What happens if a police officer charges you with the wrong crime?

I was pulled over for backing down a street and the officer gave me a charge for improper driving on laned roadway. I looked it up and it says nothing about how you are driving you car just as long as you stay in your lane. I did however find a charge for illegal backing and it says that you maynot back up unless it is safe and you are not stoping traffic. I wasent stopping traffic and i wasent going very fast maybe 10 miles per hour and there was no pedestrians. Do you think i could win in court for him giving me the wrong charge or not?
