7 Critical Steps After a Dallas Truck Accident — What Injury Victims Need to Know

After an 18-wheeler collision, your first responsibility is to get out of harm's way. Move your vehicle if safe and possible to do so. If you're injured or the vehicle is not movable, stay put and activate hazard lights. Call 911 immediately—Dallas Fire-Rescue dispatches both EMS and law enforcement to the scene. The driver's condition matters legally: if the truck driver is impaired, a drug screen ordered at the scene becomes discoverable evidence. Do not leave the scene until police release you. A hit-and-run, even if the truck is damaged and identifiable, complicates the claim significantly. If you can safely do so while waiting for emergency responders, note the weather conditions, the position of all vehicles, any visible cargo spillage, and whether the truck's lights were functioning. These details corroborate later expert testimony about the crash dynamics.

Contact Dallas Police Department (non-emergency: 311 or 911 for emergencies) immediately. A police crash report is essential. Request that the responding officer document: the commercial vehicle's DOT number (visible on the cab door), the driver's commercial driver's license classification, and whether a commercial inspection was initiated. The CSA score of the motor carrier is public information at FMCSA.dot.gov—a high unsafe-driving CSA score predisposes negligence claims. Ask the officer to note any visible driver fatigue, vehicle damage inconsistent with speed, or regulatory violations (improper placarding, overloading). In Dallas County, crash reports are filed with the Dallas Police Department accident investigation bureau. Request the case number and the officer's name for your attorney. The report becomes the foundation document for your claim. Don't assume the insurance adjuster will obtain a complete report—your attorney needs the original, unredacted version.

Commercial truck accidents leave multiple types of evidence. Photograph the entire scene from multiple angles: the damage patterns on both vehicles, the road surface conditions, any skid marks, debris field, street names and intersections, traffic signals, and weather conditions. If you're injured but able, use your phone. If not, ask witnesses to help or wait for emergency responders to document. Critical evidence in commercial truck cases includes: (1) the truck's cargo information—overloading increases rollover risk; (2) the driver's pre-crash behavior (any swerving, speeding, erratic lane changes witnessed by others); (3) the truck's mechanical condition—any visible defects, leaking fluids, or blown-out tires. Do not touch or move evidence. The Electronic Logging Device (ELD) in the truck cab records speed, braking, and hours of service in real-time. This data must be preserved immediately through a preservation letter sent by your attorney to the motor carrier. Many states, including Texas, require preservation within 15 days.

Witnesses are critical in commercial truck accident cases, especially if the crash happened on a major Dallas corridor like I-35E or I-45, where multiple vehicles may have witnessed the collision. Get names, phone numbers, email addresses, and a brief statement from any witnesses willing to provide one at the scene. Ask specifically: Did you see the truck before the collision? Was the driver swerving or braking hard? Did the truck's brakes fail visibly? Did the driver appear alert? Document all witness statements in writing immediately; memory fades within days. Also request dash camera footage from nearby vehicles. In busy Dallas traffic, several drivers may have recorded the collision. If this happened near a commercial area, nearby businesses may have surveillance cameras. Your attorney will send formal preservation and discovery requests for this footage, but noting witness names and potential camera locations at the scene accelerates the process. Dash camera footage often captures the seconds leading up to impact, which expert reconstructionists need for liability analysis.

Do not refuse transport to a hospital. Even injuries that feel minor can be catastrophic in high-speed commercial vehicle collisions. Parkland Memorial Hospital and UT Southwestern Medical Center in Dallas are both Level 1 trauma centers equipped to handle the severe injuries common in 18-wheeler crashes. A complete medical documentation at the trauma center creates the medical foundation for your claim. The hospital records the type and severity of injuries, imaging (X-rays, CT scans), and treatment, all of which correlate directly to settlement value. Additionally, a post-crash drug screen ordered by law enforcement on the truck driver is a critical piece of discovery. It must be preserved and obtained through your attorney. Medical records must be obtained within 30 days of treatment; after that, many hospitals charge high record-retrieval fees. Store copies of all emergency room records, discharge summaries, and physician notes securely. These documents are not discoverable by the motor carrier until your attorney decides to share them, so keep them confidential.

Within 24–48 hours, the truck driver's liability insurance adjuster will contact you. They may seem friendly and helpful. They are not. Their job is to minimize the insurer's liability. Any statement you give—recorded or unrecorded—can be used against you later. You are not required to give a recorded statement. In fact, you should not. Texas law permits you to decline. Instead, respond with: "I'm not giving any statement until I've consulted with an attorney." Then hang up. The adjuster will warn you that declining a statement "looks bad" or "prolongs the process." Neither is true. A short, unguarded statement to an adjuster can sink a claim worth hundreds of thousands of dollars. The trucking company's lawyers will use every word. An attorney experienced in commercial motor vehicle claims will know what questions to anticipate and how to frame your statement if it becomes necessary. Your attorney will direct all communication with the insurance company. This is not negotiable in complex commercial cases.

The single most critical step you can take in the first 72 hours is to have your attorney send a preservation letter to the motor carrier and any involved insurance company. Texas requires carriers to preserve evidence relevant to the claim. The preservation letter formally puts them on notice and starts a legal duty to retain: (1) the driver's ELD data and backup server records; (2) the driver's qualification file and DOT medical certificate; (3) dispatch records, communications, and trip logs for the date of the accident; (4) the truck's maintenance records for the prior 12 months; (5) onboard camera footage if the truck is equipped with one; (6) post-crash vehicle inspection reports. If the motor carrier deletes or fails to preserve this evidence after receiving your preservation letter, they face spoliation penalties and adverse inference instructions at trial (the judge can tell a jury to assume the destroyed evidence would have proven your case). An experienced Dallas truck accident attorney knows exactly what to demand. Waiting to send this letter—even by a few days—can result in the loss of irreplaceable electronic data.
