I was driving very carefully on an interstate in Washington state where the speed limit is 60mph. I hit some black ice when I was going about 40mph, and it caused my car to slide back and forth within my lane and eventually spin around 180 degrees. The traffic was light, but the car that was originally behind me in the same lane ended up sliding into me head on because they couldn't stop either. The trooper never told me I was getting a ticket, but then I got one in the mail for speeding too fast for the weather conditions. Should I just pay the ticket, or is it worth contesting in court? Are there any other options (heard something about deferred)? Any information is appreciated.
