Backed into a parked car and drove away. jail time in my future?

I have 2 at fault accidents prior. And I have a marijuana arrest in 2011. I backed into parked car in a parking lot and left because of nervousness and stupidity. The damages were close to none. Bystanders caught my tag numbers and reported it in. A few days later cops were at my house while I was at work looking for my car. So, I called up the police headquarters and met with the responding officer at the place if accident. I got 3 charges for hit and run and a payable fine for not having my insurance card. I met with the commissioner today to review my charges and said that they are 2 months $500 each. I have a lawyer that I haven't spoken to yet. Do I see jail time in my future or will there be any possibility of probation?
