Loss of Use: The Money You're Owed Even Without a Rental

Carriers treat these as interchangeable. They are not. Rental reimbursement is a benefit under your own policy — it pays for a substitute vehicle while yours is repaired. Loss of use is a separate damages claim against the at-fault driver (or their insurer) for the value of being deprived of your car. One is a policy benefit. The other is a tort remedy.

That distinction matters because carriers routinely hand you a rental authorization and consider the matter closed. It is not closed. If you declined the rental — because you had a loaner, caught rides, or simply couldn't deal with the logistics — the at-fault carrier still owes you the equivalent daily value of a comparable vehicle for every day you were without yours. Under R590-190-11(9)(a), substitute transportation is owed as part of a complete third-party settlement. No receipt required.

Do not let an adjuster tell you that declining a rental waives your loss of use. That framing serves one party — and it is not you.

The standard for loss of use is the reasonable rental rate for a comparable vehicle in your market. If you drove a 2022 truck, the rate is pegged to what it costs to rent that class of vehicle locally — not a compact economy car. Carriers default to the cheapest comparable rate they can find. Sometimes they use national averages that don't reflect Utah's market at all.

A defensible daily rate typically runs $45–$120 per day depending on vehicle class. Multiply that by the number of days your vehicle sat in repair or was held pending a total loss decision, and the number adds up fast. A 30-day repair cycle on a midsize SUV at $75/day is $2,250 — and carriers often offer nothing without being pushed. The coverage authority on the at-fault side is R590-190-11(9)(a), which requires substitute transportation as part of a fair third-party resolution.

The period also matters. Loss of use runs through the completion of repairs on a repair claim. On a total loss, it runs through a reasonable replacement window — the time it takes to find and purchase a comparable vehicle. Carriers cut the clock the moment they issue a total loss offer. That is not how the law measures it.

On a total loss, the at-fault carrier is required under R590-190-11(2)(a) to pay the cost of a comparable replacement vehicle, including taxes, license, and transfer fees. That is the ACV floor. Loss of use layers on top of that — it compensates you for every day between the date of loss and the date you could reasonably complete a replacement purchase.

Carriers routinely terminate rental coverage the moment they issue a settlement offer — before you've signed anything, before you've had time to shop, before the check clears. That cutoff is premature. The reasonable replacement window in Utah's market, depending on vehicle type and inventory, can run two to four weeks after an offer is made. That's $630–$3,360 in additional loss of use at common daily rates that carriers simply don't volunteer.

If you are past the offer stage and the rental has been cut off, you are not out of options. Third-party claims against the at-fault driver's carrier have a four-year deadline under §78B-2-307(3). You have time to push back — but do it before that window closes.

Document every day you were without your vehicle. Dates in the shop. Dates waiting on a total loss decision. Dates searching for a replacement. That timeline is your claim. Pair it with a local daily rate for a comparable vehicle and you have a concrete number the carrier has to answer.

If the carrier stonewalls, that behavior falls under §31A-26-303 — Utah's unfair claim settlement practices statute. Failing to pay a clearly owed element of damages, or misrepresenting what is owed, is not just aggressive negotiating. It is a statutory violation with consequences.

At Property Damage Pros, our in-house legal team handles exactly this. We calculate your total loss or diminished value using all major book valuations, actual dealer sales data, auction data, and dealer inventory demand data — not one source, not the carrier's preferred tool. Our flat fee is $350 for total loss appraisals and $400 for diminished value. Or work on contingency — you pay nothing unless we beat the insurer's initial offer. Our average total loss recovery is $6,500 above the initial offer. Loss of use is part of that fight.
