A three-vehicle crash involving two semi-trucks and a passenger vehicle caused major lane closures on Interstate 35 near Temple, Texas, on Monday, June 29, 2026. According to the Temple Police Department, the crash occurred near exit 297 between Belton and Temple and affected both the northbound and southbound lanes of I-35. Officials initially reported that two lanes were closed in each direction, leaving traffic moving through only one lane while crews responded to the scene and worked to clear the roadway. The closed lanes were later reopened. Authorities reported that one person was taken to the hospital.
According to officials, one semi-truck carrying rocks was traveling northbound and attempted to slow down to avoid another semi-truck ahead of it. When the driver realized the truck would not slow down in time, the driver swerved. The semi-truck then jackknifed, with the front of the truck crossing over the barrier and ending up in the opposite lanes. Officials said the load did not tip over, but fuel leaked onto the highway. The jackknifed semi-truck struck the semi-truck in front of it and also collided with a passenger vehicle behind it. All three vehicles had been traveling northbound before the crash sequence unfolded.
This incident highlights how quickly a commercial vehicle emergency can escalate on a busy interstate. When a loaded semi-truck loses control, crosses a barrier, leaks fuel, and involves multiple vehicles, investigators must carefully examine the driver’s actions, vehicle condition, cargo weight, braking systems, roadway conditions, and trucking company safety practices.
Why Jackknife Crashes Are So Dangerous
A jackknife accident occurs when the tractor and trailer fold at an angle, often causing the truck driver to lose control of the vehicle’s path. These crashes can block several lanes, sweep across traffic, strike nearby vehicles, or send parts of the tractor-trailer into oncoming lanes. On a major corridor like I-35, the consequences can be severe because traffic volume is high and drivers may have little time to react.
Jackknife crashes are especially dangerous when a truck is carrying a heavy load. In this case, officials reported that the semi-truck was carrying rocks. Even when cargo does not spill, the weight of the load can affect stopping distance, braking response, trailer movement, and the truck’s ability to remain stable during an emergency maneuver. A sudden swerve while attempting to avoid another vehicle can cause the trailer to swing outward, creating a chain reaction involving multiple lanes and vehicles.
Investigators will likely examine whether the truck was traveling at a safe speed for traffic conditions, whether the driver was following too closely, whether braking systems performed properly, and whether the cargo weight or load distribution affected the truck’s ability to stop safely.
Rear-End Collision Questions After the Temple I-35 Crash
Based on the facts reported by authorities, the crash sequence began when the rock-hauling semi-truck attempted to slow down for another semi-truck ahead. That makes the circumstances similar to many serious commercial vehicle crashes involving sudden braking and insufficient stopping distance. A rear-end collision involving an 18-wheeler can be far more dangerous than a typical passenger vehicle crash because of the truck’s size, weight, and longer stopping distance.
Commercial trucks require significantly more distance to stop than passenger vehicles, particularly when they are fully loaded. If a truck driver follows too closely, becomes distracted, reacts late, or encounters a mechanical problem, the driver may be unable to avoid traffic ahead. When that happens, a sudden evasive maneuver may create a secondary danger, such as a jackknife or lane departure.
Investigators may consider whether the semi-truck driver maintained a safe following distance, whether traffic slowed suddenly, whether roadway conditions affected braking, and whether any other vehicle movement contributed to the emergency.
Cargo Weight and Shifting Loads May Be Investigated
Officials said the truck was carrying rocks and that the load did not tip. Even so, the nature of the load may remain important to the investigation. Heavy cargo can affect acceleration, braking, balance, and the forces placed on the tractor and trailer during an evasive maneuver.
If cargo is improperly loaded or unevenly distributed, the truck may become more difficult to control. In some crashes, shifting cargo can contribute to a rollover, jackknife, or loss of control. Investigators may review weight tickets, loading records, cargo securement procedures, and whether the vehicle complied with applicable weight limits.
If the truck was overloaded or the load was not properly balanced, that could affect liability. An overloaded 18-wheeler can be harder to stop and more difficult to control during sudden braking. Even when cargo remains inside the trailer or bed, excess weight can increase stopping distance and place additional stress on tires, brakes, suspension components, and steering systems.
Fuel Leaks Create Additional Hazards After a Truck Crash
Temple officials reported that fuel leaked onto the highway after the crash. Fuel leaks are serious because they create fire risks, environmental concerns, cleanup issues, and added danger for first responders and other motorists. A crash scene involving leaking fuel must often be secured quickly to prevent ignition sources, protect emergency crews, and keep traffic away from hazardous areas.
Although officials did not report a fire, fuel leaks can increase the risk of burn injuries if vapors ignite or if damaged equipment produces sparks. Investigators may examine whether the truck’s fuel tanks, lines, or protective systems were damaged during the impact and whether any vehicle defect or maintenance issue worsened the leak.
Mechanical Issues and Braking Performance
Because the reported crash began when a semi-truck attempted to slow down and could not do so in time, investigators may closely review the truck’s braking system. A commercial vehicle’s brakes must be properly inspected, adjusted, maintained, and repaired. Problems with brake components can significantly increase stopping distance and make an emergency situation more dangerous.
Potential brake failure issues may include worn brake pads, air brake system defects, poor adjustment, inadequate maintenance, or failures that reduce braking power. Even if the brakes did not fail completely, partial braking deficiencies can matter when a loaded truck must slow quickly in traffic.
Investigators may also examine tires, steering components, suspension systems, and coupling devices. A steering malfunction can make it difficult for a driver to regain control after a sudden maneuver, while a tire blowout can cause a driver to lose control, particularly at highway speeds.
Driver Logs, Fatigue, and Federal Safety Rules
Commercial truck drivers and trucking companies are subject to federal safety regulations intended to reduce preventable crashes. After a serious multi-vehicle trucking collision, investigators often review driver logs, electronic records, inspection documentation, and dispatch communications.
Compliance with hours of service regulations may be relevant if fatigue affected the driver’s reaction time, judgment, speed control, or following distance. Fatigue can make it harder for a truck driver to recognize slowing traffic and respond appropriately. In some cases, driver fatigue contributes to delayed braking, lane drift, poor decision-making, or overcorrection.
Investigators may also examine whether an electronic logging device recorded the driver’s hours, route, duty status, and vehicle movement before the crash. If records show violations, missing data, or inconsistencies, those issues may become important in determining whether the trucking company followed safety rules.
Pre-Trip Inspections and Vehicle Maintenance
Before operating a commercial truck, drivers are expected to inspect key safety systems. A proper pre-trip inspection may identify problems with brakes, tires, lights, steering, mirrors, coupling equipment, emergency equipment, and other critical components. If a defect existed before the truck entered I-35, investigators may ask whether it should have been found and fixed before the trip began.
Commercial carriers are also responsible for maintaining their trucks in safe operating condition. If inspection records show recurring brake problems, steering complaints, tire issues, or other maintenance concerns, those records could become important. Prior out-of-service violations may also provide evidence that a truck or carrier had safety problems before the crash.
A trucking company cannot safely operate heavy vehicles on public highways without reliable inspection and maintenance practices. When maintenance failures contribute to a crash, the company may be held responsible.
Black Box Data and Crash Reconstruction
Modern commercial vehicles often contain electronic systems that record important information before and during a crash. Black box data may show speed, braking, throttle use, engine activity, and other information that helps explain what happened before impact.
In a crash involving a jackknife, barrier impact, fuel leak, and multiple vehicles, electronic data can be especially important. It may help answer questions such as how fast the truck was traveling, when the driver began braking, whether the brakes were applied fully, whether the driver swerved before or after braking, and how quickly the crash sequence unfolded.
Dash camera footage, traffic cameras, witness statements, roadway markings, vehicle damage, and physical evidence may also help investigators reconstruct the crash. Because commercial trucking companies may have access to important electronic records soon after a crash, prompt preservation of evidence is often critical.
Trucking Company Liability After an I-35 Semi-Truck Crash
Responsibility for a crash involving a commercial truck may extend beyond the individual driver. Trucking company liability may arise when a company fails to maintain its vehicles, hires unqualified drivers, ignores safety violations, pressures drivers to meet unrealistic schedules, fails to train employees, or allows unsafe equipment to remain in service.
Investigators may review the driver’s safety history, hiring file, training records, medical certification, maintenance logs, dispatch records, and company policies. They may also examine whether the company placed improper dispatch pressure on the driver, whether the route was reasonable, and whether the carrier had procedures in place to prevent crashes involving heavy loads.
If investigators identify an FMCSA violation involving maintenance, driver qualification, hours of service, cargo securement, or vehicle inspection, that violation may become significant evidence in a civil claim.
Why This Crash Matters for Texas Drivers
I-35 is one of the busiest commercial corridors in Texas. Tractor-trailers, construction vehicles, passenger cars, and local traffic frequently share congested lanes. When a semi-truck jackknifes near a barrier and enters opposing lanes, the risk to surrounding motorists is substantial. Even when injuries are initially described as minor, crashes like this can cause delayed pain, soft tissue injuries, back injuries, concussions, and emotional trauma.
Any person injured in an 18-wheeler accident should seek medical care, preserve photographs and records, and avoid assuming the initial crash report contains the full story. Commercial vehicle collisions often require deeper investigation into driver behavior, company practices, mechanical condition, and electronic data.
