Am I going to have to go to court?

I’m a 19 year old girl and I never get in trouble with police EVER, so I don’t know the rules or what anything means.

Tonight was a very rainy night, and my friend and I were on our way to the movies, when I saw two cop cars up ahead. Of course I slowed down to maybe about 25 since it looked like someone just got pulled over, and no one was blocking the street, and out of nowhere a cop who was directing traffic ( there had been a minor accident, but you couldn’t really tell, and there weren’t any other cars there at the moment) popped out of nowhere, I didn’t see him at all, and I slammed on my brakes and hydroplaned which caused me to almost hit him (but it wasn’t really THAT close of a call). I then stopped and the one other cop asked to pull over, and was very gentle. Then the cop who I didn’t see came over, yelled at me, and told me he should throw my a$$ in jail and walked away. The other cop then said that since they were busy with the accident that if the officer decided to give me a “summons for not obeying officer” I would get it in the mail. How long does that take?

I have to wait to see if he’s going to do something, but what would happen? Doesn’t a summons mean like suing? Am I going to have to appear in court, or am I just going to have to pay a ticket? I really don’t know! The guy was pretty angry, REALLY ANGRY at me and rightfully so, but I wasn’t driving recklessly, or speeding, I just hydroplaned on a very rainy night and couldn’t see. What is the worst that will happen to me?
