Leaving the scene of an minor accident. What to expect at court?

So pretty much got into a minor accident while i was unisured.
I was coming from the library on a rainy day cause i had to go be home to wait for my little brother to get off the bus. But when i was on my way home, I was driving up the road and a green van that was stopped quickly switch to the right lane, had me end up hydroplaning into another person silver 98 ford car just giving my hood a lil dent and righthead cover cracked. I couldnt stop the car enough in time. So i end up rearing them, Everything was minor. My first accident, Never had a record, had insurance when i first got the car, couldnt keep up with the payment so i let my car lapse cause i was switching insurance and my insurance don't take full effect on a thursday. But i end up panicking, scared and i had to get home before my bother bus come within 8 mins, also to mention this happen two block away from my house on the road, So i end up leaving scene having no knowledge i wasn't suppose to leave until the cop came around my house 7 min later after bother got off the bus and my mom pick him up after coming off from work. The officer ask me if was "Blah blah" i answer politely and did exactly what i was told, i show him my ID and registration. Gave my honest to the cop, he respect my honesty. But the other cop the investigating officer came and i ask me what happen. I told him aswell, i got arrested. Got to show up to court in two weeks for PTA. What am i suppose to expect? My first offense?

Probably a stiff fine and a license suspension.

But, look: You have to focus. There's so much unnecessary detail in your story that it's not even funny. From the court's perspective:

You were driving home to meet your little brother at the bus stop. It was raining. You changed lanes and hydroplaned into the rear of another car. You were uninsured. You left the scene of the accident. The police located you. You admitted you were involved in the accident and left the scene.

That's it. That's your entire story in three lines. None of that other stuff matters. As you go through life, remember it's the facts that count.
