Alcohol & Drugs: MIP, MIC, Intoxication MIP in Washington state

[ahab]

I'll turn eighteen in one month and here's what I'm looking at. I was pulled over on my bike for having a six pack (this might sound stupid but I uh, thought you had to be doing something illegal to get pulled over outside of 'looking too young') and the officer charged me with an MIP, read my rights, and dropped me off at my house. I DID recieve an MIP about 4 months ago, but I was never prosecuted for the offense and got off the hook. Really the only thing I'm nervous about is that I'm supposed to leave for Arizona in 4 weeks to start college. I'd be fine with a fine or a suspended license w/e but how is this going to affect my starting college on time? Thanks in advance for your input.
