My question involves a traffic ticket from the state of: Iowa
Do I have a case if the GPS speed limit differs from what appears on a photo speeding ticket? In my case, I was in an area of 25mph zone at the end if a downtown area, entering an area outside downtown with wooded areas on my sides, my GPS speed limit shows a change from 25 to 35 mph, and there are no other speed limit signs for over a 1/4 mile at least. After about a 1/2 mile, you return to a posted 25 mph limit. I received a ticket for doing 36 in a 25mph. I was well before the next speed limit sign which is where it went into a stoplight area- and past the stop light there was another 25 mph sign. I do not believe I was in a 25 mph zone where the address was stated in the ticket. Should I contest?

Thank You
