If the other driver caused the crash, the cost of a rental car while your car is fixed is part of your property damage claim, the same as the repair bill itself. This is called loss of use, and it is not a courtesy the insurance company extends because it likes you. The rental usually runs from the day you report the loss until the repair is finished or a total-loss offer is made, plus a short window to find another car. If the company cuts the rental off before either of those things happens, that is a dispute you can push back on, and there is a specific regulation that gives you the deadline to push against.
The harder part is the gap between what should happen and what does happen. Repair shops run behind schedule. Insurance companies set an internal cap on rental days that has nothing to do with how long your particular repair takes. Parts get backordered. None of that changes who owes for the car you need in the meantime, but it does mean you often have to say so, in writing, more than once.
Loss of use is part of the property damage claim
When another driver damages your car, California law treats the loss of the use of that car as part of your damages, alongside the cost to fix it. You did not choose to be without a car. The at-fault driver’s insurance company owes you a comparable replacement, generally a similar class of vehicle, for the period you are without your own.
That obligation exists whether or not the company mentions it. Some claims examiners set up a rental authorization the same day they accept fault. Others wait to be asked. Ask on the first call, get the rental authorization number in writing, and confirm which rental company it applies to before you drive off the lot. Our guide on what to do if your property damage claim is denied covers the broader dispute process if the company balks at any part of this.
How long the rental typically runs
For a repairable car, the rental should run from the day you report the loss through the day the shop finishes the work, plus a reasonable number of days to pick the car up. Insurance companies commonly authorize the rental in blocks, seven or fourteen days at a time, and extend it when the shop documents that the repair is still in progress. Keep the shop’s repair order and any supplement paperwork, since that is the proof that ties the rental days to the actual work rather than to a guess about the timeline.
A total loss changes the calculation. Once the company makes a written total-loss offer based on the vehicle’s actual cash value, it generally continues the rental for a short additional period, often a matter of days, to give you time to accept the offer, negotiate the valuation, or shop for a replacement car. After that window closes, the rental stops even if you have not yet bought another car. If you disagree with the actual cash value the company offered, our article on calculating diminished value in California explains the related but separate issue of what a repaired car is worth after the fact, which sometimes comes up in the same claim.
None of these are fixed statutory numbers. They are industry practice, and practice varies by company and by claims examiner. What does not vary is the underlying obligation: you are entitled to a comparable vehicle for a reasonable period tied to how long the repair or the total-loss process takes rather than to an arbitrary internal cap.
A rental clock that seems to run on its own schedule is usually not a coincidence. Some companies set an initial authorization for a fixed number of days regardless of the repair estimate, expecting the shop or the customer to ask for an extension when the work runs longer. That is a workable system as long as someone asks. It becomes a problem only when the extension request gets ignored, and the way to keep that from happening is to put every extension request in writing rather than relying on a phone call the company has no record of.
Your own rental reimbursement coverage is the faster route
If you carry rental reimbursement coverage on your own policy, use it while the fault dispute gets sorted out. Your insurer pays for the rental up to your policy’s daily and total limits, and then seeks reimbursement from the at-fault driver’s company later, a process called subrogation. This route is usually faster because you are not waiting on another company to accept liability first.
The tradeoff is the daily limit. Many policies cap reimbursement at a modest daily amount, which may not cover a larger vehicle or a longer rental period. Check your declarations page before the crash if you can, and immediately after if you cannot. If your own coverage runs out before the at-fault company has accepted the claim, that is the moment to escalate the claim on the other side rather than pay out of pocket.
What to do when the rental gets cut off before the car is fixed
This happens more than it should. The rental authorization ends on a date the company picked, the shop is not finished, and the rental counter tells you the reservation will not extend without a new authorization number.
Here is the order to work through it.
- Call the shop and get the estimated completion date in writing, by email or text if the shop will send it.
- Send that date to the claims examiner handling your file and ask for a written extension of the rental authorization to match it.
- If the company refuses or goes silent, put the request in writing yourself, by email, and keep a copy.
- Reference the Fair Claims Settlement Practices Regulations. California requires an insurance company to accept or deny a properly submitted claim, or a specific part of a claim like a rental extension, within 40 days of receiving proof of the claim (10 CCR 2695.7). A company that goes quiet past that point is out of compliance with its own regulatory obligations.
- If the company still will not extend the rental and the shop still has your car, ask your own insurer about rental reimbursement coverage as a bridge, even temporarily, while the dispute with the other company continues.
- Keep every rental receipt and every day of the repair timeline. If you end up paying out of pocket for part of the gap, that amount belongs in the demand later.
A short gap of a day or two, caused by a genuine miscommunication, is common and usually gets fixed with one phone call. A pattern of the company letting the authorization lapse every time it is close to expiring is different, and you should document it in writing rather than accept it as normal.
Rental counters in the Valley
Most people picking up a rental after a crash are not choosing a company for its brand loyalty program. They are choosing whichever counter has a car available and is close to the body shop. Enterprise and Hertz both operate locations near Northridge and Van Nuys, and either one can process an insurance-authorized rental once you have the claim number and authorization in hand. We are not endorsing one company over the other. Bring your driver’s license, the authorization number, and a form of payment for the deposit hold, which the at-fault company’s authorization does not always cover.
If the crash happened near our Northridge area, ask the shop which rental counter they work with most often. Shops that deal with the same rental locations repeatedly tend to have a faster handoff, which shortens the number of days you spend without a car in either direction.
The same is true on the Van Nuys side of the Valley, where several of the larger body shops along Sherman Way and Van Nuys Boulevard send customers to the same handful of counters. A shop that already has a working relationship with the rental location can often get the reservation confirmed the same day, which matters most in the first 48 hours after a crash, when you are trying to get to work and to your doctor without your own car.
Keep every receipt
This is the least glamorous part of a property damage claim and the most commonly skipped. Keep the rental agreement, every extension, every receipt for gas if the agreement requires a full tank on return, and any out-of-pocket days you paid because the authorization lapsed. If the claim later needs to be pushed further, whether that is a supplement to the property damage file or, in a case with an injury component, part of a larger demand, the rental documentation is the easiest piece of the file to prove and the easiest piece to lose track of if you do not save it as you go.
Key points
- Loss of use, the cost of a rental car, is part of your property damage claim when the other driver is at fault.
- The at-fault insurer’s rental should run until the repair is finished or a total-loss offer is made, plus a short window afterward.
- Your own rental reimbursement coverage is usually the faster path while fault gets sorted out, subject to your policy’s daily limit.
- A company that lets the rental authorization lapse past 40 days without a response is out of step with the Fair Claims Settlement Practices Regulations (10 CCR 2695.7).
- Get the shop’s completion estimate in writing and send it to the claims examiner before the current authorization runs out.
- Save every rental receipt from day one.
Frequently asked questions
Do I have to use the rental company the insurance company picks?
No. You can use any rental company, though the authorization number and any direct-billing arrangement usually apply only to the company the insurance company set up. If you use a different counter, confirm in writing that the daily rate and authorization still apply, or you may end up paying the difference.
What if the repair takes much longer than expected because of backordered parts?
Send the shop’s documentation of the delay to the claims examiner and ask for a corresponding extension. Parts delays are common and are not your fault, and a well-documented delay is one of the easier rental extensions to get approved.
Can I get a bigger or nicer rental than my own car?
Generally you are entitled to a comparable vehicle, similar class and size to your own, rather than an upgrade. If your car is a compact sedan, expect a compact sedan rental. Ask about the specific class before you pick up the car so there is no surprise at the counter.
What if I was partly at fault for the crash?
Loss of use still applies, but the amount may be reduced by your share of fault under California’s comparative negligence rule. Our page on car accident claims explains how shared fault affects a claim generally, and a claim with disputed fault is a good reason to get a second opinion before you accept a partial denial of the rental.
