South Carolina is a member of the Drivers License Compact (DLC) which requires member states to exchange information regarding tickets motorist receive out of state back to the state in which the person is licensed. Tennessee dropped out of the DLC in 1997 so is not currently a member of the agreement but the state still reports tickets back to your home state and other states can still report moving violations to the TN Department of Safety.

Once the South Carolina Department of Motor Vehicles (DMV) is informed of the Tennessee speeding citation, the South Carolina Motor Vehicle Code allows for out of state violation convictions to be recorded against your SC driver's license if the violation matches up to a violation in South Carolina. Speeding of course does match up with as a traffic offense in SC.

You will need to contact the SC DMV to find out whether points will be assessed for the TN speeding ticket. If points are assigned, it would appear it would be 4 according to the SC violation points list of speeding more than 10 mph but less than 25 mph over the posted limit.

Once the conviction makes it onto your SC driving record, then your insurance rates could be affected when your insurance company sees the violation on your MVR. If you believe this traffic infraction will cause your rates to rise, to stop an increase you may want to check with TN and see if there is a way in which to get the ticket dismissed so that the ticket is not reported back to SC.

Check with your insurance provider about their rating system to see if this traffic ticket will affect your rates or not. The South Carolina Department of Insurance can also give you information on your insurance company's rating system since rates must be filed with this state agency.
