I received a ticket for careless driving in a parking lot at the University of Oklahoma. I was involved in an accident when pulling out of the parking aisle onto the road leading to the parking lot exit. I was t boned by a car that was driving to the exit, I didn't see this car because my vision had been obscured by large trucks parked at the end of the parking aisle (I drive a Honda Civic). It also seemed to me at least that the other car was speeding since the other driver didn't apply their brakes or sound their horn (also my airbags deployed). The other driver also received a careless driving ticket. The police officer did not witness the accident he arrived at the scene a few minutes later. I also question the legality of issuing a city ticket for careless driving in a private parking lot. I went to court today and plead not guilty, and have a trial set for the middle or january. What is the best way to prove my case?
