San Antonio Semi-Truck Accident Attorneys: What You Need to Know Before You Call Anyone Else
A semi-truck — also called a tractor-trailer, 18-wheeler, or big rig — is a combination vehicle consisting of a Class 8 tractor pulling one or more trailers, with a gross vehicle weight rating (GVWR) up to 80,000 pounds under federal law. When a fully loaded semi-truck strikes a passenger vehicle on IH-35 or IH-10, the physics are not comparable to a car accident. The kinetic energy difference is catastrophic. Survivors frequently sustain traumatic brain injuries, spinal cord damage, crush injuries, amputations, and internal organ trauma that require lifetime medical care and permanently alter earning capacity.
San Antonio is one of the highest-density semi-truck corridors in the United States. IH-35 is the primary NAFTA trade route connecting Mexico to the Midwest — more than 7,000 commercial trucks pass through the San Antonio metro daily. IH-10 carries high-volume freight between El Paso, Houston, and the port cities. Loop 410 and Loop 1604 concentrate commercial traffic around the metro, and US-281 and US-90 serve construction and industrial freight. Every major arterial in Bexar County carries semi-truck traffic, and the crash rates reflect it.
Wayne Wright LLP has represented semi-truck accident victims throughout San Antonio and Bexar County for nearly three decades. Our attorneys understand what separates a well-built tractor-trailer case from one that settles for a fraction of its value: immediate evidence preservation, FMCSA regulatory expertise, and the credibility that comes from taking cases to trial. Partner Wyatt Wright is a former Bexar County police officer with a Master Peace Officer certification — he has investigated commercial vehicle crashes from both sides of the law, and that background is directly applied to every semi-truck case we handle.

When Wayne Wright is retained for a semi-truck accident, the first 24 hours are critical: we issue spoliation letters to the carrier, subpoena the Electronic Data Recorder (black box) before data overwrites, demand ELD logs documenting every hour the driver was on duty, request dashcam and forward-facing camera footage, and identify every party with liability exposure — the driver, the motor carrier, the cargo shipper, the maintenance contractor, and the vehicle or component manufacturer. The major semi-truck insurers — Old Republic National Transportation Insurance, Great West Casualty, Protective Insurance, and Progressive Commercial — deploy field investigators within hours of a serious crash. Wayne Wright deploys attorneys within the same window.
The carriers operating the highest-volume routes through San Antonio include national fleets with dedicated Texas operations: Werner Enterprises operates thousands of dry van and temperature-controlled routes on IH-35 and IH-10 and regularly hires drivers in San Antonio; J.B. Hunt Transport, with a San Antonio terminal at 10809 Sentinel Street, is one of the largest dedicated contract carriers in the country; Knight-Swift Transportation, Schneider National, and CRST International all maintain active Texas operations through the IH-35 NAFTA corridor. Regional carriers including Parkway Transport (DOT 212550), based in San Antonio, operate hazmat and refrigerated routes throughout Bexar County. When any of these fleets is involved in a serious crash, their insurer activates an institutional response system that begins before the injured person has left the hospital. Wayne Wright activates on the same timeline. Get your free case evaluation today →
