SC DOT uses VHF Low-band repeaters in each county as their primary communication system. Most crews working to maintain Interstate highways and state roadways will use the repeater assigned to their county.
SC DOT also has assigned talkgroups on the Palmetto 800 system. Operations traffic on Palmetto 800 is very limited.
SC DOT also operates the State Highway Emergency Patrol (SHEP). These are vehicles and trained operators that patrol interstate highways and assist stranded motorists and traffic control around accident scenes. Their primary operations are on the "DPS" talkgroups listed under each SCHP Patrol troop talkgroup category. They also have secondard operations/talk-around talkgroups listed.
