How would you fight this traffic ticket?
I got this ticket in February this year for failing to yield from private drive. I was leaving the parking area at school to cross the main street, with 1 lane in each direction. As I approached the intersection I was going to stop to check the traffic in both ways. I saw the vehicle coming from the left so I pushed the brake but couldn't stop. There was ice under the snow and my vehicle slipped and pulled right in front of that other vehicle. I caused an accident and got a ticket. The road conditions were terrible on that day, because there was an ongoing snow storm for several hours and the roads were not cleaned yet.
I am fighting this ticket, I am doing a trial.
How can I prove I am not guilty?
