Most of what makes a claim go smoothly gets settled in the first sixty minutes after something happens, often by a person who is shaken and relying on memory. Car Insure Assist is written for that hour, and for the calmer stretch before it, while there is still room to prepare.
The guidance is checklist-shaped on purpose. One instruction at a time, the most important first, no warm-up. From there the site follows the claim forward: how an adjuster arrives at a figure, what actual cash value means, and which evidence really shifts a valuation.
Treat all of it as background on how US claims usually go. It is not advice about your particular policy, claim or situation. Terms of cover, the rules of each program and the legal requirements differ with every insurer and state and are updated now and then, so before you rely on any point that matters, confirm it with your insurer or the regulator that oversees it.
