12.1 Business Auto Coverage Form and Covered Auto Symbols

The Business Auto Coverage Form

The Business Auto Coverage Form (ISO form CA 00 01) is the workhorse of commercial auto insurance. It is combined with the Commercial Auto Declarations (CA DS 03) and the Common Policy Conditions/Declarations (IL forms) to create a complete Commercial Auto Coverage Part. The current widely used edition is CA 00 01 11 20 (November 2020). On the exam, the Business Auto policy is contrasted with the Personal Auto Policy (PAP): it covers entities (corporations, partnerships, LLCs) rather than named individuals and their resident family members.

The form is organized into five sections you must memorize:

• Section I — Covered Autos (defined by symbols)
• Section II — Covered Autos Liability Coverage
• Section III — Physical Damage Coverage
• Section IV — Business Auto Conditions
• Section V — Definitions

Unlike the PAP, the Business Auto Form uses a single Combined Single Limit (CSL) for liability by default rather than split limits, though split limits can be added by endorsement.

Covered Auto Symbols

The single most-tested concept is the covered auto symbol system. A symbol number is entered next to each coverage on the declarations to define which autos that coverage applies to. The symbols are numbered 1 through 9 (plus 19 for mobile equipment subject to compulsory/financial responsibility laws).

Exam trap: Symbol 1 (Any Auto) is the broadest and is available only for liability, not for physical damage. Physical damage requires the insurer to know which specific units it is insuring, so symbols 2, 3, 4, 7, 8, or 19 are used for Comprehensive and Collision.

How Symbols Build Coverage

Symbols are additive. To cover hired and non-owned exposures along with owned autos, an insured commonly uses symbols 2, 8, and 9 together on the liability line. A retailer with only a few delivery vans that wants the leanest coverage might use symbol 7 (specifically described autos) so coverage attaches only to scheduled VINs.

Worked example: A contractor owns 6 trucks (specifically scheduled), rents a crane truck for one job, and has employees who run errands in personal cars. To cover all three exposures for liability, the producer enters symbols 7, 8, and 9. If the contractor instead wanted automatic coverage on any newly acquired truck without reporting it, symbol 2 (owned autos) would be preferable to symbol 7 because newly acquired autos are automatically covered for 30 days under owned-auto symbols.

Newly acquired auto rule: Under symbols 1, 2, 3, or 4, an auto acquired during the policy period is automatically covered. The insured must report it within 30 days only if it is the first auto of its kind and physical damage applies.

The Numbered Auto Symbols — Memorize Each

Commercial auto coverage scope is set by covered-auto symbols entered next to each coverage on the declarations. The exam expects the standard ISO Business Auto symbols:

How Symbols Build a Coverage Package

The most protective liability programming uses Symbol 1 (Any Auto) for liability, which automatically picks up newly acquired, hired, and non-owned autos without scheduling. For physical damage, an insurer will not write "any auto" (it cannot insure cars it does not know exist), so physical damage is usually written with Symbol 7 (specifically described), often combined with 8 (hired) and 2/3/4 (owned). A common exam pattern: liability under Symbol 1 but collision/comprehensive under Symbol 7 — the business is liable for any auto it operates but only repairs the scheduled units.

Hired and Non-Owned Exposure

Hired autos (Symbol 8) are vehicles the business leases, hires, rents, or borrows (not from employees). Non-owned autos (Symbol 9) are autos owned by employees or others used in the business — covering the business's vicarious liability when an employee runs a work errand in a personal car. Together, Symbols 8 and 9 close the gap that exists if only owned autos (Symbol 2) are covered; a delivery business that lets staff use personal cars must add Symbol 9 or face uninsured vicarious liability.
