Crash-scene and identifying information
Start with information that identifies the collision and the people or agencies involved.
Police and emergency recordings
Retention practices vary. Identify the record precisely and make requests promptly.
Intoxication-investigation evidence
Availability and admissibility depend on the investigation, applicable law, and the individual case.
Possible alcohol-provider evidence
This category may matter only when the facts support investigation of a bar, restaurant, event venue, or other provider.
Injury and financial-loss documentation
Consistent records help explain what changed after the collision.
Request and preservation log
A checklist is not a preservation letter, subpoena, or legal deadline calculation.
Important limitations
This general checklist is not legal advice and does not create an attorney-client relationship. It cannot identify every evidence source, retention period, preservation duty, filing deadline, or objection in a particular case. Texas Settlement Calculator is not a law firm or government agency. Do not delay emergency care or case-specific legal advice because of this checklist.
Primary sources and further help
