Crash evidence
Most of what proves what happened in a crash disappears on its own within days: loop recordings, store cameras, witnesses' memories. These guides and state pages cover what to save, who to ask, and what the law in your state lets you get, checked against the statutes and the agencies' own pages.
By state
Two pages per state: how to get the police crash report, and how to get police, traffic camera and other public video. Each is researched from the state's own law and agencies, then checked by an independent fact-check before it is published.
