I was driving down a back-road during a very heavy rain. While coming around a corner my car hydroplaned and went straight instead of being able to take the turn. The car went down a short embankment and through a wooden fence. There were no other cars involved and no injuries. A police officer arrived at the scene and cited me for failure to maintain lane.
I was not speeding, but conditions were wet and it was raining very hard. I know the code states that I must maintain lane "as nearly as practicable". Do the weather conditions give me any defense in this case?
