We have a "work" softball team (it is made up of all people who I work with but the company doesn't sponsor it although we do have the same team name as our company name). I got a ride from one of my coworkers so I could have a few beers at the game. I made a poor choice because the coworker had been drinking a bit before he picked me up and had a few more beers through the game. On the way home, he got pulled over and blew over the legal limit (0.08 BAC). I was also breathalyzed, but I only blew a 0.06. I was allowed to call for a ride and leave, but the car was towed and my coworker was taken to jail for DUI ("Driving Under the Influence").
Moving past the terrible decision I made in allowing myself to ride with an intoxicated person (I was aware there was booze involved, trusted that that amount was safe), what are my obligations to my company here? Do I have to report this to my bosses? The coworker and I share department leads. I didn't get in any legal trouble here so it feels like I should be in the clear. If I don't tell my bosses am I opening myself up to repercussions?

UPDATE: My coworker told my company, and said I was with him. Now I'm supposed to meet with HR tomorrow morning.
