Brock Junction, TX — February 5, 2026, one person was injured due to a truck accident just after 12:00 midnight along Interstate Highway 20.

According to authorities, a 45-year-old man was traveling in a westbound Kenworth 18-wheeler with a trailer in tow on I-20 in the vicinity west of Brock Spur when the accident took place.

Officials indicate that, for as yet unknown reasons, the truck failed to safely maintain its lane of travel. It was consequently involved in a single-vehicle collision in which it apparently overturned. The man reportedly sustained serious injuries over the course of the accident.

Additional details pertaining to this incident—including the identity of the victim—are not available at this point in time. The investigation is currently ongoing.

When an 18-wheeler overturns after failing to maintain its lane just after midnight, the first question I ask is: why did the truck drift or move out of its lane to begin with? Tractor-trailers don’t typically wander off course without a cause.

It’s not clear whether the truck gradually drifted, made a sudden steering correction, or encountered something in the roadway. We don’t yet know if fatigue, distraction, or a mechanical issue played a role. At that hour, fatigue is always a legitimate concern. Investigators will need to examine the driver’s hours-of-service records to determine how long he had been behind the wheel.

Lane departure followed by a rollover often suggests overcorrection. When a heavy truck’s tires leave the paved surface and hit the shoulder, drivers sometimes steer sharply back onto the roadway. That abrupt input can shift the truck’s center of gravity and cause it to tip, especially if the trailer is loaded. We don’t yet know whether that sequence occurred here, but it’s a common pattern in single-vehicle truck crashes.

Engine control module data should provide important clues. That data can show speed, braking, and steering-related inputs in the seconds before the truck overturned. If the data shows a sudden steering maneuver or hard braking, that may indicate the driver was reacting to something. If there was little corrective action, investigators may look more closely at distraction or drowsiness.

Mechanical condition is another area that needs careful review. Were the tires properly inflated? Was there any evidence of a blowout or steering component failure? A mechanical problem can trigger a lane departure quickly, especially at highway speeds.

Single-vehicle rollovers are often described as straightforward, but the real explanation usually lies in the details—timing, driver input, equipment condition, and load stability. Those answers will come from data downloads, vehicle inspection, and a careful reconstruction of how the truck moved before it tipped.

Key Takeaways

• The central issue is why the truck failed to maintain its lane.
• Fatigue, overcorrection, mechanical failure, or distraction are possible factors.
• Black box data can clarify speed and steering before the rollover.
• Shoulder drop-offs and abrupt corrections often lead to truck tip-overs.
• A full investigation requires both driver record review and mechanical inspection.
