I went on one not to long ago and I'm working on another right now as we speak....when I went I wore a black tactical polo, brown, BDU's, and tactical boots. I wore a flashlight, cell phone, my portable radio, all the stuff you really need besides weapons...my ride along officer let me get out of the car and confront people with her...so ask questions such as, "When we're on a traffic stop, would you like for me to stay in the car or get out to take notes or what?" and ask that same question about when you're on the scene of an MVA or any other call for that matter....it's up to the officer himself to let you do those things. So just ask politely and respect their decision no matter what it is. You'll have a great time! I did.
