Motor Vehicle Accident Lawyers in Dallas — Attorney911 Fights for You
One moment, you were driving on Dallas’s roads. The next, an 80,000-pound truck jackknifed across I-35E, or a distracted rideshare driver ran a red light on the Stemmons Freeway, or a fatigued oilfield water hauler lost control on FM 157 near your neighborhood. In an instant, your life changed. The pain is constant. The medical bills are mounting. The insurance adjuster is calling — sounding helpful, but you know they’re not on your side.
You’re not alone. Dallas has 46,257 crashes every year — one every 11 minutes. In 2024 alone, 331 people died on Dallas County roads, and 10,586 were seriously injured. On I-35E near the Dallas North Tollway, where commuter traffic mixes with freight trucks, rear-end collisions and sideswipes are daily events. On the Stemmons Freeway, where rideshare drivers weave between lanes to meet delivery quotas, T-bone crashes at intersections like Harry Hines and Mockingbird are tragically common. On FM 157 in Mansfield and Midlothian, oilfield trucks hauling produced water and frac sand share narrow two-lane roads with families heading to school and soccer practice — creating a perfect storm for catastrophic rollovers and head-on collisions.
The trucking company has a team of lawyers. The rideshare platform has a rapid-response team. The oil company has investigators on-site before the ambulance leaves. They’re working to protect their interests — not yours.
You need someone who knows their playbook. Someone who’s been on their side. Someone who fights for Dallas families.
That’s Attorney911.
Why Dallas Families Trust Attorney911 After a Crash
Ralph Manginello — 27+ Years Fighting for Texas Families
Ralph Manginello didn’t just become one of Dallas’s most trusted accident attorneys — he was born to fight for justice. Raised in Houston’s Memorial area, Ralph grew up understanding Texas values: hard work, fairness, and standing up for what’s right. After earning his law degree from South Texas College of Law Houston and being admitted to the Texas Bar in 1998, Ralph has spent his entire career holding negligent parties accountable.
Ralph’s credentials speak for themselves:
- Federal court admission to the U.S. District Court, Southern District of Texas — essential for handling complex trucking, maritime, and corporate cases that often cross state lines
- 27+ years of trial experience — insurance companies know which attorneys are willing to go to court, and Ralph’s track record proves he’s not bluffing
- BP Texas City Refinery explosion litigation — Ralph was part of the legal team that secured justice for the 15 workers killed and 170+ injured in one of the worst industrial disasters in U.S. history, demonstrating his ability to take on billion-dollar corporations
- $10 million University of Houston hazing lawsuit — Ralph is currently fighting to hold institutions accountable, showing his commitment to justice extends beyond vehicle accidents
- Journalism degree from UT Austin — before arguing cases in court, Ralph learned how to tell stories that resonate with juries
- HCCLA membership — Ralph handles both criminal and civil cases, giving him unique insight into DWI accidents where criminal charges intersect with civil claims
Ralph’s son, RJ Manginello, is a collegiate basketball player at Montreat College, following in his father’s athletic footsteps after a standout high school career at Second Baptist School in Houston. This family connection gives Ralph a deep understanding of what it means to fight for the people you love — a perspective he brings to every case.
But here’s what clients say about Ralph:
“Mr. Manginello guided me through the whole process with great expertise…tenacious, accessible, and determined throughout the 19 months.” — Jamin Marroquin
“Ralph Manginello is indeed the best attorney I ever had…He cares greatly about his results.” — AMAZIAH A.T.
“Ralph is an AMAZING ATTORNEY. I have used him 2 TIMES FOR 2 separate cases…He gets the JOB DONE RIGHT!” — Cassie Wright
Lupe Peña — The Insurance Company Insider Who Switched Sides
Most law firms claim they know how insurance companies work. Attorney911 has something better: an attorney who used to work for them.
Lupe Peña spent years at a national defense firm, learning the exact tactics insurance companies use to minimize claims. He knows:
- How they value claims using Colossus software — and how to beat the algorithm
- Which “independent” medical exam doctors they hire to minimize injuries — because he hired them
- How they set reserves to lowball settlements — and how to increase them
- How they use recorded statements to twist your words — because he wrote the scripts
- How they exploit gaps in treatment to argue you weren’t really hurt — because he used this tactic for years
Now, Lupe uses that knowledge to fight FOR victims — not against them.
“Lupe’s insider knowledge from years at a national defense firm means we don’t just anticipate the insurance company’s strategies — we’ve deployed them ourselves.” — Attorney911
Lupe is also a third-generation Texan with deep roots in the King Ranch area, fluent in Spanish, and committed to serving Dallas’s diverse communities. He grew up in Sugar Land and now lives there with his family, giving him a personal connection to the roads and neighborhoods where Dallas families live, work, and face accidents every day.
Proven Results for Dallas Families
We don’t just talk about fighting for victims — we prove it with results. Here are some of the cases we’ve handled for Texas families:
Multi-Million Dollar Brain Injury Settlement
“Multi-million dollar settlement for client who suffered brain injury with vision loss when log dropped on him at logging company.”
Our client was working at a logging site when a log fell on him, causing a traumatic brain injury that left him with permanent vision loss. The logging company’s insurance tried to argue he was partially at fault for being in the wrong place. We investigated and proved the company failed to follow safety protocols. The case settled for multiple millions of dollars.
Amputation After Car Accident Complications
“In a recent case, our client’s leg was injured in a car accident. Staff infections during treatment led to a partial amputation. This case settled in the millions.”
Our client’s leg injury seemed manageable at first — until complications set in. During treatment, staff infections developed, and doctors had no choice but to perform a partial amputation. The insurance company offered $50,000, claiming the amputation was a “medical complication” not related to the accident. We brought in medical experts who proved the amputation was a direct result of the accident injuries. We documented lifetime prosthetic costs, lost earning capacity, and the profound impact on daily life. The case settled in the millions — not the $50,000 they initially offered.
Trucking Wrongful Death Cases
“At Attorney911, our personal injury attorneys have helped numerous injured individuals and families facing trucking-related wrongful death cases recover millions of dollars in compensation.”
When a loved one is killed in a trucking accident, no amount of money can bring them back. But holding the responsible parties accountable can provide financial security for the family left behind and send a message that negligence has consequences. We’ve recovered millions for families who lost spouses, parents, and children in trucking accidents across Texas.
Maritime Back Injury Settlement
“In a recent case, our client injured his back while lifting cargo on a ship. Our investigation revealed that he should have been assisted in this duty, and we were able to reach a significant cash settlement.”
Maritime work is dangerous, and employers have a legal duty to provide safe working conditions. When our client was injured lifting cargo on a ship, we proved the employer failed to follow safety protocols that required assistance for heavy lifts. The case settled for a significant amount, demonstrating our expertise in Jones Act and maritime injury claims.
DWI Dismissals — Proving We Fight on All Fronts
While we specialize in civil recovery for accident victims, Ralph’s membership in the Harris County Criminal Lawyers Association (HCCLA) means we also handle criminal defense — including DWI cases that often arise from the same accidents that cause civil claims. Here are three DWI cases we’ve successfully defended:
- “Our client was charged with drunk driving based on a breath test. Our investigation revealed that a police department employee was not properly maintaining the breathalyzer machines. The charges were dismissed.”
- “Our client drove home at 2:30 a.m., hit a curb and rolled his car, injuring a passenger. We learned that 1) police conducted no breath or blood test, 2) EMS didn’t note intoxication, 3) nurse notes from hospital were missing. Case dismissed on day of trial.”
- “Our client was charged with DUI/DWI, state’s primary evidence was video field sobriety test. We succeeded in having case dismissed because our client did not appear drunk in the video.”
These cases demonstrate our ability to handle both the criminal and civil sides of DWI accidents — a rare capability that gives our clients a significant advantage.

Dallas’s Most Dangerous Roads — Where Accidents Happen Every Day
Dallas’s roads are among the most dangerous in Texas. In 2024, Dallas County recorded 46,257 crashes — that’s one crash every 11 minutes. These crashes killed 331 people and seriously injured 6,069 others. But the danger isn’t evenly distributed. Some roads, intersections, and corridors see far more crashes than others.
I-35E — Dallas’s Deadliest Highway
I-35E is one of the most dangerous highways in Texas. This north-south corridor connects Dallas to Denton and carries a mix of commuter traffic, freight trucks, and oilfield vehicles. The stretch between the Dallas North Tollway and I-635 is particularly hazardous, with frequent rear-end collisions, sideswipes, and rollovers.
Why it’s dangerous:
- High truck traffic: I-35E is a major freight corridor, with 18-wheelers, tanker trucks, and oilfield vehicles sharing the road with commuters
- Congestion: Rush hour traffic creates stop
