Unsafe backing? Idaho

I am a tow truck driver in Idaho. I had to return to a call for contact information. I pulled into a driveway to back out on a two lane road made sure road was clear etc. I was done backing out and was straighting out my wheels heading west bound when a car came flying east bound. She saw me locked up her wheels, started swerving and hit back end of my truck in West bound lane. I got cited for unsafe backing but when she hit me I was no longer backing and was in my lane. I'm nervous about losing my job and being held at fault. Her husband then showed up after she hit me and was screaming acting a fool so I waited in the truck until state police came. They took my statement then gave me a citation. I'm going to fight the citation I don't personally believe I'm at fault she came into my lane. My truck was also hit by a drunk driver parked in front of my house about 4 months ago. I have only been driving truck for roughly 6 months. Am I in the wrong? Am I going to be fired? Should I fight the ticket or should I just pay it? This happened in Idaho.

 

She was swerving because of her breaks being locked up and her freaking out. My best guess is she caught and shot underneath me. Or she finally let off the breaks and had her wheel turned my way. They said I was at fault because I had backed up a minute prior. I was in drive when she hit.

 

I'm not sure if there would be skid marks the road was freshly plowed and cops let traffic through. The road was starting to turn into slush. I'm more nervous about my job then anything. My boss told me because I got a citation I was at fault for the accident.

 

I'm going to thank you. When the lady's husband showed up he asked "who is the ########## who hit my wife" I told him I was the ########## and she hit me she had told him I was in the middle of the road
