Non-owner auto policy vs standard auto policy

A personal auto policy is built around a list of vehicles. The declarations page names the cars, and the coverage for liability, physical damage and medical costs is organised around them and the people in the household who drive them. People who do not own a car still drive, though. They borrow a friend's truck, rent a car on a trip, drive a relative's vehicle occasionally or need to keep proof of insurance on file with the state after a violation.

A named non-owner policy exists for those drivers. It provides liability coverage that travels with the person rather than with a vehicle. It is inexpensive relative to a standard policy because it leaves out several coverages and assumes the driver has no regular access to any car. Those assumptions are exactly where people get into trouble.

What a standard auto policy covers

A standard policy insures the vehicles listed on it and any newly acquired vehicle for a short period. It provides bodily injury and property damage liability, and optionally uninsured and underinsured motorist coverage, medical payments or personal injury protection, comprehensive, collision, rental reimbursement and roadside coverages. The named insured, a resident spouse and resident relatives are covered while driving the listed cars, and anyone driving them with permission is generally covered as well.

A standard policy also usually extends liability and often physical damage coverage to the named insured when driving a car they do not own, such as a rental or a borrowed vehicle, provided that car is not furnished for their regular use. That extension is why car owners seldom need a separate non-owner policy.

What a non-owner policy covers

A named non-owner policy covers the named individual for liability when driving a vehicle they do not own and that is not available for their regular use. Most forms also include uninsured motorist coverage and, where state law makes it part of every policy, personal injury protection. There is no vehicle on the declarations page and no comprehensive or collision coverage, so damage to the car being driven is not covered by the non-owner policy.

Coverage is typically excess over the vehicle owner's insurance. When a policyholder borrows a friend's car, the friend's policy pays first up to its limits, and the non-owner policy pays after it. On a rental, the rental company's own liability protection, if any, may be primary, and the non-owner policy stands behind it. A non-owner policy can also carry an SR-22 or similar filing, which is one of its most common uses.

The mechanism that actually differs

The first difference is what the policy attaches to. A standard policy attaches to vehicles and extends to people; a non-owner policy attaches to one person and extends to vehicles they occasionally drive. The second is the order of payment. On a car you own, your standard policy is primary. On a borrowed car, the owner's policy is primary and a non-owner policy is excess, which makes the non-owner premium lower because it pays only after someone else's coverage is exhausted.

The third is the exclusion for vehicles owned by or furnished for the regular use of the insured or anyone in the household. A non-owner policy is not a cheap way to drive a household car, a partner's car driven every day or a company vehicle assigned to the driver. Those vehicles need the driver listed on the policy that insures them, and a claim involving one of them on a non-owner policy is likely to be denied.

A worked borrowed-car claim

Suppose a driver in Las Vegas has sold her car, commutes by bus and rideshare, and borrows a friend's sedan a few times a month. She buys a non-owner policy with bodily injury limits of $100,000 per person and $300,000 per accident for about $450 a year. The friend's policy carries limits of $25,000 per person. While driving the friend's car, she runs a red light and injures another driver, whose claim settles at $90,000. The friend's policy pays its $25,000 limit first, and her non-owner policy pays the remaining $65,000. Damage to the friend's car is paid by the friend's collision coverage, if the friend has it, or by her personally.

Now suppose that a year later she moves in with a partner who owns a car and she begins driving it to work every day. For example, if she causes a similar crash in the partner's car, her non-owner carrier can decline because the car is both in her household and available for her regular use, and the partner's policy may resist too if she was never disclosed as a regular driver. The correct fix was to be added to the partner's policy when she moved in. The figures are illustrative.

Who each suits

The deciding question is whether the person owns a car or has one available to drive regularly.

• A person who owns and drives any vehicle needs a standard policy on it, and that policy already extends to occasional rentals and borrowed cars.
• A person who does not own a car but borrows or rents one from time to time can use a non-owner policy to carry their own liability limits rather than relying on someone else's.
• A person required to maintain an SR-22 filing without owning a car usually needs a non-owner policy to keep the filing active and a license valid.
• A person between cars, living abroad temporarily or relying on transit for a period can use a non-owner policy to avoid a lapse in insurance history, which affects future rates when they buy a car again.
• A person who drives a household member's or employer's car regularly needs to be listed on that vehicle's policy; a non-owner policy does not fit that situation.

Regional notes

Arizona, Nevada and Idaho are at-fault states, so a non-owner policy there is essentially liability and uninsured motorist protection for the driver. Utah is a no-fault state, and a policy written there includes personal injury protection for the insured's own injuries. Each state sets its own financial responsibility limits and its own SR-22 filing periods, and a non-owner filing in one state does not automatically carry over when a driver moves. Heavy rental volume around Las Vegas and Phoenix, university campuses in Tempe, Salt Lake City and Boise where students borrow cars regularly, and growing transit use in all four metros make non-owner coverage relevant to more drivers than it once was, provided the regular-use exclusion does not apply to how they actually drive.

When to keep what you have

A car owner with a standard policy that extends to non-owned vehicles does not need a separate non-owner policy, and should simply confirm that the liability limits are high enough to cover driving other people's cars, whose owners may carry low limits. A non-owner policyholder who still owns no car and has no regular access to one is also correctly placed. The situations to change are a non-owner policy held by someone who now drives a household or company vehicle daily, and a lapse in coverage after selling a car that could have been avoided. We look at how each driver in the household actually uses vehicles, quote the right structure across the carriers we represent in Arizona, Nevada, Utah and Idaho, and if the current policy fits, we say so.
