Renting a car should be the easy part of your trip. Then an accident happens, and suddenly you’re dealing with a rental company’s insurance adjuster, a police report, possible injuries, and questions you didn’t expect to face on a California highway. If you’ve found yourself in that situation in Santa Ana, this 2026 guide breaks down exactly what to do, step by step, and explains why the decisions you make in the first few hours matter more than most people realize.

Razavi Law Group has handled car rental accident cases across Orange County and throughout California, and the clients who come out ahead are almost always the ones who knew what to do at the scene before calling anyone.

Why Car Rental Accidents Are Different from Regular Car Accidents?

A car rental accident is not just a standard fender-bender with extra paperwork. Multiple parties may be legally involved: the rental company, the other driver, their insurer, your personal auto insurer, and potentially a credit card company if you declined the rental coverage. California law adds another layer, since the state has specific rules governing how liability is assigned in these situations.

Under the federal Graves Amendment (49 U.S.C. § 30106), rental companies are generally shielded from direct liability for accidents caused by renters, unless the company was negligent in maintaining the vehicle. California courts have applied this consistently. That means the financial burden typically falls on the renter’s own insurance, the rental company’s optional coverage, or the at-fault driver’s policy — depending on how the crash happened.

Understanding this framework before you take action can protect you from making statements or decisions that limit your options later. Justia’s California case law database is a useful reference if you want to read how these cases have played out in state courts.

Step One: Check for Injuries and Call 911

This sounds obvious, but people in shock often skip it. Check yourself and every passenger. If anyone is hurt — or even thinks they might be — call 911 immediately. California Vehicle Code Section 20008 requires drivers involved in accidents causing injury to file a report with the California Highway Patrol or local police within 24 hours.

In Santa Ana, the Santa Ana Police Department handles crash reports for accidents within city limits. The non-emergency line is separate from 911, but if there’s any injury at all, use 911 and wait for officers to arrive. Don’t move the vehicles unless they’re blocking traffic and creating a danger.

A police report becomes a critical document in your case. Adjusters and car accident attorneys rely on it to establish what happened before anyone’s memory fades or changes.

Step Two: Document Everything at the Scene

Take photos before anything is moved. Capture the damage to both vehicles, the position of the cars, road conditions, traffic signals, skid marks, and any visible injuries. If there are witnesses, get their names and phone numbers. Written contact information is better than relying on people to pick up calls later.

Exchange information with the other driver: name, license number, insurance information, and the vehicle registration. For a rental car, the registration will be in the glove box under the rental company’s name.

Do not apologize. Do not say you didn’t see the other car. Under California’s comparative fault rules, anything you say at the scene can be used to reduce your compensation later. Cornell Law School’s overview of comparative negligence explains how California’s pure comparative fault system works — even if you’re partially at fault, you may still recover damages.

Step Three: Notify the Rental Company

Call the rental company’s emergency line from the scene or as soon as possible after. Most major rental companies — Enterprise, Hertz, Avis, Budget — have 24-hour lines specifically for accidents. Check the rental agreement in the glove box for the number.

Report the accident factually. Say what happened, where it happened, and who was involved. Do not speculate about fault. The rental company will open a damage claim, and that process runs separately from any personal injury claim you may have.

If you declined the collision damage waiver (CDW) at the counter, your personal auto insurance or the credit card you used to book the rental may cover the vehicle damage. Most major credit cards that offer rental coverage require you to have declined the rental company’s own coverage. Review your card benefits before assuming you’re covered — the rules vary significantly.

Step Four: Seek Medical Attention Even If You Feel Fine

Adrenaline masks pain. Whiplash, soft tissue injuries, and concussions can take 24 to 72 hours to become obvious. In Orange County, there are urgent care clinics and emergency rooms throughout Santa Ana. Go to one the same day as the accident.

Medical records created close in time to the accident are far stronger evidence than records created days later. Insurers routinely argue that delayed treatment means the injury wasn’t serious or wasn’t caused by the crash. A car rental accident attorney will tell you the same thing: a gap in medical treatment gives adjusters a reason to reduce your claim.

California law gives you two years from the date of injury to file a personal injury lawsuit under California Code of Civil Procedure Section 335.1 — but building a strong case requires documentation starting from day one, not month twenty-three.

Step Five: Report to Your Own Insurance

California law requires you to report accidents to your insurer promptly. Check your policy for the specific deadline, but most require notice within a few days. Failing to report can give your insurer grounds to deny coverage.

When you call, stick to facts. You are not required to give a recorded statement to your own insurer without first speaking to an attorney, and you are not required to give one at all to the other driver’s insurer. FindLaw’s guide on dealing with insurance adjusters has practical information on protecting yourself during that process.

Step Six: Understand Who Covers What

Here’s where car rental accidents get genuinely complicated. You may be dealing with:

Your personal auto insurance (liability, collision, and medical payments coverage all apply differently). The credit card rental protection, which typically covers vehicle damage but not personal injury. The rental company’s loss damage waiver, if you purchased it. The other driver’s liability insurance, if they caused the crash. Uninsured/underinsured motorist coverage on your own policy, if the at-fault driver has no insurance.

California has some of the highest rates of uninsured drivers in the country. According to data tracked by the American Bar Association, uninsured motorist issues rank among the most common complications in California personal injury claims. Having UM/UIM coverage on your personal policy before you ever get in a rental car is worth checking.

Step Seven: Talk to a Car Rental Accident Attorney Before Accepting Any Settlement

Rental companies and their insurers move fast. They may contact you within days offering a settlement that sounds reasonable. It almost never is. Once you sign a release, you give up the right to pursue additional compensation, even if your injuries turn out to be more serious than they appeared.

A Santa Ana car rental accident lawyer can review the offer, assess the full value of your claim — including medical bills, lost wages, and pain and suffering — and advise you on whether to accept or negotiate. This costs you nothing upfront. Most California personal injury attorneys work on contingency, meaning they only get paid if you recover money.

The same applies to vehicle damage disputes. Rental companies sometimes bill renters for “loss of use” — the revenue they supposedly lost while the car was being repaired. California courts have addressed this, and there are limits to what rental companies can legally recover. An attorney who handles these cases regularly will know exactly where those limits are.

Common Mistakes to Avoid

Posting about the accident on social media is one of the fastest ways to hurt your own case. Adjusters look at public posts. A photo of you smiling at dinner two days after a crash can be used to argue your injuries weren’t serious.

Signing anything from the rental company without reading it carefully is another frequent problem. Some forms are simple accident reports. Others contain language that releases the company from claims. If you’re unsure what you’re signing, don’t sign it until you’ve spoken to an attorney.

Assuming the rental company’s insurance covers you is also a mistake. The damage waiver protects you from vehicle damage claims by the rental company — it is not liability coverage for injuries to other people or passengers.
