Truck Driver Fatigue Accidents in San Antonio — When Exhausted Drivers Put Everyone at Risk

A truck driver who has been behind the wheel for too many hours is a rolling hazard to every other vehicle on the road, and San Antonio’s position as a major freight corridor means that fatigued commercial drivers pass through Bexar County in staggering numbers every day. Driver fatigue slows reaction time, impairs judgment, and can cause a trucker to fall asleep at the wheel of an 80,000-pound vehicle traveling at highway speeds. The results are predictable and devastating. If you or someone in your family has been harmed in a truck accident caused by an exhausted driver, you deserve a San Antonio personal injury attorney who knows how to prove fatigue-related negligence and hold both the driver and the trucking company responsible. The truck accident lawyers at J.A. Davis & Associates have spent over 25 years handling complex commercial vehicle crash cases throughout South Texas.

Bexar County recorded 2,684 commercial motor vehicle crashes in 2024 according to the Texas Department of Transportation, with 18 people killed and hundreds more seriously injured. While TxDOT’s data does not break out fatigue as a specific cause, federal safety research consistently identifies driver fatigue as a contributing factor in a significant percentage of fatal truck accidents nationwide. The Federal Motor Carrier Safety Administration has estimated that drowsy driving plays a role in roughly 13 percent of commercial vehicle crashes resulting in serious injuries or fatalities. Applied to Bexar County’s numbers, that would suggest that well over 300 of last year’s truck accidents in San Antonio may have involved a fatigued driver.

The problem of driver fatigue in truck accidents across the San Antonio area is not simply a matter of individual irresponsibility. It is a systemic issue driven by an industry that pays drivers by the mile, imposes unrealistic delivery deadlines, and creates financial incentives for drivers to push past their physical limits. Trucking companies that pressure their drivers to deliver loads on schedules that cannot be met without violating hours-of-service regulations bear direct responsibility for the crashes that result. The truck accident attorneys at J.A. Davis & Associates go beyond the individual driver to pursue the corporate negligence that enables fatigue-related crashes.

Federal Hours-of-Service Rules and Why Trucking Companies Violate Them

The Federal Motor Carrier Safety Regulations establish specific limits on how long commercial truck drivers can operate before they must rest. Under current rules, a property-carrying driver may drive a maximum of 11 hours after 10 consecutive hours off duty, must not drive beyond the 14th hour after coming on duty, and must take a 30-minute break after 8 cumulative hours of driving. A 60/70-hour limit caps total on-duty time over 7 or 8 consecutive days. These rules exist because decades of safety research have proven that driver performance deteriorates significantly when these limits are exceeded.

Despite the clear evidence behind these regulations, violations remain widespread. Trucking companies manipulate schedules to squeeze more driving hours out of their operators. Some drivers maintain dual logbooks or tamper with electronic logging devices to conceal hours-of-service violations. The economic pressure to keep trucks moving is enormous, and the penalties for violations are often seen as a cost of doing business rather than a meaningful deterrent.

How to Prove Fatigue in a San Antonio Truck Accident Case

Proving that driver fatigue caused or contributed to a truck accident requires a thorough investigation of the driver’s records, the truck’s electronic data, and the circumstances of the crash. Electronic logging devices record the driver’s duty status in real time and can reveal whether the driver was in compliance with hours-of-service limits at the time of the collision. Event data recorders capture speed, braking, and steering inputs in the seconds before impact. GPS data shows the truck’s route, stops, and timing. Cell phone records may reveal whether the driver was awake and making calls during required rest periods. Dispatch records can show whether the company was pressuring the driver to meet a delivery window that would have required violating driving limits.

The Science of Fatigue and Driving Impairment

Research from the National Highway Traffic Safety Administration and the FMCSA has established that the cognitive impairment caused by fatigue is comparable to the impairment caused by alcohol. A driver who has been awake for 18 consecutive hours performs at a level similar to a driver with a blood alcohol concentration of 0.05 percent. At 24 hours without sleep, the impairment is equivalent to a BAC of 0.10 percent, which is above the legal limit for passenger vehicle drivers and well above the 0.04 percent limit for commercial vehicle operators. A fatigued truck driver who crashes into a family on I-35 or I-10 may be just as impaired as a drunk driver.

Trucking Company Liability for Fatigue-Related Crashes

When a trucking company creates conditions that make fatigue-related crashes foreseeable, that company shares liability for the resulting injuries and deaths. Evidence of corporate negligence in fatigue cases can include unreasonable delivery schedules, failure to monitor driver compliance with hours-of-service rules, pressure on drivers to falsify logs, inadequate rest facilities, and a pattern of hours-of-service violations in the company’s safety record. The FMCSA maintains a Safety Measurement System that tracks carrier compliance data, including hours-of-service violations, and this information can be invaluable in establishing a pattern of negligence.
