Former resident here who traveled I-77 frequently. I strongly warn all drivers, especially out of staters, to be very careful when traveling (north AND south) on Interstate 77 in Carroll County near the town of Hillsville. County deputies are almost always out aggressively enforcing traffic laws. I-77 is a high priority to the county due to the easy revenue it brings. Most people don’t challenge the tickets because they are not local. The county depends on that. Sometimes state police and local Hillsville town police are also present, who have a short strip of I-77 to enforce. I strongly encourage everyone to record your encounter if you are pulled over. You will still get a ticket of course, but it will keep their professionalism in check. Be polite but have that camera rolling. Take it easy on I-77 until at least you get out of the county.
