Last reviewed by Andrew J. Wooley, Attorney
A crash with an 18-wheeler, tractor-trailer, delivery truck, dump truck, or other commercial motor vehicle can change your life in seconds. Large commercial trucks are much bigger and heavier than passenger vehicles. Many commercial trucks can weigh up to 80,000 pounds. Victims often suffer serious injuries, expensive medical bills, missed work, and long-term uncertainty about their future.
If you were hurt in a truck accident in Duncanville, Texas, you may already be receiving calls from the trucking company's insurance carrier. The adjuster may ask for a recorded statement, offer a quick settlement, or try to blame you before the full investigation is complete. Before you speak with the insurance company, talk to a Duncanville 18-wheeler accident lawyer who understands how serious truck wreck claims are handled.
At The Wooley Law Firm, Andrew J. Wooley represents injured Texans after serious commercial truck accidents. His background includes experience in personal injury law and work within the insurance industry for large corporations. That insight helps him understand how insurance companies evaluate injury claims, defend trucking companies, and look for ways to reduce what victims are paid.
Duncanville is a city of 40,706 people (2020 census) in southwestern Dallas County, part of the Best Southwest area with Cedar Hill, DeSoto, and Lancaster. Interstate 20 crosses the city, with Duncanville exits at Cedar Ridge Drive, Duncanville Road and Main Street, and Cockrell Hill Road and Camp Wisdom Road. U.S. Highway 67 runs along the city's eastern edge, with exits at Wintergreen Road, South Main Street, Danieldale Road, Cockrell Hill Road, and Wheatland Road. Local drivers regularly share these roads with 18-wheelers, delivery trucks, construction vehicles, dump trucks, box trucks, and other commercial motor vehicles.
Truck traffic is especially common on and around:
Duncanville's location makes it a regular route for freight, delivery, construction, warehouse, and service vehicles moving through southern Dallas County and the broader DFW area. Trucks traveling through Duncanville may be headed to distribution centers, construction sites, retail facilities, or other commercial destinations throughout North Texas.
When truck drivers, trucking companies, cargo loaders, maintenance providers, or other commercial operators cut corners, innocent people can suffer the consequences. A careless decision involving an 18-wheeler or commercial vehicle can lead to a serious crash, catastrophic injuries, and long-term financial hardship for victims and their families.
Commercial motor vehicle crashes are not rare in Duncanville. According to TxDOT C.R.I.S. Query data, there were 39 reported crashes involving commercial motor vehicles in Duncanville, Texas in 2026 as of November 11, 2026, resulting in 4 injuries and no fatalities. Crash reports can take two weeks or longer to appear in TxDOT data: Texas law gives investigating officers up to 10 days to file a report, and TxDOT says a report can take up to 14 days from the crash date to appear in its search results. These totals may change as more reports are processed.
The data showed that Duncanville commercial motor vehicle crashes occurred on major routes including the routes below, sized by 2026 crash count:
Many commercial trucks and trailers can weigh up to 80,000 pounds. When a vehicle that large hits a passenger car, pickup, motorcycle, or SUV, the injuries can be devastating.
Truck accident cases are often more complex than ordinary car wreck claims. A serious crash may involve a careless driver, an unsafe trucking company, improper cargo loading, poor maintenance, or multiple responsible parties.
TxDOT C.R.I.S. Query data lists 16 Duncanville crashes in 2026, as of November 11, 2026, that involved an 18-wheeler (a tractor pulling a semi-trailer). Changing lanes when unsafe was cited in 8 of those crashes, and no other single factor was listed in more than two. Because the number of crashes is small, these counts can change quickly as more reports are processed. The factors listed can apply to any driver involved, not only the truck driver, and some reports cite only a general "other" factor.
Unsafe lane changes are a common issue in truck accident cases. Truck drivers must check blind spots, signal properly, and make sure lanes are clear before moving over. An unsafe lane change by a tractor-trailer can force a smaller vehicle off the road, crush a vehicle between lanes, or trigger a chain-reaction crash. On Interstate 20 and U.S. Highway 67, where traffic merges and exits at busy interchanges, conditions can change quickly.
Driver inattention is another common issue in truck accident cases. Distracted driving can include texting, looking at dispatch devices, eating, adjusting navigation systems, or simply failing to watch traffic ahead. When an 18-wheeler driver is distracted or inattentive, even a few seconds can be enough to cause a rear-end collision, sideswipe, underride crash, or multi-vehicle wreck.
Failure to drive in a single lane is also a common issue in truck accident cases. When a truck drifts out of its lane, its size leaves little room for nearby drivers to react. Fatigue, distraction, and narrowed lanes in construction zones can all play a part.
Other common issues in truck accident cases may include:
A thorough investigation is often necessary to determine exactly what happened and who may be legally responsible.
One of the biggest roadway issues affecting Duncanville drivers is the meeting of two major freeways. Interstate 20 crosses the city and U.S. Highway 67 runs along its eastern edge; the two freeways meet at an interchange just east of Duncanville, in Dallas. Commuters, delivery vehicles, and 18-wheelers share the same ramps and frontage roads on both freeways. TxDOT C.R.I.S. data shows that Interstate 20 carried most of the reported commercial motor vehicle crashes in Duncanville in 2026, 21 of the city's 39, followed by U.S. Highway 67 and Duncanville Road.
Work on these highways continues. As of September 2026, TxDOT reported bridge maintenance on U.S. Highway 67 at the Interstate 20 interchange and at Wheatland Road as about 90% complete.
For Duncanville drivers, these conditions can mean frequent merging, lane changes, and sudden slowdowns near interchanges and work zones. They can become especially dangerous when truck drivers speed, follow too closely, make unsafe lane changes, fail to control their speed, or react improperly to changing traffic.
An 18-wheeler accident claim is not just a bigger car accident case. Trucking cases often involve federal and state safety rules, corporate defendants, commercial insurance policies, and evidence that may disappear if it is not preserved quickly. Depending on the facts, responsible parties may include the truck driver, trucking company, trailer owner, cargo loader, maintenance contractor, freight broker, parts manufacturer, or another negligent motorist.
The insurance company may begin investigating immediately after the crash. Its goal is usually to protect the trucking company and limit financial exposure. Your lawyer's job is to protect your claim, preserve evidence, and build the strongest case possible. Some trucking evidence may be lost, overwritten, repaired, or destroyed if action is not taken quickly. An attorney can send preservation letters, identify potential defendants, request key records, inspect the vehicles when appropriate, and work to prevent important evidence from disappearing.
Because of the size and weight of commercial trucks, victims may suffer life-changing injuries. Common injuries in Duncanville truck accident cases include:
Even injuries that seem manageable at first can become serious over time. You should get medical care as soon as possible after a truck accident and follow your doctor's instructions.
Every case is different, but an injured person may be able to pursue compensation for losses such as:
If a truck accident causes a death, surviving family members may have a wrongful death claim. These cases require careful legal attention because the eligible claimants, available damages, and evidence can differ from a standard injury case.
If you were injured in an 18-wheeler accident, delivery truck crash, dump truck wreck, or other commercial motor vehicle collision in Duncanville, do not assume the trucking company or insurance carrier will treat you fairly. Their goal is to protect their financial interests. Your goal should be to protect your health, your claim, and your future.
