Dad, scares me so much Options

I don't know if this is in the right place, I just don't really know what to do when this happens, and I searched, but found nothing that answered my question.

Here goes...

My dad and my mom have been fighting for as long as I can remember... my earliest memory was of my sister and me confronting them when I was about four... I know it sounds like a normal case of fighting parents, but it has really bad points to it.

I heard from my sister (she's now 24... I'm 13.) that she went through alot before I was born, and that I shouldn't be complaining, because my dad always used to get arrested when she was little. But I think my situation is worse, she just doesn't realize it.

The first time my Dad went all-out crazy was in the morning, when he and my mom were arguing about something stupid- like the way the pancakes looked or something idiotic like that. He drove my mom to the edge and she laughed like crazy when she just hit him in the face (not hard) with a green scrubby. He got really mad- and he slapped her.

I thought that was the end of it, because my mom told me that after she got her surgery on her knees done, she would divorce my dad.

But just yesterday, in the car, my Dad got into a fight on the road with some guy who was pissed that my Dad was driving so fast that he stopped suddenly and almost made us have a wreck- most of the fight was my fathers' fault, but my Mom just freaked out so much that my Dad went nuts again and nearly slapped her on the arm, yelling about how she was stupid for sitting in her seat, yelling about how to stop.

My mom was so mad, we were going to leave, but I was scared that my Dad would do something crazy if he got mad, so we stayed.

After that, I felt very scared that something was going to happen, and I was stuck trying to make a hard choice...

- I could stay at home, scared to death.
- I could leave with my mom, risking my dad getting mad and doing something outrageous.
- I could call my sister and beg her to come over, risking her yelling at my Dad and making things worse.
- I could go over to my best friends' house, who lives right behind me, and stay there until I felt it was safe, leaving my parents alone together.

I ended up staying there, but I was so freaked out until my Dad left and came back hours later.

I'm nervous about posting this on the internet, because I don't want people to find out and report us or something, and I guess I just needed to rant, but just in case this happens again:

Which option should I do, even with the risks? And do you have any other suggestions that could help me if a problem like this comes up again?
