After a big rig accident: call 911, accept medical evaluation even if you feel fine, and photograph the scene including the truck's USDOT number. Collect witness details. Do not admit fault, do not give the trucking company's insurer a recorded statement, and contact a lawyer quickly — the truck's data can be overwritten within weeks.

What you do in the hours and days after a collision with a semi-truck has a real impact on both your health and your legal claim. Trucking companies and their insurers often have rapid-response investigators working the scene the same day. This guide levels the field.

At the scene (if you are physically able)

  1. Call 911. Get medical help for anyone injured and ensure police respond — the crash report matters.
  2. Accept medical evaluation. Adrenaline masks injuries; brain and internal injuries often present hours later.
  3. Photograph everything you safely can: all vehicles and their positions, the truck's DOT and MC numbers on the cab door, the license plates (tractor and trailer), skid marks, debris, road conditions, and your visible injuries.
  4. Get the driver's information — license, insurance, employer name — and note the trucking company on the cab.
  5. Collect witness names and phone numbers. Independent witnesses are gold and disappear fast.
  6. Say only what's necessary. Don't apologize or speculate about fault — those statements resurface later.

In the first week

  1. Follow through on medical care. Go to every appointment and follow treatment plans. Gaps in treatment are the first thing adjusters use to devalue claims.
  2. Request the police report (or note the report number and responding agency).
  3. Preserve your own evidence: keep damaged property, save dashcam footage, write down your memory of the crash while it's fresh, start a symptoms journal. If a tire failed, photograph every piece of tread — see truck tire blowout claims.
  4. Notify your own insurer of the accident — but stick to basic facts.
  5. Do not give a recorded statement to the trucking company's insurance adjuster, and don't sign medical releases or settlement papers. You are not required to, and early statements are routinely used against victims.

Why speed matters more than in a car accident

The most important evidence in a truck case belongs to the trucking company: the black box data, driver logs, inspection records, and dispatch communications described on our FMCSA regulations & evidence page. Some of it can be legally destroyed within months — some overwritten within weeks. A big rig truck accident lawyer sends a preservation letter immediately and, in serious cases, gets an accident reconstruction expert to the vehicle before it's repaired.

Watch for these insurer tactics

Unopened settlement envelope and a medical release form slid across a table toward a person
  • The fast, friendly settlement call — an early offer made before your injuries are fully diagnosed
  • The recorded statement request — framed as routine, used to lock in damaging phrasing
  • The blanket medical release — gives access to your entire medical history to hunt for "pre-existing conditions"
  • Delay — waiting out mounting bills to pressure a low acceptance

Deadlines apply

Every state sets a statute of limitations for injury claims — commonly one to four years, with far shorter notice periods if a government entity is involved. Waiting costs leverage even when it doesn't cost the claim. Learn who can be held liable and what compensation may cover, or find out where you stand in 60 seconds with a free case review.
