I pass by trucker's that are pulled over by public service all the time. I have my scanner programed for the D.O.T. but I do not receive any communication from them. I can not see a listing for Public Service in the WV data base. So, is there any information I am over looking or are these frequencies not listed. I have looked on the WV trunk system's and conventional. I have the entire D.O.T. system for WV programed in. Can any one help me?
