18-Wheeler Wrecks
Overturned 18-Wheeler and Oil Spill Shut Down I-30 in Royse City

Wooley Law Takeaway
An overturned 18-wheeler and resulting oil spill shut down Interstate 30 in both directions in Royse City Thursday evening, September 3, 2026, with the closure continuing into Friday morning.
Police said the truck crash occurred at approximately 6:30 p.m. near mile marker 79 on I-30.
The 18-wheeler overturned onto its side and spilled oil across the interstate. Emergency and cleanup crews worked through the night, and traffic was still being diverted in both the eastbound and westbound directions as of approximately 6:00 a.m. Friday, September 4.
Authorities had not released information regarding injuries or what caused the truck to overturn.
Both Directions of I-30 Closed After Royse City 18-Wheeler Crash
The wreck created a significant traffic disruption along the I-30 corridor through Royse City, east of Rockwall and the Dallas-Fort Worth area.
Because oil spilled onto the roadway, crews had to do more than simply remove the overturned tractor-trailer. Cleanup operations continued overnight to address the spill and make the interstate safe for traffic.
As of early Friday morning, motorists were being diverted away from the interstate in both directions. Authorities had not provided an estimated time for the highway to fully reopen.
Drivers traveling between Royse City, Fate, Rockwall, Greenville, and communities east of Dallas could experience significant delays.
What Caused the 18-Wheeler to Overturn?
Authorities have not yet publicly explained why the tractor-trailer rolled onto its side.
An overturned commercial truck can require investigators to consider a number of possible factors, including:
Vehicle speed before the rollover
A sudden steering or evasive maneuver
An unsafe lane change
Driver distraction or fatigue
Tire failure
Brake or steering problems
Cargo shifting inside the trailer
Improper cargo loading or weight distribution
Contact with another vehicle
Construction or changing lane configurations
Roadway or weather conditions
There is currently no information establishing that any particular one of these factors caused the Royse City wreck.
Electronic Truck Data Could Show What Happened Before the Rollover
An I-30 18-wheeler rollover can leave behind electronic evidence that helps reconstruct the moments before the truck lost control.
The tractor's electronic control module may record information concerning speed, braking, throttle position, and other vehicle activity.
Other evidence may include electronic logging-device records, GPS and telematics information, onboard camera footage, dispatch communications, driver hours-of-service records, inspection reports, and maintenance records.

Oil Spill Makes the I-30 Crash More Complicated
The reported oil spill creates another important part of the investigation.
Investigators may need to determine where the oil came from, how much was released, whether the spill occurred when the truck overturned, and whether any damaged fuel or mechanical components contributed to the length of the highway closure.
Photographs and video taken before cleanup may be important because the scene can change substantially once the truck is uprighted, fluids are removed, and the roadway is reopened.
The tractor and trailer themselves may also need to be preserved for inspection before they are repaired or returned to service.
Trucking Company Records May Need to Be Preserved
If someone was injured in the Royse City crash, evidence held by the motor carrier may become important.
Depending on the circumstances, investigators may seek the truck driver's qualification file, driving schedule, electronic logs, onboard camera video, GPS history, dispatch communications, pre-trip inspection records, maintenance history, tire records, brake records, cargo information, and electronic vehicle data.
Some electronic evidence may be overwritten during ordinary business operations. Early preservation can therefore be especially important after a serious commercial truck crash.
I-30 Is a Major Trucking Corridor Through Royse City
Interstate 30 carries substantial passenger and commercial traffic between Dallas, Garland, Rowlett, Rockwall, Fate, Royse City, Greenville, and Northeast Texas.
The Wooley Law Firm recently reported on another 18-wheeler crash that closed westbound I-30 at FM 3549 near Rockwall and has previously reported on a major I-30 wreck in Royse City.
Those crashes involved different circumstances and are not related to Thursday evening's rollover.

Major 18-Wheeler Crash on Northbound US 75 at Melissa Road Closes Two Left Lanes
A major collision involving an 18-wheeler on northbound U.S. 75 at Melissa Road in Melissa caused traffic delays early Monday morning, October 19, 2026. The wreck was reported at approximately 5:30 a.m. and resulted in the closure of the two left northbound lanes while emergency crews responded. Additional information about the other vehicles involved and possible injuries has not yet been released. What Happened in the US 75 18-Wheeler Crash at Melissa Road?

With two left lanes blocked during the early morning commute, motorists traveling north through Collin County could encounter significant delays until the scene is cleared. Because this is a developing incident, no conclusions should be drawn about fault until investigators determine how the collision occurred. Evidence That May Matter After an 18-Wheeler Crash Commercial truck collisions can involve evidence that is not typically available in an ordinary passenger-vehicle wreck. Potentially important evidence may include: Electronic control module data Electronic logging-device records GPS and telematics information Dash-camera footage Driver qualification and training records Hours-of-service records Tractor and trailer inspection records Maintenance records Dispatch communications Crash-scene photographs and measurements Witness statements This evidence may help determine the truck’s speed, braking activity, lane position, and movements immediately before the collision. Why Trucking Evidence Should Be Preserved Quickly Electronic and company records can be important after a serious commercial truck wreck, but some information may be overwritten or become more difficult to obtain over time. An investigation may need to identify the trucking company, truck owner, trailer owner, driver’s employer, maintenance provider, and other entities connected to the commercial vehicle. Preserving the tractor, trailer, electronic data, onboard video, and company records can help establish how the wreck occurred and whether any safety issue contributed.

Wrong-Way Driver Killed in Fatal I-20 18-Wheeler Crash at Spur 408 in Dallas
A fatal crash involving an 18-wheeler and a suspected wrong-way driver on Interstate 20 at Spur 408 in Dallas shut down the highway early Monday morning, October 19, 2026. According to Dallas Fire-Rescue, emergency crews responded shortly after 3:00 a.m. Police believe one of the motorists was traveling the wrong way when the collision occurred. The suspected wrong-way driver was killed. The other driver was transported to a hospital. The wreck involved an 18-wheeler, making the investigation especially important because commercial trucks may contain electronic and company records that can help reconstruct what occurred. The crash caused significant closures on I-20 near Spur 408 while police and emergency crews investigated. What Happened in the Fatal I-20 18-Wheeler Crash? The collision occurred on I-20 near Spur 408 and involved an 18-wheeler and another vehicle. Preliminary information indicates that one of the vehicles was traveling in the wrong direction before the crash. One driver died, while the other was hospitalized. Authorities have not yet released complete information explaining where the wrong-way vehicle entered I-20, how long it had been traveling against traffic, or the full sequence of events leading to the collision. Why an 18-Wheeler Crash Requires a Separate Investigation When a commercial truck is involved in a serious or fatal collision, important evidence may exist beyond the police crash report. Potential evidence can include: Electronic control module data Electronic logging-device records GPS and telematics information Dash-camera or onboard video Driver qualification records Hours-of-service records Dispatch communications Tractor and trailer inspection records Maintenance records Crash-scene photographs and measurements Witness statements This information can help determine the truck’s speed, braking activity, location, and movements immediately before impact. Evidence May Help Determine Where the Wrong-Way Driver Entered I-20 Investigators may also look for traffic-camera footage, surveillance video, dash-camera recordings, roadway signs, pavement markings, and witness accounts to determine where the wrong-way vehicle entered the freeway. That evidence may establish whether the vehicle entered through an exit ramp, crossed a median, or began traveling the wrong direction through some other sequence of events. At this time, authorities have not publicly confirmed how the driver ended up traveling against traffic. Can an 18-Wheeler Driver or Trucking Company Be Liable? Liability depends on the evidence. The presence of an 18-wheeler does not automatically mean that the truck driver or trucking company was responsible for the wreck. If the other vehicle entered I-20 in the wrong direction, that conduct may be a major factor in determining fault. However, investigators should still preserve and review the commercial truck’s electronic data, onboard video, driver records, and other evidence before reaching conclusions.
