Warning! A plain vanilla Commercial Auto Policy (sometimes referred to as a Business Auto Policy) does not serve as a substitute for a Personal Auto Policy. Unless you're in a company car on business, the Commercial Auto Policy doesn't cover liability and medical payments. This is not a cruel trick; it protects your company from liability for non-business accidents.
If you insure your auto under a Personal Auto Policy, you and your family have liability coverage and medical payments for non-business accidents.
Can the Commercial Auto Policy be endorsed to function like a Personal Auto Policy? Yes, there are two drive other car (DOC) endorsements to effect this change. One is for corporations and the other is for unincorporated businesses. Your agent can arrange the proper endorsement for your needs. However, don't avoid a Personal Auto Policy just to save premiums, or for tax reasons.
Generally, a Personal Auto Policy can suffice for a sole proprietor with private passenger-type vehicles only. A private passenger vehicle owned or leased by a corporation, partnership or other business organization is a different story. You must use a Commercial Auto Policy.
Symbols and the Commercial Auto Policy
The Commercial Auto Policy uses symbols 1 through 9 to indicate vehicle coverage for claims. Symbol 1 gives any auto coverage. The insured is covered for owned, rented, borrowed autos and an auto just used by the insured. This is the broadest coverage available on the Commercial Auto Policy, and is what most business owners select when it's available.
Symbol 7, the other most common symbol, covers only specifically described autos that are listed on the policy. Newly acquired autos, under symbol 7, are given coverage only if the insurer insures all owned autos. Symbol 7 also covers a new vehicle that replaces a covered one. This feature only works if the acquired auto is identified to the insurance company within 30 days.
Combining Symbol 8 & 9 will provide coverage for hired, leased, rented or borrowed autos and non-owned autos. That's good for a business that doesn't own an auto.
