The moments after a semi-truck accident are chaotic and traumatic. But the decisions you make in the first hours and days can profoundly affect your ability to recover full compensation. Trucking companies respond to crashes with immediate tactical precision — you need to as well.
This guide walks you through exactly what to do after a commercial truck accident, from the crash scene to retaining legal counsel — in the order that matters most for protecting your claim.
At the Scene (First 30 Minutes)
Step 1: Call 911 immediately. Even if injuries seem minor, request law enforcement and emergency medical services. An official police report is foundational evidence. Do not let the truck driver persuade you to handle it informally — trucking companies use that leverage later.
Step 2: Seek medical evaluation on-scene. Accept paramedic evaluation even if you feel okay. Many serious injuries — traumatic brain injuries, internal bleeding, spinal damage — present with delayed symptoms. Refusing care at the scene can be used by insurers to argue your injuries weren't severe.
Step 3: Document everything you can. If you're physically able, use your phone to photograph the truck (license plate, DOT number on the door, company name), the damage to your vehicle, the accident scene including skid marks and debris, road conditions, traffic signals, and any visible injuries. Capture video if possible — a 360-degree walkthrough of the scene is invaluable.
Step 4: Get witness information. Collect names, phone numbers, and email addresses from anyone who saw the crash. Witnesses often leave quickly, and their accounts can be critical when the truck driver disputes liability.
Step 5: Do not speak substantively to the truck driver or their employer. Exchange insurance and identification information, but do not discuss fault, apologize, or explain what happened beyond what's necessary. Anything you say can and will be used against you.
Within 24 Hours
Step 6: Get a thorough medical evaluation. Go to an emergency room or urgent care center, even if the scene paramedics cleared you. Request full documentation of all complaints. The connection between the accident and your injuries must be established in medical records from the earliest possible date.
Step 7: Preserve your own evidence. Save all clothing you were wearing (do not wash it). Photograph your injuries every day as they evolve. Keep a daily pain journal documenting your symptoms, limitations, and emotional state. This documentation is invaluable for pain and suffering calculations later.
Step 8: Contact a truck accident attorney. This is not premature — it's essential. The trucking company's legal team is likely already working on the case. An attorney can send spoliation letters immediately to preserve critical evidence.
Within 72 Hours — The Black Box Window
Step 9: Demand preservation of the truck's Electronic Data Recorder (EDR). Modern commercial trucks record pre-crash speed, braking data, throttle position, GPS location, and engine performance in the seconds before impact. Many systems overwrite data after as few as 30 days — or sooner if the truck is involved in another incident. Your attorney must send a legal preservation letter (spoliation notice) within days.
Step 10: Don't sign anything from the trucking company's insurer. Insurance adjusters may contact you quickly with a settlement offer. No matter how tempting, do not accept or sign anything until you've consulted an attorney. Early offers are almost always a fraction of what the case is worth.
In the Days Following
Follow all medical treatment recommendations without gaps in care — gaps are used by insurers to argue your injuries healed. Keep every medical bill and receipt. Notify your own auto insurer of the accident. And let your attorney handle all communication with the trucking company and their insurer. The 72-hour window after a truck accident is when evidence is most vulnerable — and most powerful. Act quickly to protect it.
