While any type of car accident can be overwhelming, crashes involving 18-wheelers and other large commercial vehicles are especially so. These tend to be the most devastating collisions, often leading to extensive bodily injury, death, and massive property damage. What's more, these cases move fast. By the time you or a family member left the crash scene, the trucking company’s insurer had likely already made calls. Carriers involved in serious crashes routinely deploy their own adjusters and accident reconstruction teams within hours. Sometimes this happens before the injured driver has even been discharged from the emergency room.
In 2024, Bexar County recorded 2,684 commercial vehicle accidents, ranking it the third-highest county in Texas for commercial vehicle crashes. These incidents are not theoretical but real, everyday risks drivers face right here in San Antonio and the surrounding areas. The sheer volume of commercial vehicle crashes also means that the defense often operates on a well-worn playbook. It might be your first time ever being involved in such an accident, but it's probably not the trucking company or insurance provider's first time defending against this type of claim.
We built The Warrior Law to run a counter-playbook, and we move just as fast as any trucking company. In our first year alone, we recovered over $1 million in settlements and verdicts for our clients, and we're just getting started. We understand what these cases involve, and we are prepared to do what it takes to get our clients the accountability they deserve. We initiate investigations immediately, because we know building a truck accident case is a race against evidence that won't last forever, strict filing deadlines, and a defense team that already has a head start.
Here’s what we actually do when you call us, and why every hour and every day after the accident matters.
The Investigation Starts the Moment You Call Us
Most people assume a truck accident claim works roughly like a car accident claim. File with insurance, exchange information, wait for a settlement offer. But the reality is that these cases are much different and far more time-sensitive than a standard fender-bender.
The Electronic Data Window
The Electronic Control Module (ECM), sometimes called the truck’s black box, records vehicle speed, braking application, throttle position, and engine hours in the seconds before impact. Depending on the truck and carrier, that data can begin overwriting within 7 to 30 days of a crash. The Electronic Logging Device (ELD), which tracks a driver’s duty status and hours of service, is a separate system controlled by the carrier. Carriers who know litigation is coming have been known to manipulate or delete ELD records before any attorney gets access. A third system, the Event Data Recorder (EDR), captures crash-specific triggers and has its own retention variables.
The 90-Day Body Camera Window
Beyond the truck itself, San Antonio Police Department body camera footage operates under a 90-day rolling deletion window under Texas law. If we don’t submit a records request to SAPD well before that window closes, footage that could independently corroborate speed, road conditions, or driver behavior is gone. There’s no recovering it after it's been deleted.
How Texas House Bill 19 Shapes the Case
Texas House Bill 19 splits a trucking case into two phases if the carrier requests it. In Phase 1, the jury focuses on driver negligence and compensatory damages. Company-level conduct (hiring practices, training records, supervision history) is largely reserved for Phase 2, and only after driver fault has been established in Phase 1. In plain terms: we have to build a strong driver-negligence case first before we can bring the full weight of the carrier’s corporate conduct before a jury. Every day without a spoliation letter in place narrows what we can ultimately prove about the company behind the driver.
Step One: Locking Down the Evidence Before It Disappears
The first thing we send after taking a case is a spoliation letter. This is a formal legal demand that puts the trucking company on notice to preserve specific categories of evidence, such as ECM and EDR data, ELD records, driver logs, dispatch communications, dashcam footage, maintenance records, and any post-crash inspection reports. Once that letter is served, any intentional destruction of covered evidence can be used against the carrier at trial as evidence of consciousness of guilt.
Simultaneously, we file a records request to SAPD for officer body camera footage, in-car dash camera footage, and any crash reconstruction documentation the department compiled. That request goes out within days, not weeks, because the 90-day deletion window doesn’t pause for settlement negotiations.
Preservation demands don’t stop at the carrier. Depending on the facts of your crash, we send notices to the freight broker who arranged the load, the cargo loading company, any maintenance contractor who serviced the truck, and any third-party logistics provider in the chain. Each entity may hold separate records relevant to what failed and why.
Step Two: Pulling the Electronic Data to Tell an Objective Story
Once preservation is locked down, we move to extraction. ECM data is subpoenaed and analyzed by a qualified technician. What it shows is specific: the truck’s exact speed in the seconds before impact, when brakes were applied, how hard, and whether the driver took any evasive action. On a corridor like Loop 410 or IH-35, where posted limits and traffic conditions are well-documented, that speed data can directly establish whether the driver was operating negligently.
ELD records get cross-referenced against the driver’s paper logs. When a carrier has pressured a driver to meet an unrealistic delivery schedule, the ELD often tells a different story than the paper log. Falsified entries and hours-of-service violations, which are federally regulated under FMCSA rules, become direct evidence of fatigue-related negligence. A driver who’s been on the road beyond the federally regulated 14-hour duty limit isn’t a freak accident. That’s a foreseeable consequence of a carrier’s scheduling decisions.
GPS records and internal dispatch communications are subpoenaed separately. Text messages, routing instructions, and dispatcher notes can reveal whether the carrier knew the driver was behind schedule and pressuring them to meet unrealistic or unsafe deadlines. That communication thread is often what connects individual driver error to corporate decision-making.
Step Three: Identifying Every Party That Shares Liability
One of the most consequential differences between a car accident and a commercial truck crash is the number of parties who may share liability. The driver is rarely the only one responsible for a crash.
We investigate the full chain of liability from the start:
- The motor carrier bears primary responsibility for the driver’s conduct under the legal doctrine of respondeat superior, which means an employer is liable for an employee’s negligent acts performed within the scope of employment.
- The freight broker may share liability if they engaged a carrier with a documented unsafe record.
- The cargo loader can be liable if improper loading contributed to instability or cargo spillage.
- The maintenance contractor is relevant when brake failure, tire blowouts, or other mechanical defects played a role.
Each of these parties carries separate insurance coverage. Identifying the full scope of available insurance (which, for commercial carriers, can run from a $750,000 federal minimum up to $1 million, $5 million, or higher with umbrella layers) is part of the investigation itself, not an afterthought during settlement negotiations.
We also pull the carrier’s profile from the FMCSA SAFER system and review their Compliance, Safety, Accountability (CSA) scores. CSA scores rate carriers across categories including unsafe driving, hours-of-service compliance, and vehicle maintenance. A carrier with deteriorating scores across multiple categories didn’t just put one bad driver on the road. They demonstrated a pattern, and that pattern matters, both to how they approach settlement and to how a Bexar County jury would view them.
Step Four: Bringing in the Outside Professionals to Reconstruct What Happened
Electronic data tells us what the truck did. Outside professionals explain what it means and what it cost you.
Accident Reconstruction
Accident reconstruction professionals combine ECM output with physical evidence from the scene: skid marks, debris patterns, gouge marks in the pavement, and the roadway geometry of the specific intersection or highway segment where the crash occurred. They produce a model of the crash sequence, vehicle speeds, and angles of impact that can be explained to a jury in plain terms. On corridors like US-90 or US-281, where grade changes and interchange geometry vary, that reconstruction work is highly location-specific.
Medical Damages
Medical professionals and records can help connect your specific injuries to the mechanics and force of the crash. Emergency room bills aren’t the whole cost; they’re merely a starting point. The full picture includes future surgeries, long-term rehabilitation, assistive equipment, home modification costs, and ongoing pain management. A medical professional who can trace those needs directly to the crash is what converts an injury into a compensable harm with an actual, provable number attached.
Lost Earning Capacity
When injuries affect your ability to work, we bring in economists and life care planners to project lost earning capacity over a realistic working life. Those projections, supported by methodology a Bexar County jury can follow, are what make the difference between an insurance company’s opening offer and a number that actually reflects what happened to you.
What Makes a Truck Crash Legally Different From a Car Accident
State negligence law applies to both types of accidents, but a commercial truck crash layers federal FMCSA regulations on top of Texas law in ways that create obligations and violations that don’t exist in an ordinary collision.
Federal Regulations That Apply to Commercial Carriers
Hours-of-service rules under federal law limit how long a commercial driver can operate before taking mandatory rest periods. Cargo securement standards under 49 CFR Part 393 govern how loads must be fastened and distributed. Vehicle maintenance obligations under 49 CFR Part 396 require carriers to inspect, repair, and maintain trucks on a defined schedule. Driver Qualification Files must document licensing, medical certifications, road test results, and employment history for every driver a carrier puts behind the wheel.
A violation of any of these federal standards isn’t just a regulatory infraction. It’s evidence of negligence per se under Texas law, meaning the violation itself can establish the breach of duty element without additional argument.
How Texas House Bill 19 Affects Trial Strategy
Because HB 19 allows a defendant carrier to request a bifurcated trial, the early investigation phase isn’t just about evidence preservation. It’s about building the Phase 1 foundation that unlocks the deeper corporate liability case in Phase 2. That’s why the spoliation letter goes out immediately and why we begin constructing the driver-negligence case before anything else.
Local Defense Bar Experience
Bexar County’s volume of commercial vehicle litigation means the defense bar is experienced and prepared. Carriers and their insurers know local courts, local juries, and local judges. That familiarity cuts in both directions: we know how these cases are litigated here, too, and we conduct our investigation, gather evidence, and build a case with the Bexar County courthouse in mind.
The Evidence Window Is Measured in Days, Not Months
Under Texas Civil Practice and Remedies Code Section 16.003, personal injury plaintiffs have two years from the date of the incident to file a lawsuit. That deadline can create a false sense of time. The evidence that builds a strong case doesn’t wait two years. ECM data overwrites. SAPD body camera footage deletes at 90 days. Witnesses move or forget. Skid marks fade. The carrier’s investigators are already working to build a case against you.
What we offer that a large, bureaucratic law office often can’t is immediate access. Luis Guerrero’s personal cell number goes directly to clients, and our team answers calls on weekends. If you were in a crash on a Saturday night on IH-10, you don’t have to wait until Monday morning for a receptionist to return your call. Evidence preservation can begin within hours, not days after intake forms clear a queue.
