Ontario Personal Injury Attorney

Ontario is one of the busiest cities in San Bernardino County. Home to Ontario International Airport, the Ontario Mills shopping center, and one of the largest concentrations of warehouse and logistics operations in Southern California, the city sees an extraordinary volume of vehicle traffic, commercial truck activity, and pedestrian movement every day. With that activity comes serious risk — and a steady stream of personal injury claims involving residents, commuters, and visitors.

The Law Offices of Justin H. King represents personal injury victims throughout Ontario and the surrounding Inland Empire. The firm’s Rancho Cucamonga office is approximately 10 minutes from downtown Ontario, and Ontario civil cases fall within the same San Bernardino County Superior Court district where the firm files routinely. Attorneys Justin H. King, Jonathan L. King, and Oliver King — all recognized by Best Lawyers in America® — handle car accidents, truck accidents, motorcycle accidents, pedestrian injuries, slip and fall cases, dog bites, and wrongful death claims for Ontario residents.

Why Ontario Sees a High Volume of Personal Injury Claims

Ontario’s location at the intersection of Interstate 10 (the San Bernardino Freeway) and Interstate 15 (the Ontario Freeway) makes it one of the most heavily trafficked corridors in the Inland Empire. The four-level interchange where these two freeways meet — along the Ontario–Fontana city limit — carries an enormous volume of passenger vehicles and commercial trucks every day, and serious collisions are a regular occurrence.

Beyond the freeways, Ontario hosts a dense network of arterial roads serving the city’s logistics and retail economy. Holt Boulevard, Mission Boulevard, Euclid Avenue, Archibald Avenue, and Vineyard Avenue carry heavy local traffic, and Ontario Mills Parkway sees concentrated retail traffic during shopping seasons. The presence of Ontario International Airport adds rideshare and shuttle activity, while the warehouse district along the Ontario–Mira Loma corridor produces constant commercial truck movement to and from major distribution centers.

Common case types the firm handles for Ontario clients include:

Freeway collisions on the I-10 and I-15 — high-speed crashes, multi-vehicle pileups, and rear-end collisions in stop-and-go traffic
Commercial truck and big-rig accidents — particularly along the warehouse corridors and freeway on-ramps that serve Ontario’s logistics economy
Intersection collisions on heavily trafficked arterials like Holt Boulevard, Euclid Avenue, and Mission Boulevard
Pedestrian and bicycle injuries in retail areas around Ontario Mills and along Euclid Avenue
Rideshare and airport shuttle accidents involving travelers heading to or from Ontario International Airport
Slip and fall cases at retail centers, restaurants, and commercial properties
Dog bite and animal attack claims in residential neighborhoods
Wrongful death in catastrophic crashes and other fatal incidents

Where Ontario Personal Injury Cases Are Filed

Ontario civil cases — including most personal injury matters — fall within the Rancho Cucamonga District of the San Bernardino County Superior Court. Civil filings for Ontario, Rancho Cucamonga, Upland, Montclair, Chino, Chino Hills, and Alta Loma are all routed through the Rancho Cucamonga Courthouse at 8303 Haven Avenue. Larger or more complex civil matters may be filed at the San Bernardino Justice Center at 247 West Third Street in downtown San Bernardino.

Knowing the local court is more than a procedural detail. Filing rules, judicial assignments, and trial readiness procedures vary by district, and Ontario residents benefit from working with attorneys who appear regularly in the courthouses where their cases will actually be heard. The Law Offices of Justin H. King files civil matters in San Bernardino County Superior Court on a routine basis and is familiar with the judges, clerks, and procedures of both the Rancho Cucamonga and San Bernardino Justice Center civil divisions.

What to Do After an Accident in Ontario

The decisions made in the first hours and days after an accident often determine the strength of a personal injury claim. Anyone injured in Ontario should prioritize the following steps:

Get medical attention immediately. Even injuries that feel minor — soft-tissue damage, concussion symptoms, internal trauma — can worsen significantly over days or weeks. Emergency care is available at facilities including Kaiser Permanente Ontario Medical Center on East Riverside Drive and Montclair Hospital Medical Center just west of Ontario. Documenting injuries through medical records establishes the connection between the accident and the harm suffered.
Report the accident. For traffic collisions, this means calling 911 or the Ontario Police Department to ensure an official report is created. For workplace incidents, premises injuries, or dog bites, report to the property owner, employer, or animal control as appropriate.
Document the scene. Photographs of vehicle damage, the accident location, visible injuries, and any contributing conditions (debris, weather, signage) become important evidence. Capture witness names and contact information whenever possible.
Do not give a recorded statement to the other party’s insurance company. Insurance adjusters often contact accident victims early — before injuries are fully understood — to elicit statements that limit the value of a future claim. Statements should be made through legal counsel.
Consult a personal injury attorney before signing anything. Settlement offers, medical authorizations, and waivers from an insurance company should be reviewed by an attorney before being signed. The Law Offices of Justin H. King offers free consultations and operates on a contingency fee basis, meaning no attorney’s fees are owed unless a recovery is obtained.

Frequently Asked Questions About Ontario Personal Injury Claims

How long do I have to file a personal injury claim in Ontario, California?

California’s standard statute of limitations for personal injury claims is two years from the date of the accident. If the claim is against a government entity (city, county, state, or any government employee acting in their official capacity), a formal government claim must typically be filed within six months. Missing these deadlines generally bars the claim entirely, which is why early consultation with an attorney is important.

What does it cost to hire The Law Offices of Justin H. King?

Nothing upfront. The firm handles personal injury cases on a contingency fee basis — clients pay no attorney’s fees unless and until a recovery is obtained. The initial consultation is free.

What if the insurance company has already contacted me?

Insurance adjusters often reach out to accident victims within days of a crash, sometimes before injuries are fully understood. Anything said during these calls — including casual statements about how you are feeling — can be used to reduce the value of the claim. Decline to give a recorded statement until you have spoken with an attorney.

Will my Ontario case be filed in Ontario?

Civil personal injury cases involving Ontario incidents are typically filed in the San Bernardino County Superior Court Rancho Cucamonga District at 8303 Haven Avenue in Rancho Cucamonga, which has jurisdiction over Ontario civil matters. Larger or more complex matters may be filed at the San Bernardino Justice Center at 247 West Third Street in downtown San Bernardino.

What types of compensation can I recover after an Ontario accident?

California law allows recovery of medical expenses (past and future), lost wages and lost earning capacity, pain and suffering, property damage, and in cases of egregious conduct, punitive damages. Wrongful death cases additionally allow recovery for loss of companionship, financial support, and funeral expenses.

Do you handle cases involving Ontario International Airport?

Yes. Cases involving rideshare drivers, airport shuttles, taxi services, and rental car return areas at or near Ontario International Airport can present unique liability and insurance coverage questions. The firm has experience navigating these issues for Ontario travelers and airport personnel.

I was in a car accident on the 15 freeway near Rancho Cucamonga and had no idea where to turn. A family member referred me to The Law Offices of Justin H. King and it was the best decision I made. Justin handled everything personally from insurance calls, medical liens, all of it. He never made me feel like just another case. We settled for far more than I expected. If you're in the Inland Empire and need someone who actually knows how to fight for you, this is the firm.

After my car accident on the I-15 in Fontana, I was dealing with injuries, a totaled car, and an insurance company that kept stalling. The Law Offices of Justin H. King took my case and immediately made me feel like I had real advocates on my side. Jonathan King was incredibly thorough and kept me updated throughout the whole process. We ended up with a much better outcome than I thought possible. If you need a car accident lawyer in Fontana, don't wait. Call them first.

There’s so many things I can say about Justin, Garrett and the team. Of course having to get an attorney is stressful enough as it is.
When I called, I was welcomed with the utmost kindness! They listened to my story and never once made me feel unheard of unimportant! Justin, himself, responded so quickly to every call, text or concern. And Garrett, omg, very thorough, very sweet, very funny. The fact that I can relax and laugh was a great sign that I was in the right place. I’m grateful for the fight that they fought for me!
Hopefully I won’t be back, but if I need ANYTHING, I know they’re just a call/text away.
Thank you so incredibly much for literally everything!

I can’t say enough good things about Justin King Law. My attorneys, Oliver and Garrett, took incredible care of me and handled my case with empathy and professionalism. After being rear-ended, I was unable to pick up my children, and the situation felt overwhelming. They not only connected me with the right health professionals and care, but when the other insurance provider denied my claim, they fought hard—and secured even more than we originally asked for.

Garrett especially took the time to thoroughly explain the process to both me and my husband, making sure we always felt informed and confident. Thanks to them, I never had to worry. I was able to focus on my family and career while they handled everything. Within just six months, my case was closed, and Oliver personally greeted me in the office to walk me through the settlement.

I am truly grateful for their dedication and would recommend Justin King Law, a small family owned practice.

I hired J King Law to represent me when I was hit by a car walking into a grocery store in Hesperia, Ca. When I explained the situation to Justin and his firm they were extremely understanding and reassuring that this will be taken care of and they will fight for me. Throughout the process the whole team was very attentive and honest about everything that came up. I have nothing but, great things to say about this law firm. I highly recommend them to anyone that has suffered any injury whether it’s major or minor. The thing I appreciated most were the updates given almost every 2 weeks. They broke everything down to help me understand it all and I’m just so grateful for them. Thank you so much J King Law!

Wow! I can't say enough good things about the Law Offices of Justin King. Attitude starts at the top, & this firm is top tier. They represented me (& yes we won!) for an injury I sustained while riding my motorcycle westbound on the 10. Someone changed lanes without looking, which resulted in a knee injury, a lot of physical therapy, & a totaled motorcycle. I wasn't sure what to do or if this were even something worth pursuing. I found Justin's webpage & sent a quick message to him on a Saturday night then thought nothing of it. My first call from Justin was Sunday morning. I was immediately impressed. After hearing a bit of my story & asking a few questions I was ready to have Justin represent me. My first question was "How much do I need to come up with to get this started? Justin replied, you don't owe anything until we win. Not unless, until. That set the tone of the next 2 years of my life. As your case progresses it'll require work from you & a whole team working to represent you. Staci will call & let you know she's emailing documents that require signatures; Garrett will call to ask for details they need to understand & yes, he will call to remind you that you forgot to sign a document 3 days earlier. These are great people who genuinely care. They will take time to understand your needs & they communicate every step of the way. If you are injured, you need to call Justin & his team right away. You will not be disappointed!

Google only allows 5 stars, but these guys deserve 10!

I was involved in my first big automobile accident last year, in Yorba Linda. I was a bit overwhelmed as you can imagine. Friends suggested that I hire an attorney to handle my case and I was not quite sure how to proceed. I was very fortunate when I was referred to Justin King’s office.

I met with Mr. King and found him to be very personable and he listened to my concerns. I felt very comfortable and confident that he would help me in getting a fair outcome to my case.

I want to also thank Garrett Tuckerman for all he did in keeping me updated with everything going on with my case and for being there whenever I had any questions or concerns. I also want to mention Leoni Barrera who was always pleasant and supportive when I called.

I highly recommend The Law Offices of Justin H. King for your personal injury needs. I feel that Mr. King and his whole staff, with their knowledge, expertise and professionalism will help make your experience a less stressful one.

Last July I was struck by a falling case of liquor at Total Wine in Rancho Cucamonga which led to a slip and fall. My friends and family urged me to contact a lawyer after discovering I needed surgery to repair my broken wrist. A friend found Justin King on Google. Justin was compassionate, accessible, and took charge from the very first meeting. He was able to obtain the surveillance video capturing the entire incident, and made an appointment for me to see a prominent neurologist after the video showed the case struck the front of my head. The entire staff at The Law Offices of Justin H. King were very easy to work with, and I always felt like my case was getting personal attention. Thank you Garrett, Staci, and Leoni! My case went to mediation and settled for more than 3x what they originally offered. If you have been injured in an accident, I highly recommend The Law Offices of Justin H. King.

I want to thank Justin and his amazing office. They made a very traumatic/ nightmare of a situation into a more bearable situation every step of the way. They kept us updated and we were reassured that we were in good hands. I want to also express my gratitude to Garrett for being so empathic and supportive through the ups and downs that comes with a case. We are so blessed to have had them handle our case. I would recommend them to anyone who is looking for a professional and dependable office. Thank you again Justin King Office!!!

I went from feeling like a basket case from all the stress to feeling calm and collected after talking to Justin.

After an auto accident, I felt really nervous calling an attorney because I had never worked with one before. But from the first conversation I had with Jessica, I felt so at ease. Justin then called me and was so easy going and we had a nice conversation too. The entire staff took great care of me and I am very happy.

I was in a car accident that was not my fault two years ago. A friend of mine had a family member who had been helped in the past by Justin King, and they suggested I call him. I'm so glad I did! Justin and his team took great care of my situation and got a great settlement for me. I highly recommend them if you have been in an accident. You will be very happy with what this firm.

When I needed a lawyer following a car accident on the Interstate 15 Freeway in Rancho Cucamonga, Justin King, and his team were there for me. I appreciated how his entire staff always seemed happy to answer my questions and were so good about returning all my phone calls and emails. I could tell this firm has immense experience in helping people get their life back after an unfortunate car crash. I was so happy with the outcome of my case and the results Justin obtained from the insurance company on my behalf. I have recommended their office to all my family members and neighbors. I hope you never need to call them. But if you need the best car accident lawyers, I can vouch that they are excellent.
