I recently got pulled over on my way into a University of California campus parking lot for not putting on my turn signal. The officer came to the window, smelled marijuana in the car and asked me to step out. He asked me if I had any in the car and I said yes. He asked me if I had been drinking and I said that I had been but much earlier and that I had sobered up. They did several field sobriety tests and had me blow through a breathalyzer. They found the marijuana I had, which was under 28.5 ounces, and my pipe. The breathalyzer showed that I had a 0.02 BAC. I am under age 21 but at least 18, so they wrote me a ticket for underage DUI of 0.02 and possession of marijuana under 28.5 grams. Both of them are misdemeanors. The officer sent me back to my friend's room on campus but not before taking my license and telling me that I had 45 days before the provisional ticket license he had given me expired. 35 days later, I got pulled over in California for speeding and the officer said that my license had been suspended. I explained that I didn't understand and he said that I had been allowed to drive for 30 days. I told him I didn't know that I couldn't drive because of what the other officer told me. He wrote me a ticket for speeding and for driving with a suspended license. My dad had to pick me up so the car wouldn't be impounded and I wouldn't go to jail. My dad told me that I could end up going to jail. I'm just a college student who made a few mistakes. Could someone please tell me a) what should my defense in court be? b) what are the minimum and maximum penalties? and c) what is the most likely result from the trial? My dad is a California police officer and knows protocol. He says that because the officers didn't ask me if I had burped or thrown up in the last 15 min before I took the breathalyzer test, the reading could be proven as unreliable. Also, I'm trying to get out of the suspended license charge because I was uninformed. I know it says it on the ticket, but because the officer told me 45 days I went with what he told me. I can't afford to talk to a lawyer and I know a public defender will just tell me to confess to everything. I'm worried about my record, my license, and possibly going to jail. Please respond as soon as possible because my court date is soon. Thank you.
