What Causes Truck Accidents in San Antonio — The Factors Behind 2,684 Crashes in Bexar County

When a truck accident shatters your life, the first question that runs through your mind is why. Why did this happen? What went wrong? Who is responsible? Understanding the causes of commercial vehicle crashes is essential to holding negligent parties accountable and recovering the compensation you need to rebuild your life. In 2024, Bexar County experienced 2,684 commercial motor vehicle crashes that killed 18 people and injured hundreds more, and each of those crashes had one or more identifiable causes rooted in human error, mechanical failure, or corporate negligence. If you have been hurt in a collision with a commercial truck, a San Antonio personal injury lawyer at J.A. Davis & Associates can investigate the cause of your truck accident and build a case that gets results. The firm’s truck accident attorneys have over 25 years of experience fighting for injured Texans.

The Texas Department of Transportation data for 2024 confirms that Bexar County is the third most dangerous county in Texas for truck accidents, behind only Harris and Dallas. The causes of these crashes are varied, but certain factors appear repeatedly in crash investigations conducted by law enforcement, federal regulators, and attorneys representing injured victims. Driver error, including distracted driving, speeding, and impaired driving, is the most frequently cited cause. Mechanical failures involving brakes, tires, and steering systems account for a significant number of crashes. And systemic problems within the trucking industry, including inadequate training, poor maintenance practices, and pressure to violate safety regulations, create the conditions in which truck accidents in San Antonio occur at an alarming rate. The truck accident lawyers at J.A. Davis & Associates investigate every one of these factors when building cases for their clients.

What makes determining the cause of a truck accident in San Antonio particularly complex is that commercial vehicle crashes often involve multiple contributing factors operating simultaneously. A driver who is fatigued may also be driving a truck with worn brake pads on an overloaded trailer in a construction zone. Each of those factors compounds the danger, and each may point to a different liable party. The truck accident attorneys at J.A. Davis & Associates have the experience and resources to identify every contributing cause and pursue every available source of recovery.

Driver Error — The Most Common Cause of Truck Accidents

The majority of truck crashes in San Antonio and across Texas are caused at least in part by driver error. Distracted driving has become an epidemic in the trucking industry as drivers use cell phones, GPS devices, dispatch systems, and other electronic devices while operating vehicles that require their full attention. Texting while driving a commercial vehicle is a federal violation that carries significant penalties, yet enforcement is difficult and the practice remains widespread.

Speeding and aggressive driving are additional driver-related factors that contribute to truck accidents in the San Antonio area. Commercial trucks require far greater stopping distances than passenger vehicles, and a truck traveling even five miles per hour above the speed limit may need hundreds of additional feet to come to a stop. When a truck driver follows too closely, changes lanes aggressively, or fails to adjust speed for traffic conditions, the risk of a catastrophic collision increases dramatically.

Mechanical Failures and Maintenance Deficiencies

Brake failures are one of the most terrifying causes of truck accidents because they can render a fully loaded truck completely unable to stop. Federal regulations require regular brake inspections and maintenance, and truck drivers are required to perform pre-trip inspections before every driving shift. When trucking companies defer maintenance to keep trucks on the road generating revenue, and when drivers skip or falsify pre-trip inspections, the result can be a truck with failing brakes hurtling through San Antonio traffic.

Tire blowouts, steering malfunctions, lighting failures, and trailer coupling problems are additional mechanical causes of truck accidents. Defective equipment manufactured by third-party suppliers may also contribute to crashes, opening the door to product liability claims against manufacturers in addition to negligence claims against the trucking company.

Impaired Driving

Truck drivers who operate commercial vehicles under the influence of alcohol, illegal drugs, or certain prescription medications pose an extreme danger to everyone on the road. Federal regulations set a blood alcohol limit of 0.04 percent for commercial vehicle operators, half the legal limit for passenger vehicle drivers. The FMCSA also requires pre-employment, random, post-accident, and reasonable-suspicion drug testing for commercial drivers. When trucking companies fail to implement these testing programs or ignore positive results, they create conditions for impaired driving crashes that can be fatal.

Cargo-Related Causes

Improperly loaded, overweight, or unsecured cargo contributes to truck accidents by affecting the vehicle’s stability, handling, and stopping ability. An overweight truck needs more distance to stop and places additional stress on brakes and tires. Cargo that shifts during transit can cause a truck to become unbalanced and roll over, especially during turns or lane changes. Federal cargo securement regulations specify requirements for different types of loads, and violations of these rules are common in the industry.

Inadequate Training and Hiring Practices

The trucking industry’s chronic driver shortage has led some companies to lower their hiring standards and place inadequately trained drivers behind the wheel of commercial vehicles. Drivers who lack experience operating specific types of equipment, navigating urban traffic, or handling emergency situations are more likely to be involved in preventable crashes. Negligent hiring and training practices are a form of corporate negligence that can result in significant liability for the trucking company.
