My question involves criminal law for the state of California
On the day of my grandfather's funeral, some relatives and I had some drinks at the reception. Later that night on my way back home I stopped to get gas. As I pulled out of the station, I had driven less than about 100 feet and I got pulled over because I forgot to turn my headlights on. The officer apparently smelled the alcohol from me and proceeded to administer the field sobriety test. I performed each task pretty well and was confident I was fine so I conceded to the breathalyzer test. I blew a 0.08 exactly so I was taken away.
At the station the formal breathalyzer test showed 0.07. After all the processing, the officer told me he was going to cut me a huge break. He said they're not going to take me to jail and instead let me go home as long as I have someone to pick me up. He also said he's going to write it off as an error. As he escorted me to the door he told me that I didn't do bad at all on my FST and had I not blown into the breathalyzer, he probably would've let me go at the scene.
To add to the story, a few days ago I got a letter from the DMV stating they reviewed my case. The letter explained how my suspension was set aside allowing me to apply for a duplicate license with no fee at all.
This is where I'm confused. I couldn't find anyone with the same experience as me to ask for advice. What exactly does this mean for my case? Money is extremely tight for me right now so do I still need to hire a private attorney? Any help would be much appreciated.
