I got a 100 dollar ticket for improper driving on a mountain road because I started fishtailing due to slick roads and I hit the guard rail. Didn't hit anyone else and I was going with the flow of traffic. Roads didn't look slick. Can I fight this?

Yes, you can fight it, and you may get it waived or reduced. You probably won't for exactly the reasons Jack mentioned, but you do have a chance as you fishtailed due to non-visible ice.

No, you can't fight it because you were at fault -- really. (five driving schools have taught me this). You were going too fast for conditions. According to the law, the posted speed limit is the speed limit for *ideal* conditions. Ideal conditions are: dry pavement, 100% visibility, no impeding traffic, good road surface (as in no ice or loose gravel), no sun in your eyes, vehicle in top condition, etc. Anytime you get the cops involved, it costs the state / local enforcement departments money; therefore they are going to fine you. The fact that you were 'going with the flow' doesn't matter because technically you were going too fast for conditions, and the fact that others were as well has nothing to do with *your* particular case.

You can fight it if you want The cause of the accident was excessive speed for road conditions. So if you were going with the flow how come no one else was fishtailing?

The law states that you are to have your vehicle under control at all times. Apparently, you did not. You drive, according to the weather and road conditions. you knew or should have known about the possibility of a slick pavement. was it raining? In any event, you hit a gurardrail. was the guardrail damaged? Sounds to me like the officer did his job, when issuing you a citation for improper driving. Go to defensive driving class or pay the fine.
