Most Dangerous Roads for Truck Accidents in Dallas-Fort Worth

North Texas Highways Are Among the Most Dangerous for Truck Accidents in the Country

The Dallas-Fort Worth metroplex is one of the largest freight hubs in the United States. With massive distribution centers in Alliance, Southern Dallas, and along the I-35 corridor, thousands of 18-wheelers crisscross North Texas highways every day. That volume of heavy commercial traffic creates serious risks for passenger vehicle drivers — particularly on the highways that connect Frisco, Plano, McKinney, Dallas, and the surrounding communities.

According to the Texas Department of Transportation, Texas leads the nation in fatal truck accidents, and the DFW region accounts for a disproportionate share of those crashes. Understanding which roads carry the highest risk can help you stay safe — and if you have already been involved in a crash, knowing the specific hazards of the road where your accident occurred strengthens your legal claim.

Interstate 35 (I-35 and I-35E)

I-35 is one of the most dangerous highways for truck accidents in all of Texas. This north-south interstate carries enormous volumes of commercial freight from Mexico through San Antonio, Austin, Waco, and into the DFW metroplex. Through Dallas, the corridor narrows, merges with heavy local commuter traffic, and creates conditions that lead to catastrophic 18-wheeler crashes.

The stretch of I-35E between downtown Dallas and Denton is particularly hazardous. Construction zones, narrow lanes, high-speed merges, and the mix of commuter and commercial traffic create a volatile combination. Truck accident victims on I-35 through the Lewisville, Carrollton, and Denton County area should be aware that these crashes often involve multiple liable parties including out-of-state carriers.

Interstate 635 (LBJ Freeway)

The LBJ Freeway is one of the busiest highways in Texas. The managed toll lanes and complex interchange system create dangerous weaving patterns where 18-wheelers must navigate between express lanes and general-purpose lanes. The I-635 and US-75 interchange in Richardson and the I-635 and I-35E junction are both high-frequency crash zones for commercial trucks. Trucks transitioning between lanes at highway speed in heavy traffic are a leading cause of sideswipe and lane-departure crashes on this corridor.

US Highway 75 (Central Expressway)

US-75 runs directly through Plano, McKinney, Allen, and into Collin County — the heart of Ford Law’s service area. This heavily traveled corridor connects Dallas to the rapidly growing northern suburbs. While US-75 has been modernized in sections, the mix of local traffic, commercial deliveries, and through-traffic creates high-risk conditions, especially during rush hour. Truck accidents on US-75 in Plano and McKinney frequently involve rear-end collisions during stop-and-go traffic conditions.

State Highway 121 (Sam Rayburn Tollway)

Highway 121 connects Frisco, The Colony, Lewisville, and Grapevine — and feeds directly into DFW Airport’s freight operations. This means heavy commercial truck traffic at all hours, including tanker trucks, flatbeds, and refrigerated trailers serving the airport and surrounding distribution facilities. The interchange where 121 meets I-635 near Grapevine is one of the most complex in the region and has been the site of numerous truck accidents.

The Dallas North Tollway (DNT)

While the Dallas North Tollway sees fewer 18-wheelers than the interstates, commercial vehicle traffic has increased significantly as Frisco, Prosper, and Celina have grown. Box trucks, delivery vehicles, and commercial fleet vehicles are common on the DNT, and the high speeds on this tollway — with many drivers exceeding 80 mph — make any collision with a commercial vehicle devastating.

Interstate 30 (I-30)

I-30 running east-west through Dallas is a major commercial freight corridor carrying trucks to and from Arkansas and East Texas. The stretch through downtown Dallas, where I-30 intersects with I-35E and I-45, is one of the most congested interchanges in the state. Multiple lane changes, narrow shoulders, and aging infrastructure contribute to the high rate of truck crashes in this area.

What Makes These Roads So Dangerous for Truck Accidents

Several factors contribute to the high rate of truck crashes on DFW highways. Freight volume has increased due to the growth of e-commerce fulfillment centers throughout the region. Construction zones are constant on DFW highways, narrowing lanes and creating sudden traffic slowdowns that heavily loaded trucks cannot stop for in time. High speed differentials occur when 18-wheelers traveling 60 mph encounter passenger cars moving 75 to 80 mph, creating dangerous closing speeds during lane changes. Complex interchanges with multiple ramps and weaving zones force trucks to make lateral movements across multiple lanes in short distances.

Injured in a Truck Accident on a DFW Highway?

If you or a loved one was injured in a truck accident on any North Texas highway, the location of the crash matters for your case. Attorney Matthew Ford understands the specific hazards of DFW roads and uses accident reconstruction experts, traffic data, and the truck’s electronic data to build the strongest possible case.
