Direct Answer Under Texas Law

Every occupant listed on Page 1 of a Texas Peace Officer's Crash Report (Form CR-3) is assigned a single-letter KABCO Injury Severity Code by the investigating officer: K = Fatal Injury (death within 30 days); A = Suspected Serious Injury (incapacitating injury preventing walking/driving away); B = Suspected Minor Injury (visible laceration, bruise, abrasion, or limping); C = Possible Injury (complaint of neck/back pain or nausea without visible wounds); and N = Not Injured.

Critical Texas Procedural Trap to Watch Out For

If you tell the officer at the roadside 'I'm shaken up, I think I'm okay' and decline EMS checkup, the officer enters Code 'N' (Not Injured)—which insurance software (Colossus) later cites to argue you were uninjured at the scene.

Recommended Action Plan for Texas Claimants

If you feel any neck tightness, headache, dizziness, or back pain at the crash scene, tell the investigating officer immediately so your CR-3 is coded 'C' or 'B' rather than 'N', and follow up with a physician within 24–48 hours.

Code Ch. 55 & Ins. Code Ch. 140).
