High-Risk Roads & Intersections

Where Accidents Happen Most in San Dimas

These are the roads and intersections where Gonzales Law Offices most frequently handles accident cases for San Dimas clients. We know these roads — and how to build cases around them.

I-10 Freeway — San Dimas Corridor
The I-10 through San Dimas carries heavy east-west freight and commuter traffic. The San Dimas Ave and Lone Hill Ave interchanges generate frequent merging accidents and rear-end collisions.
HIGH RISK
I-210 Freeway — Northern San Dimas
The I-210 along San Dimas's northern edge sees commuter traffic from the SGV to the Inland Empire. Interchange ramps at Via Verde are high-risk zones.
HIGH RISK
San Dimas Ave — I-10 to Foothill Blvd
San Dimas Ave is the city's main north-south connector. Heavy traffic to Raging Waters and local commercial areas creates constant intersection conflicts.
HIGH RISK
Foothill Blvd (Route 66) — San Dimas Section
Historic Route 66 through San Dimas has heavy retail traffic and multiple signalized intersections. Pedestrian and bicycle conflicts are common near the Village District.
HIGH RISK
Lone Hill Ave — I-10 to Arrow Hwy
Lone Hill Ave serves as a major parallel route to San Dimas Ave. Industrial and commercial traffic on the south end creates dangerous speed differentials.
MODERATE RISK
Bonita Ave — San Dimas Ave to Via Verde
Bonita Ave serves residential and school areas. School zone accidents near Lone Hill Elementary and middle school increase accident frequency during school hours.

⚠ Evidence Is Disappearing Right Now

What Happens to Your Case If You Wait

Insurance companies are already building their defense. Every hour you delay, critical evidence vanishes — and your compensation shrinks. Here's the timeline that works against you.

Critical
24–48 HRS
Security Camera Footage Deleted
Traffic cameras, business cameras, and dashcam footage that could prove the other driver's fault are often overwritten within 48 hours. Once deleted, it's gone forever.
Urgent
3–7 DAYS
Insurance Adjuster Contacts You
The at-fault driver's insurer will call you within days to get a recorded statement. Anything you say can be used to reduce your payout. Do NOT speak to them without an attorney.
Danger
30 DAYS
Lowball Offer Expires
Insurers make early low offers with expiration pressure. They know unrepresented victims often accept. Once you accept, you waive all future rights — even if your injuries worsen.
Severe
90+ DAYS
Settlement Value Drops 67%
Studies show victims who wait 90+ days to hire an attorney recover significantly less. The longer you wait, the weaker your case becomes. Call today — it costs nothing.

Your Path to Compensation

How Your San Dimas Case Works

From the moment you call to the day you receive your check — 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 member of his team will assess your case within minutes, answer your questions honestly, and tell you exactly what your case may be worth. No pressure, no obligation, no cost.
2
Immediate Investigation
We act fast. Within 24–48 hours we dispatch investigators to the scene, request the police report, preserve security camera footage (which gets deleted fast), obtain the at-fault driver's insurance information, and document all evidence. Speed is critical.
3
Medical Care Coordination
We connect you with top orthopedic surgeons, neurologists, pain management specialists, and physical therapists in the Los Angeles County area — with zero upfront cost to you. Your treatment is documented precisely to maximize your claim value.
4
Aggressive Negotiation
We handle every communication with the insurance company. Mark Gonzales was a former insurance defense attorney — he knows every lowball tactic they use and how to counter them. We reject inadequate offers and demand full compensation.
5
Litigation If Necessary
If the insurer refuses to pay a fair amount, we file suit and take your case to trial. Unlike "settlement mills," we are fully prepared to litigate — and insurance companies pay more when they know we mean it. Most cases settle; we're ready when they don't.
6
You Get Paid — We Take Our Fee
When we win, you receive your settlement check. Our fee comes only from the recovery — typically 33–40% of the settlement. You never pay out of pocket for anything, ever. We advance all costs: investigation, experts, filing fees, medical records.

Your Attorney

Mark A. Gonzales, Esq.

Mark Gonzales (CA State Bar #249340) is the founding attorney of Gonzales Law Offices. He graduated from the University of La Verne College of Law and began his career as an insurance defense attorney — representing insurance companies and learning every tactic they use to deny and minimize claims.

In 2013, he switched sides — choosing to fight for injured victims instead of insurance companies. That insider knowledge has given Gonzales Law Offices an unfair advantage in negotiations and litigation. He knows exactly when an insurance company's "final offer" isn't actually final.

Mark is a member of the State Bar of California, Consumer Attorneys of California (CAOC), Consumer Attorneys of Los Angeles (CAALA), and the San Bernardino County Bar Association. He holds an Avvo Superb 10.0 rating and has been recognized as a Super Lawyers Rising Star.

He speaks Spanish fluently, personally handles all complex negotiations, and makes himself available to clients directly — not through intermediaries.
