Key Takeaways
Covered-auto symbols apply separately to each selected coverage.
Symbol 1 means any auto; Symbol 7 concerns specifically described autos with conditional newly acquired protection.
Hired and nonowned autos have different definitions and insured-person rules.
Physical damage, cargo and trailer interchange are separate grants.
MCS-90 addresses qualifying final public-liability judgments under its federal terms, with specified reimbursement rights.
Business Auto Symbols, Insureds and Physical Damage
Note
Commercial auto risks present unique operational exposures ranging from delivery vans to long-haul hazardous cargo motor carriers. Standard ISO commercial auto contracts use specialized numerical symbols and federal regulatory endorsements that every claims adjuster must master.
The standard commercial automobile policy is built around the Business Auto Coverage Form (BACF - ISO Form CA 00 01). Unlike personal auto policies where vehicles are generally identified on the Declarations page, commercial policies use Covered Auto Designation Symbols to tailor coverage for complex, shifting vehicle fleets.
Structure of the Business Auto Coverage Form
The standard BACF (CA 00 01) contains five primary sections:
- Section I — Covered Autos: Defines the numerical symbols (1–9 and 19) indicating which autos are covered under each coverage part.
- Section II — Covered Autos Liability Coverage: Third-party bodily injury and property damage insuring agreement, defense duties, and exclusions.
- Section III — Physical Damage Coverage: First-party property protection (Comprehensive, Specified Causes of Loss, Collision, and Towing).
- Section IV — Business Auto Conditions: Subrogation, appraisal, cancellation, duties after loss, and other insurance rules.
- Section V — Definitions: Defines key operational terms such as auto, bodily injury, property damage, mobile equipment, and pollutants.
Covered Auto Designation Symbols Matrix
Numerical symbols displayed next to each coverage on the Business Auto Declarations page define precisely which vehicles qualify as "covered autos" for that specific coverage:
| Symbol | Designation | Coverage Scope & Commercial Application |
|---|---|---|
| 1 | Any Auto | Broadest liability coverage available. Encompasses owned, hired, borrowed, and non-owned autos. Used exclusively for liability coverage; cannot be used for physical damage. |
| 2 | Owned Autos Only | Covers all autos owned by the named insured, including newly acquired autos. Automatically covers owned trailers designed to be pulled by covered vehicles. |
| 3 | Owned Private Passenger Autos Only | Covers only private passenger type autos (sedans, SUVs) owned by the named insured. Excludes commercial trucks, vans, and tractors. |
| 4 | Owned Autos Other Than Private Passenger | Covers commercial trucks, vans, tractors, and service vehicles owned by the insured. Excludes private passenger cars. |
| 5 | Owned Autos Subject to No-Fault | Covers owned autos licensed or garaged in states requiring personal injury protection (PIP) or statutory no-fault benefits. |
| 6 | Owned Autos Subject to Compulsory UM Law | Covers owned autos licensed or garaged in states where Uninsured Motorist coverage cannot be rejected by law. |
| 7 | Specifically Described Autos Only | Most restrictive symbol. Covers only autos explicitly listed and described on the declarations schedule with VIN and premium. |
| 8 | Hired Autos Only | Covers autos leased, hired, rented, or borrowed by the named insured for business. Excludes vehicles borrowed/hired from employees or partners. |
| 9 | Non-Owned Autos Only | Covers autos used in the insured's business that are not owned, leased, hired, or borrowed by the insured (e.g., employee vehicles on company errands). |
| 19 | Mobile Equipment Subject to Motor Vehicle Laws | Covers land vehicles meeting the definition of mobile equipment that are subject to motor vehicle registration or financial responsibility laws. |
Symbol 7 Rules for Newly Acquired Autos
Under Symbol 7 (Specifically Described Autos Only), newly acquired vehicles are covered only under two strict conditions:
- The insurer already insures all owned autos of the named insured, or the newly acquired auto replaces an auto previously scheduled on the Declarations; AND
- The named insured asks the insurer to insure the newly acquired auto within 30 days after acquisition.
Important
If an insured carrying Symbol 7 acquires a new commercial vehicle and fails to notify the insurer within 30 days, any claim arising on or after day 31 is completely excluded from coverage.
The Operational Distinction Between Symbol 8 and Symbol 9
Adjuster exam questions routinely test the difference between Symbol 8 and Symbol 9:
- Symbol 8 (Hired Autos Only): Covers vehicles the business rents from third-party rental agencies (e.g., Enterprise, Hertz) or leases under commercial equipment contracts. It explicitly excludes vehicles owned by employees.
- Symbol 9 (Non-Owned Autos Only): Protects the business entity when employees, partners, or members drive their personal vehicles while running company errands, meeting clients, or traveling for work. It provides vicarious liability protection for the employer, but does not provide liability coverage for the employee driver personally (the employee's personal auto policy remains primary).
BACF Section II: Covered Autos Liability Coverage
Under Section II, the insurer agrees to pay all sums an insured legally must pay as damages because of bodily injury or property damage caused by an accident resulting from the ownership, maintenance, or use of a covered auto.
Who Is an Insured Under the BACF?
- The Named Insured: Fully covered for any covered auto designated by the applicable symbol.
- Permissive Users: Anyone using a covered auto with permission, except:
- The owner of a hired or borrowed auto (e.g., the rental company or an employee who owns the vehicle).
- An employee of the insured if the covered auto is owned by that employee or a member of their household.
- Anyone working in an auto business (repair, servicing, parking).
- Vicarious Liability Entities: Anyone liable for the conduct of an insured, to the extent of that liability.
Critical BACF Exclusions
Section II contains several exclusions that claims adjusters evaluate daily:
- Expected or Intended Injury: Injury or damage intentionally caused by the insured.
- Contractual Liability: Liability assumed under contract, unless it qualifies as an "insured contract" (such as a standard commercial vehicle lease agreement).
- Workers' Compensation & Employer's Liability: Work-related injuries to employees are barred from commercial auto liability.
- The Fellow Employee Exclusion: Bodily injury to any fellow employee of the insured arising out of and in the course of employment is excluded. If Employee A accidentally runs over co-worker Employee B on a jobsite, the standard BACF excludes liability coverage for Employee A. A suitable endorsement may modify this exclusion; it is not a universal statutory requirement to attach one named form.
- Care, Custody, or Control: Property damage to cargo or property owned, transported by, or in the care, custody, or control of the insured (covered under Inland Marine Motor Truck Cargo forms).
- The Pollution Exclusion & The Operating Fluids Exception: The BACF broadly excludes pollution discharges. However, the policy contains a vital exception:
Note
The pollution exclusion does NOT apply to fuels, lubricants, hydraulic fluids, or exhaust gases that are needed for or result from the normal mechanical or electrical functioning of the covered auto, provided the discharge results directly from an auto accident (e.g., motor oil or diesel fuel leaking from a ruptured vehicle tank onto the roadway after a crash).
BACF Section III: Physical Damage Coverage
The BACF offers three primary physical damage options:
- Comprehensive: Covers loss from any cause except collision with another object or overturn.
- Specified Causes of Loss: A lower-cost alternative to Comprehensive, covering direct loss caused strictly by:
- Fire, lightning, or explosion
- Theft
- Windstorm, hail, or earthquake
- Flood or water damage
- Mischief or vandalism
- Sinking, burning, collision, or derailment of any conveyance transporting the covered auto
- Collision: Covers overturn or collision with another object.
- Towing & Labor: Provides reimbursement for towing and labor performed at the site of disablement for private passenger type autos.
The Motor Carrier Act of 1980 & Financial Responsibility Tiers
Federal motor-carrier financial responsibility under 49 CFR Part 387 depends on operating status, commodity, vehicle weight and the particular rule. Ordinary for-hire interstate property carriers meeting the rule commonly have a $750,000 minimum; hazardous classifications have specified higher requirements. Do not assign a universal tier merely from the word hazardous or assume every private local delivery van has the same requirement.
This public financial-responsibility framework differs from physical damage on a tractor, trailer interchange and cargo insurance. Verify the applicable federal classification and current table before advising on a carrier's required limit.
The MCS-90 Endorsement: Structure & Legal Mechanics
MCS-90 is the federally prescribed public financial-responsibility endorsement. Within its terms, it requires satisfaction of a final judgment against the named motor carrier for public liability resulting from negligence in operating, maintaining or using motor vehicles subject to the federal requirements. An unscheduled vehicle or underlying policy defense may not eliminate this public obligation.
Its scope, insured definition, cancellation and required final judgment matter. It does not create a defense duty or ordinary cargo/first-party equipment insurance, and an accident involving a truck is not alone sufficient to establish application. The endorsement retains the underlying policy terms between insurer and insured and provides reimbursement for payments the insurer would not owe except for the endorsement.
For a qualifying final judgment, separately calculate the obligation under the policy and the obligation under MCS-90. Obtain authorized coverage review; do not describe the endorsement as unlimited payment for every driver, every settlement or every type of property damage. Source: FMCSA MCS-90.
An electrical contracting company carries a Business Auto Coverage Form with Symbol 7 listed for liability coverage. Two weeks after the policy inception date, the company purchases an additional service van but does not notify the insurer until 45 days later. If the new van is involved in an accident on day 40, how will the insurer respond under Section I of the BACF?
The claim is fully covered because newly acquired commercial autos are automatically granted 60 days of retroactive coverage
The claim is covered under the supplementary payments provision regardless of reporting timelines
The claim is covered only if the company owner was driving at the time of the loss
The claim is denied because newly acquired vehicles under Symbol 7 must be reported to the insurer within 30 days of acquisition
Which Covered Auto Designation Symbol provides coverage for employee-owned vehicles when driven by employees on company business, such as running errands or visiting client sites?
Symbol 9 (Non-Owned Autos Only)
Symbol 8 (Hired Autos Only)
Symbol 2 (Owned Autos Only)
Symbol 19 (Mobile Equipment Subject to Motor Vehicle Laws)
What does MCS-90 primarily address?
Ordinary first-party cargo loss
Payment of every truck settlement without conditions
Unlimited garagekeepers damage
Qualifying final public-liability judgments under its federal terms, with reimbursement for payments outside the underlying policy
