That is something that our CHART trucks can not do here in MD and they have a mix of Red and amber in the front and rear when running code having to make their way thru traffic. I can see both sides of the coin about SSP being encrypted but then again are they using a MDT when they run a tag or call it in ? here CHART calls in the tag number to TOC which is located in Jessup ,MD on the south side of KBWI across the street from it and even if they are in Fredrick or western MD they still talk to TOC 50 or more miles away. Not sure when they over on the eastern shore across the bay but that is District 1 for the CHART trucks and they do patrol over along Rt 50 between the Bay Bridge and Ocean City and they can also come up on the MSP different Talk Groups as well.
