Semi-truck accidents in San Antonio take many forms, each with severe consequences for victims. Rollover accidents frequently occur on highways like I-35 and I-10, where speeding, sharp curves, or improperly loaded cargo can cause trucks to overturn. Jackknife truck accidents near San Antonio are commonplace. They are often caused by sudden braking or wet road conditions, result in the trailer swinging into adjacent lanes, endangering other vehicles.

Rear-end collisions are common in congested areas, particularly during rush hour or near industrial zones. Semi-trucks require significantly longer stopping distances than passenger vehicles, making these accidents especially devastating. Right-turn accidents often occur in urban areas like Downtown San Antonio, where semi-truck drivers misjudge their turning radius or fail to account for cyclists, pedestrians, or smaller vehicles. Underride accidents, where smaller vehicles slide beneath a semi-truck, are among the deadliest. Despite federal requirements for underride guards, poor maintenance often renders these safety features ineffective.

San Antonio shares many challenges with Houston, Texas, another large Texas city with significant semi-truck traffic and industrial activity. Both cities experience high accident rates due to oversized loads, illegal parking on shoulders, and busy urban streets congested with delivery and industrial trucks.
