Many people are so stunned and hurt at the scene of a bike crash that they forget to collect basic information that will help them later. Dazed, they do what seems to make the most sense at the time—only to realize later that they forgot to collect vital information that they need to resolve matters.

The best way to avoid this problem is to know in advance what to do. I honestly hope you never need the information in this post. But I want you prepared, just in case.
