Reckless Driving Ticket which I do not consider my fault and wants to defend.

Hi, I am from jersey city, new Jersey and I am Nurse. It was two days after hurricane sandy and there was a chaos everywhere, roads were closed, no power and still I had to go to work. So, it was evening and I was returning home. All small roads were closed by police, barricades everywhere to keep traffic moving only on main roads. I couldn't find any open roads that I know to take turn and go home. After driving a mile away from my actual turning point I decided to ask a cop to show me any open road to way back home. It was a slow moving a traffic and I see a cop's car behind a barricade. I took my car to side of that barricade so that traffic keeps moving and stopped in front of barricade to ask cop way back home. Before even I speak anything that fat shit lady cop came out from car shouting out loud "I am gonna give you reckless driving ticket." I was literally shocked by such behavior. At such time in state of emergency I was expecting cop to be helpful not to be so rude.
