Car Accidents in Ontario — By the Numbers

Ontario's position as a major freight, logistics, and aviation hub means its freeways carry among the highest commercial vehicle volumes in California — creating elevated risk of serious accidents at all hours.

High-Risk Roads & Intersections

Where Accidents Happen Most in Ontario

These are the roads and intersections where Gonzales Law Offices most frequently handles accident cases for Ontario clients.

I-10 / I-15 Interchange — Ontario "Crossroads"
The I-10/I-15 interchange in Ontario is the critical junction between east-west and north-south freight movement across Southern California. It carries some of the highest combined commercial truck volumes in the state. High-speed merging, frequent lane changes, and oversized loads create constant accident risk. Our office handles multiple cases from this interchange every month.
CRITICAL RISK
Holt Blvd — Full Corridor (Euclid Ave to Vineyard Ave)
Holt Blvd is Ontario's most dangerous surface street — a long east-west arterial running through dense commercial, industrial, and residential areas. Its mix of retail driveways, bus stops, pedestrian crossings, and heavy through traffic makes it a constant accident zone. The intersections at Holt/Euclid, Holt/Grove, Holt/Vineyard, and Holt/Haven are among the most frequently cited accident locations in the city.
HIGH RISK
SR-60 (Pomona Freeway) — Ontario Segment
The SR-60 through Ontario connects to the I-15 and handles high volumes of commuter and commercial traffic from the San Gabriel Valley. The I-15/SR-60 interchange and the Milliken Ave / SR-60 interchange are frequent accident zones. Merge conflicts and high-speed rear-end collisions are the primary accident types.
HIGH RISK
Euclid Ave — I-10 to 4th St
Euclid Ave is one of Ontario's primary north-south arterials. The section between the I-10 and 4th St sees high commercial traffic volumes alongside residential cross-streets. The Euclid/Holt intersection has a documented history of serious T-bone collisions. Bicycle accidents on Euclid Ave are also increasingly common.
HIGH RISK
Vineyard Ave — Airport Access Road
Vineyard Ave serves as the primary ground transportation corridor for Ontario International Airport. Rental car shuttle traffic, rideshare vehicles, taxis, and commercial vans converge here creating constant conflict. Distracted driving near terminal drop-off zones generates frequent fender-benders and more serious accidents near the I-10 interchange.
HIGH RISK
Grove Ave — I-10 to 4th St
Grove Ave runs parallel to Euclid and handles significant overflow traffic including major commercial vehicles serving the warehousing and industrial zones east of the I-15. The Grove/Holt intersection and the Grove/I-10 on-ramp area are frequent accident locations.
MODERATE RISK
Ontario Mills Drive / I-10 Access
Ontario Mills is the largest outlet mall in the western United States. Weekend and holiday traffic creates severe congestion on the I-10 on/off-ramps at Milliken Ave and Mountain Ave. Distracted driving, sudden stops, and pedestrian conflicts in the massive parking complex generate consistent accident activity.
MODERATE RISK
4th Street — Euclid to Haven
4th Street is a primary east-west arterial through northern Ontario. Its intersection with Euclid Ave and the approach to the I-15 on-ramps sees significant accident activity. Proximity to schools in the area creates pedestrian hazard zones during school hours.
MODERATE RISK

Your Path to Compensation

How Your Ontario Case Works

From the moment you call to the day you receive your settlement — here's exactly what Gonzales Law Offices does for you.

1
Free 24/7 Case Evaluation
Call or text any time — day or night. Mark Gonzales or a senior team member will assess your case within minutes, answer every question honestly, and tell you what your case may be worth. No pressure, no obligation, zero cost.
2
Rapid Scene Investigation
We act immediately. Within 24–48 hours we dispatch investigators, secure police reports, preserve security camera footage before it's deleted, identify all involved insurance policies, and document the full evidence picture. In Ontario's busy freeway corridors, speed is critical.
3
Medical Care Coordination
We connect you with specialists throughout the Inland Empire — orthopedic surgeons, neurologists, pain management, physical therapy — at zero upfront cost. We work with Ontario Regional Medical Center, San Antonio Regional, and specialist networks who understand medical documentation for litigation.
4
Aggressive Multi-Party Negotiation
Ontario cases often involve multiple insurance policies — commercial trucking fleets, rideshare companies, corporate logistics carriers, Metrolink. Mark Gonzales has experience navigating every one of these policy structures and won't stop until every available source of compensation is exhausted.
5
Litigation If Necessary
If insurers refuse to pay fair value, we file suit and take your case to San Bernardino County Superior Court. We're fully trial-ready — and commercial insurers pay significantly more when they know Gonzales Law Offices will go to court. We never push you to accept less than you deserve.
6
You Get Paid — We Take Our Fee
When we win, your settlement check is issued. Our contingency fee comes only from your recovery. You never pay out of pocket — we advance all costs including investigators, expert witnesses, court filing fees, and medical record retrieval.

Ontario Areas We Serve

We know every area of Ontario — and the specific accident patterns in each neighborhood.

Airport / Vineyard Ave District
Ontario International Airport generates massive vehicle traffic on Vineyard Ave and the connecting I-10 ramps. Rental car shuttles, rideshare vehicles, and airport employees create complex multi-party accident scenarios. Our office handles airport-area accidents regularly.
HIGH ACCIDENT RATE
I-10 / I-15 Interchange Zone
The interchange area — including the approach corridors on Euclid Ave, Grove Ave, and Holt Blvd — generates the highest commercial truck accident concentration in Ontario. Injuries in this zone tend to be severe due to freeway speeds.
CRITICAL ACCIDENT RATE
Ontario Mills / SR-60 Corridor
Ontario Mills attracts massive weekend traffic that backs onto the SR-60 and I-10. Rear-end collisions on freeway on/off-ramps and in the mall access roads are frequent. The Milliken Ave SR-60 interchange is a consistent accident hotspot.
HIGH ACCIDENT RATE
Holt Blvd Corridor
The full length of Holt Blvd from Euclid to Vineyard is Ontario's highest-volume surface street corridor. Commercial and residential traffic mixing at dozens of signalized intersections creates constant T-bone and rear-end accident conditions.
HIGH ACCIDENT RATE
North Ontario / 4th Street
Residential neighborhoods north of Holt Blvd. Schools along 4th Street create pedestrian hazard zones during school hours. The approach to the I-15 at 4th Street generates moderate freeway-related accident activity.
MODERATE RISK
East Ontario / Jurupa Border
Industrial zone bordering Jurupa Valley. Warehouse and distribution truck traffic is extremely heavy, especially on night shifts. Lower residential population means accidents here are often solo vehicle or truck-related.
MODERATE RISK

Frequently Asked Questions

Ontario Car Accident — Common Questions

At Gonzales Law Offices there is absolutely zero cost unless we win your case. We work on a contingency fee — we take a percentage of your settlement only after you receive payment. No hourly fees, no upfront charges, no cost if we lose. Your free consultation is available 24/7 at 1-888-232-2898.
Step 1: Call 911 — get police and medical on scene.
Step 2: Get the other driver's insurance, license plate, and contact info.
Step 3: Photograph everything — damage, injuries, skid marks, intersection signs.
Step 4: Get contact info from witnesses at the scene.
Step 5: Seek medical care immediately — even if you feel fine (many injuries appear days later).
Step 6: Do NOT give a recorded statement to any insurance company without an attorney.
Step 7: Call Gonzales Law at 1-888-232-2898 before accepting any settlement offer.
Call Gonzales Law Offices immediately at 1-888-232-2898. Trucking companies dispatch their own investigators and legal teams within hours of an accident — you need an attorney on your side just as fast. Commercial truck cases involve federal regulations (FMCSA), multiple insurance policies, and corporate legal teams. Mark Gonzales has specific experience with Ontario's high-volume truck corridors and has recovered over $1M in multiple Ontario truck accident cases.
Airport accidents can be more complex depending on the vehicles involved. Rental cars involve corporate rental company insurance chains. Rideshare vehicles have multi-tier insurance structures depending on whether the driver was on-app or not. Commercial airport shuttle vans carry different insurance. Gonzales Law Offices handles all of these regularly and knows exactly which policies to pursue for maximum recovery.
California's statute of limitations is 2 years from the accident date. If a government vehicle was involved (Omnitrans bus, city vehicle, Metrolink), you have only 6 months to file a government tort claim. Camera footage and witness memories fade quickly — don't wait. Call us now for a free evaluation.
Case values depend on injury severity, medical costs, lost wages, and fault. Ontario's high rate of commercial truck accidents means case values are often significantly higher than typical car accidents — trucking companies carry multi-million dollar policies. Call 1-888-232-2898 for a free case evaluation. We'll give you an honest assessment within minutes.
Uninsured drivers are common in the Inland Empire. If you were hit by an uninsured or underinsured driver, you may recover through your own Uninsured Motorist (UM) coverage. California requires UM coverage unless specifically waived. Gonzales Law Offices has recovered hundreds of thousands of dollars for clients in uninsured driver situations — don't assume you have no options.
Yes. California uses pure comparative negligence — even if you were partially at fault, you can recover damages reduced by your fault percentage. Insurance companies routinely exaggerate claimant fault to reduce payouts. Gonzales Law Offices will fight back to ensure your fault is accurately assessed and your recovery is maximized.
