On Monday evening, an 18-wheeler fell from an overpass along the eastbound US 83 Relief Route between Peñitas and Palmview. Authorities report that the tractor portion of the semi-truck became dislodged and dropped from the overpass, striking a vehicle traveling below. Both occupants of the car and the truck driver were hospitalized with injuries. At this time, the accident remains under investigation.
For me, crashes involving semi-trucks falling from an overpass raise serious questions about both the driver’s control of the vehicle and the condition of the vehicle itself.
Could Driver Distraction or Fatigue Have Played a Role?
One of the first questions I’d want answered is whether the truck driver was fully alert and focused in the moments leading up to the crash. Long hours, demanding schedules, and overnight driving can all contribute to fatigue, which remains a leading cause of serious truck crashes. Investigators should look into the driver's hours-of-service log to determine if rest requirements were met. In addition, cellphone records, in-cab video, and statements from the driver could help reveal whether distraction—such as texting or reaching for an item—might have contributed to the loss of control.
Could Mechanical Failure or Improperly Loaded Cargo Have Played a Role?
Mechanical issues such as brake failure, steering problems, or suspension defects can also have serious consequences—especially on elevated stretches of highway. If a mechanical failure caused the truck to leave the roadway or the tractor to separate from the trailer, it’s critical that investigators examine service records, perform a detailed inspection of the wreckage, and determine if any part malfunctioned. These types of issues may also raise questions about maintenance practices and fleet oversight.
Additionally, improperly loaded or unsecured cargo can affect a semi-truck’s balance and handling, especially during turns or lane changes. If the truck’s load shifted suddenly, it could have contributed to the driver losing control or caused the trailer to separate. Investigators should review bills of lading, cargo securement practices, and weigh station records to determine whether the load was safely distributed and properly restrained.
What Types of Evidence Should Investigators Examine?
To understand how the crash occurred, investigators should review Engine Control Module (ECM) data and collect statements from eyewitnesses or other drivers. Any available dashcam footage or traffic surveillance video could also provide important insight into the truck’s speed, lane position, and the moment the vehicle left the overpass. Maintenance logs, cargo documentation, and post-crash vehicle inspections will all be vital to painting a full picture of what happened.
Why Even Ask These Questions?
When a semi-truck ends up off an overpass, it’s a sign that something went seriously wrong—whether due to driver actions, mechanical failure, or improperly loaded cargo. In my experience, it’s not always immediately clear what chain of events led to the crash. That’s why a thorough investigation is essential: it helps identify all contributing factors, ensures accountability, and gives those affected a clearer understanding of why the crash happened in the first place.
