverage Form, ISO form CA 00 01, is the standard contract used to insure cars, trucks, and vans owned, hired, or used by a business. Combined with the Common Policy Declarations, the Business Auto Declarations (CA DS 03), and the Common Policy Conditions, it becomes the Business Auto Policy (BAP) — the commercial counterpart to the Personal Auto Policy (PAP).

Unlike the PAP, which lists each vehicle by VIN, the BAP must adapt to a fleet that constantly changes. A business may own zero, five, or five hundred vehicles, and also rent and borrow others. To solve this, the BAP uses covered-auto designation symbols that describe categories of autos rather than individual vehicles.

How the Form Is Built

The BAP is modular — a coverage is activated only when a symbol and a limit appear on the declarations.

SectionFunction
Declarations (CA DS 03)Named insured, policy period, limits, and symbols selected
Section I – Covered AutosDefines the nine symbols and the 30-day newly-acquired rule
Section II – Covered Autos LiabilityThird-party bodily injury and property damage
Section III – Physical DamageComprehensive, collision, specified causes of loss
Section IV – ConditionsLoss conditions and general conditions
Section V – Definitions'Accident,' 'auto,' 'bodily injury,' 'loss'

Because each coverage line carries its own symbol box, liability can be written far broader than physical damage on the very same policy.

The Nine Covered-Auto Designation Symbols

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 rigs
5Owned Autos Subject to No-FaultActivates PIP automatically in no-fault states
6Owned Autos Subject to Compulsory UMActivates UM automatically where required
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: Symbols 5 and 6 are NOT vehicle categories — they automatically pick up state-mandated coverages on owned autos. Symbol 5 triggers no-fault/PIP; Symbol 6 triggers compulsory uninsured motorist coverage.

Why Liability and Physical Damage Use Different Symbols

  • Liability is usually Symbol 1 so no auto can hurt a third party without coverage.
  • Physical damage is usually Symbol 7 or 2 because the insurer must know the year, make, model, and value to rate the risk and pay a loss. Blanket Symbol 1 physical damage is rarely offered.

The two gap-fillers complete the picture: Symbol 8 (hired) covers rentals and leased units, and Symbol 9 (non-owned) covers the employer's vicarious liability when employees drive their own cars on business. Reversing 8 and 9 is one of the most common student errors — hired means the business pays to use it; non-owned means it neither owns nor hires it.

The 30-Day Newly-Acquired-Auto Rule

Automatic coverage for a vehicle bought mid-term depends entirely on the symbol:

Symbol on the CoverageNewly Acquired Auto?
2 (all owned)Auto-covered 30 days, any type
3 (owned PP)Auto-covered 30 days IF private passenger
4 (owned other than PP)Auto-covered 30 days IF truck/van
7 (specifically described)NO automatic coverage — must endorse first

Worked example: A contractor's BAP shows Symbol 4 for liability and Symbol 7 for physical damage. He buys a dump truck and crashes it on day 10. Liability follows (Symbol 4, within 30 days), but physical damage does NOT — Symbol 7 reaches only scheduled units, and the truck was never added. The contractor pays for the truck's own damage out of pocket.

Who Is an Insured

The BAP's insured definition is broad and works in three tiers:

  • 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, limited to that liability (for example, an employer liable for an employee's covered driving).

The key carve-out: the owner of a hired or borrowed auto is generally NOT an insured (a rental company is not an insured under your BAP), and an employee is not an insured for liability while driving the employee's OWN auto — the employer relies on Symbol 9 for its own vicarious liability while the employee's personal policy is primary.

Rating, Fleet Status, and Audit

Commercial auto is fleet-rated or non-fleet (schedule) rated depending on the number of self-propelled power units. A risk with five or more owned power units is generally treated as a fleet and rated as a group; smaller risks are non-fleet and rated per vehicle. Primary rating factors include territory, vehicle classification (size/use/radius of operation), and the driver record.

The premium shown at inception is a deposit premium. Because vehicles are added and deleted mid-term, many BAPs are auditable, with the final premium adjusted at expiration based on actual exposure. Knowing the modular declarations, the symbol mechanism, the broad insured tiers, and the audit process is foundational to every commercial-auto question on the exam.
