Commercial Auto Insurance

A guide to commercial auto insurance: what it covers, what it excludes, what actually goes wrong, what reduces it, and what an underwriter asks. Every statement cites a published source.

Overview

What this line is, and who or what it is designed to protect.

The coverage part that responds when a vehicle used in a business injures someone or damages their property. On the standard form it is built differently from every other commercial line: the policy does not cover "your vehicles" as a category, it covers whichever autos the numbered symbols on the declarations page designate for each individual coverage. Two businesses holding the same form with the same limit can therefore have entirely different coverage, and the difference is readable only in Item Two of their declarations [1].

  • A business against sums it legally must pay as damages for bodily injury or property damage arising out of the ownership, maintenance or use of a covered auto [1]

  • Employees and others driving with permission, where they fall inside the Who Is An Insured provision and outside its five stated exceptions [1]

  • The business against defence costs, which the insurer has a duty to pay for suits seeking damages the insurance applies to [1]

  • A business that hires or borrows vehicles, but only if a hired-autos symbol is shown for that coverage [1]

  • A business whose employees drive their own cars on its behalf, but only if a non-owned symbol is shown for that coverage [1]

    • Symbol 9 is Non-owned Autos Only: only those autos you do not own, lease, hire, rent or borrow that are used in connection with your business, and it includes autos owned by your employees, partners or members, or members of their households, but only while used in your business or your personal affairs.
    • The Covered Autos Liability Coverage insuring agreement states that the insurer will pay all sums an insured legally must pay as damages because of bodily injury or property damage to which the insurance applies, caused by an accident and resulting from the ownership, maintenance or use of a covered auto.
    • The same insuring agreement covers sums an insured legally must pay as a covered pollution cost or expense caused by an accident, but states that the insurer will only pay for the covered pollution cost or expense if there is also bodily injury or property damage to which the insurance applies caused by the same accident.
    • The form states that the insurer has no duty to defend any insured against a suit seeking damages for bodily injury, property damage or a covered pollution cost or expense to which the insurance does not apply.
    • The form states that the duty to defend or settle ends when the Covered Autos Liability Coverage Limit of Insurance has been exhausted by payment of judgments or settlements.
    • Who Is An Insured at Paragraph A.1. lists as insureds: you for any covered auto; and anyone else while using with your permission a covered auto you own, hire or borrow, subject to five stated exceptions.
    • The first exception to Who Is An Insured removes the owner or anyone else from whom you hire or borrow a covered auto, and states that the exception does not apply if the covered auto is a trailer connected to a covered auto you own.
    • The second exception removes your employee if the covered auto is owned by that employee or a member of his or her household.
    • The third exception removes someone using a covered auto while he or she is working in a business of selling, servicing, repairing, parking or storing autos, unless that business is yours.
    • The fifth exception removes a partner, if you are a partnership, or a member, if you are a limited liability company, for a covered auto owned by him or her or a member of his or her household.
    • Who Is An Insured also includes anyone liable for the conduct of an insured described above, but only to the extent of that liability.
    • Exclusion 2 Contractual removes liability assumed under any contract or agreement, but states the exclusion does not apply to liability for damages assumed in a contract or agreement that is an insured contract, provided the bodily injury or property damage occurs subsequent to the execution of the contract, or that the insured would have in the absence of the contract.
    • Exclusion 3 Workers' Compensation removes any obligation for which the insured or the insured's insurer may be held liable under any workers' compensation, disability benefits or unemployment compensation law or any similar law.
    • Exclusion 4 Employee Indemnification And Employer's Liability removes bodily injury to an employee of the insured arising out of and in the course of employment by the insured or performing duties related to the conduct of the insured's business, and to the spouse, child, parent, brother or sister of that employee as a consequence.
    • Exclusion 4 states that it applies whether the insured may be liable as an employer or in any other capacity, and to any obligation to share damages with or repay someone else who must pay damages because of the injury.
    • Exclusion 1 Expected Or Intended Injury removes bodily injury or property damage expected or intended from the standpoint of the insured.
    • Supplementary Payments include all expenses the insurer incurs and up to $2,000 for the cost of bail bonds, including bonds for related traffic law violations, required because of an accident the insurer covers, and the form states the insurer does not have to furnish these bonds.
