When a commercial truck collides with a passenger vehicle on a West Texas highway, the results are often catastrophic. These massive vehicles weigh up to 80,000 pounds when fully loaded, and the impact of a crash at highway speed leaves victims with severe injuries, mounting medical bills, and an uncertain future. What many people do not realize is that a complex set of federal regulations governs how trucking companies and their drivers must operate, and violations of those rules can be the deciding factor in a personal injury claim.
If you have been injured in a truck accident, understanding the federal rules that apply to commercial carriers can be an important part of building your case. Attorney Chaile Allen has 15 years of experience representing injured West Texans across Taylor, Ector, Nolan, Scurry, and surrounding counties, and The Law Firm of Chaile Allen takes a hands-on, personalized approach to every truck accident case.
The Agency Behind the Rules
The Federal Motor Carrier Safety Administration (FMCSA) is the federal agency responsible for regulating the trucking industry across the United States. Its rules are binding on trucking companies, fleet owners, and individual commercial drivers alike. When any of these parties violates FMCSA regulations and causes an accident, that violation can serve as powerful evidence of negligence in a personal injury case.
Understanding which rules apply to your case starts with knowing what the FMCSA requires, because those requirements exist for one reason: to keep people like you safe on the road.
Hours of Service Limits

Driver fatigue is one of the leading contributors to serious truck accidents, and the FMCSA’s hours of service (HOS) regulations are designed to address it directly. According to the FMCSA’s summary of hours of service regulations, property-carrying commercial drivers are subject to strict limits on how long they may operate their vehicles.
The key rules include the following:
- Drivers may not operate a commercial vehicle for more than 11 hours after taking 10 consecutive hours off duty
- No driver may remain on duty beyond the 14th hour after coming on duty
- A mandatory 30-minute break is required after 8 cumulative hours of driving
- Drivers are capped at 60 hours of on-duty time over 7 consecutive days, or 70 hours over 8 consecutive days
These limits are strictly enforced through electronic logging devices (ELDs), which automatically record a driver’s hours. When a trucking company disables or manipulates an ELD, or when a driver falsifies logs, the violation can become critical evidence in your case.
Weight, Cargo, and Vehicle Maintenance Requirements
Federal regulations also govern how much weight a commercial truck may carry and how that cargo must be secured. Overloaded trucks are harder to stop, more prone to rollovers, and far more dangerous in the event of a collision. The maximum allowable gross vehicle weight for most commercial trucks on interstate highways is 80,000 pounds without a special permit.
Beyond weight limits, trucking companies are required to conduct regular inspections and maintain their vehicles in safe working condition. Brake failures, worn tires, defective lighting, and steering problems are all maintenance issues that federal rules require carriers to identify and correct. If a mechanical failure contributed to your personal injury, maintenance records obtained during the legal process could reveal a history of neglect.
Drug and Alcohol Testing Requirements
The FMCSA mandates drug and alcohol testing for all commercial motor vehicle drivers. Carriers must conduct pre-employment testing, random testing throughout the year, and post-accident testing following any crash that involves a fatality, injury, or disabling vehicle damage. The legal limit for blood alcohol concentration for a commercial driver is 0.04 percent, which is half the standard limit for non-commercial drivers in Texas.
If a driver was impaired at the time of your accident, post-accident testing records and prior testing history from the carrier may reveal a pattern of substance abuse. This kind of evidence can strengthen a negligence claim significantly and may even support a claim against the trucking company for retaining a driver with a known substance problem.
Electronic Logging Devices and Black Box Data
Modern commercial trucks are equipped with electronic systems that record far more than just driving hours. Event data recorders, sometimes called black boxes, capture vehicle speed, braking patterns, steering input, and other data in the moments before and during a crash. This information can be invaluable in reconstructing exactly what happened and establishing fault.
It is important to act quickly because trucking companies are not required to preserve this data indefinitely. An attorney can send a preservation demand shortly after an accident to prevent the destruction of critical records. If you were injured in a pedestrian accident or vehicle collision involving a commercial truck, preserving this data early can make a meaningful difference.
How Regulatory Violations Strengthen Your Claim
When a trucking company or driver violates FMCSA regulations, that violation does not automatically guarantee a legal outcome in your favor. However, it is powerful evidence. Violations of hours of service rules, maintenance requirements, or drug testing mandates can demonstrate a failure to uphold the standard of care owed to other people on the road.
Texas follows a modified comparative fault rule, which means you may still recover compensation even if you are found partially at fault for an accident, as long as your share of liability does not exceed 50%. Understanding how federal violations factor into liability is one reason why working with an experienced personal injury attorney matters so much after a serious truck crash.
