The UHF channels on the Turnpike are still active only for the service vehicles and service plazas. I have not heard any toll plazas in sometime. They were on it before.
FHP has no UHF capability in their cars anywhere. They are stuck using their super duper Tyco, Ma-Comm, Critical Communications, Erricson, GE toaster system.
Well at least a toaster usually makes good toast!
