When a commercial truck crash happens on I-35E, I-635, or the Stemmons Corridor, the question of legal responsibility is not answered by Texas law alone. A dense framework of federal regulations governs nearly every aspect of commercial trucking in the United States — and when those rules are violated, those violations are often the sharpest tool available in a Dallas truck accident case.
The Federal Motor Carrier Safety Administration (FMCSA) is the primary federal agency responsible for regulating commercial vehicles and the companies that operate them. When a truck driver or trucking company violates a federal safety regulation, that violation can serve as evidence of negligence in a Texas civil lawsuit under the doctrine of negligence per se — meaning the violation itself demonstrates negligence without needing to separately establish what reasonable care would have required.
Right after a Dallas truck crash, do this
Get emergency medical care — call 911 even if you feel uninjured, and follow every treatment instruction your doctors give. Confirm an official crash report will be filed and ask for the report number. Photograph vehicle positions, skid marks, debris, cargo spillage, and any visible truck markings including the DOT number. Get witness names and contact information. Call a truck accident lawyer before speaking with the trucking company’s insurer — key electronic records like ELD data have short retention windows, and immediate legal action to preserve them can make the difference in your case.

Hours-of-service regulations
The FMCSA hours-of-service rules are among the most frequently violated federal trucking regulations and among the most consequential. For property-carrying commercial drivers: drivers may drive no more than 11 hours after 10 consecutive hours off duty; once on duty, they may not drive past the 14th consecutive hour; drivers who have driven 8 cumulative hours without a 30-minute break must stop; and drivers may not exceed 60 on-duty hours in 7 days (or 70 hours in 8 days).
Fatigued driving is one of the leading causes of catastrophic truck crashes. ELD data documenting an HOS violation in the hours before a Dallas crash is among the most powerful evidence available in any truck accident case.
Electronic logging device (ELD) requirements
Since December 2017, most commercial drivers have been required to use electronic logging devices instead of paper logbooks. ELDs automatically record driving time, engine status, vehicle movement, and location in a tamper-resistant format. In our Dallas truck accident investigations, ELD data is often the first evidence we act to preserve — it can document whether a driver exceeded their legal hours and whether there are discrepancies between dispatch logs and ELD records.
CDL requirements and driver qualification standards
Federal regulations establish who is legally permitted to operate a commercial motor vehicle: drivers must hold a valid CDL with appropriate endorsements; must pass a physical examination and maintain an active medical certificate; must undergo drug and alcohol testing; and carriers must verify a driver’s license history and prior safety record before hiring. When a trucking company hires a driver who lacks required qualifications, the company commits negligent hiring — an independent act of corporate negligence.
Vehicle inspection and maintenance requirements
Federal regulations require commercial trucks to be maintained in safe operating condition at all times. Drivers must systematically inspect vehicles before and after each trip; each vehicle must pass a comprehensive annual inspection; certain defects require the vehicle to be taken out of service immediately; and carriers must maintain inspection and repair records. When a crash is caused by a mechanical failure, the maintenance file is the first evidence we examine.
Cargo securement regulations
FMCSA cargo securement standards specify in detail how freight must be loaded, tied down, and transported. Overloaded trailers, improperly balanced cargo, and inadequately secured freight can cause tire failures, rollovers, and jackknife accidents. When cargo securement failures contribute to a crash, both the carrier and the loading company may face liability.
How Patterson Law Group investigates regulatory violations in Dallas cases
At Patterson Law Group, our investigation includes: immediate preservation demands for ELD records, driver logs, maintenance files, and driver qualification documents; review of the carrier’s FMCSA Safety Measurement System profile for patterns of prior violations; analysis of the driver’s qualification file; comparison of maintenance logs against required inspection schedules; and coordination with trucking industry experts. We handle truck accident cases across North Texas every week and understand how Dallas County juries receive regulatory evidence.
Frequently asked questions
Does a federal regulatory violation automatically mean the trucking company is liable? A violation is strong evidence of negligence, but you still need to demonstrate a causal connection — that the specific violation contributed to the crash and your injuries. Our job is to draw that connection clearly and persuasively.
Can I access a trucking company’s FMCSA safety record? Yes. The FMCSA’s Safety Measurement System is publicly accessible and tracks carriers’ inspection history, violation rates, and crash records. We review SMS data as a standard part of every Dallas truck accident investigation.
