I don't often agree with the ACLU, but on some issues our interests align perfectly.

Here, from their website, is a downloadable PDF file formatted for easy printing. The document summarizes a citizen's rights when interacting with officers, and offers hints on how to safely comply with lawful police instructions without unwittingly giving up those rights.

The guide apparently was created to fight the phenomenon of "driving while black", but is broad enough to be useful as a general guide for most cop-citizen encounters.

Educate yourself.
