Carpool/HOV Violation

[rlism]

I live off an expressway which has a carpool lane as the far right lane. This is the same lane as the merging on and off the expressway. I received a carpool violation after crossing the intersection following my merge, about 1600ft after my merge, probably 1000 ft after the carpool lane sign (I'll have to go back to check this).

I tried to plead my case to the officer but he stated there was ample time and space to move into the lane. There was almost no traffic except one vehicle in the adjacent lane. Is there anything I can/should do to contest this ticket?

Thanks in advance.
