One person was killed Wednesday night following a serious crash involving an 18-wheeler on Interstate 45 near Buffalo in Leon County, according to the Texas Department of Public Safety.
The collision occurred around 10:00 p.m. on December 18, 2025, near Exit 178 on southbound I-45. DPS officials said a passenger vehicle had become disabled in the inside lane of traffic when it was struck from behind by a southbound 18-wheeler. The driver of the passenger car, identified as 33-year-old Dontavis Hood of Missouri City, was pronounced dead at the scene.
Authorities reported that the initial impact led to a secondary collision. After striking the disabled vehicle, the 18-wheeler collided with an SUV traveling in the same lane, pushing it through a cable barrier and into the northbound lanes of traffic. Three occupants were inside the SUV at the time and were reported to have possible injuries.
Interstate 45 was shut down for several hours while emergency crews responded and worked to clear the scene. DPS later confirmed that the roadway has since reopened. The crash remains under investigation.
Rear-End Collisions and Commercial Trucking Risks
Crashes involving large commercial trucks often result in severe outcomes due to the size and weight of an 18-wheeler. A rear-end collision can be especially dangerous when traffic is stopped or slowed unexpectedly, leaving little time or distance for a heavy truck to brake safely.
Investigators typically examine whether the truck driver had sufficient visibility, reaction time, and stopping distance to avoid the collision. Factors such as speed, roadway conditions, and vehicle maintenance may all play a role in understanding how the crash unfolded.
Factors That May Be Examined in the Investigation
In crashes of this nature, authorities often review whether mechanical issues contributed to the collision. Problems such as brake failure can significantly reduce a truck’s ability to stop in emergency situations, particularly at highway speeds.
Investigators may also analyze whether the commercial vehicle complied with required safety protocols, including completion of a proper pre-trip inspection and adherence to federal hours of service regulations designed to prevent driver fatigue.
Electronic records and black box data may also be reviewed to assess vehicle speed, braking activity, and driver inputs in the moments leading up to the crash.
Chain-Reaction Crashes and Secondary Impacts
The secondary collision involving the SUV highlights how crashes with commercial trucks can quickly escalate into multi-vehicle incidents. Once an 18-wheeler loses control or is unable to stop, the resulting force can push other vehicles into barriers, opposing lanes of traffic, or additional hazards.
These chain-reaction crashes increase the risk of severe injuries, including spinal injury, traumatic brain trauma, and other life-altering harm for motorists caught nearby.
Legal Considerations After a Fatal 18-Wheeler Accident
Fatal crashes involving commercial trucks often raise complex legal questions about responsibility and safety compliance. Determining liability may require an in-depth review of driver conduct, company safety practices, vehicle maintenance records, and preserved evidence from the scene.
Families affected by a fatal 18-wheeler accident may need to understand how fault is evaluated and how the burden of proof applies once investigators complete their findings. In some cases, multiple parties may share responsibility for the conditions that led to the crash.
