In South Carolina, you may make a left turn at a red light if you are turning

In South Carolina, you can turn left on a red light when you are turning from a one-way street onto another one-way street, unless signs prohibit it. You must still come to a complete stop and yield to all pedestrians and traffic before you turn. Note: The laws on this are different in some other states. A few states (e.g., Michigan) also allow you to turn left on red from a two-way street onto a one-way street. Some other states (e.g., North Carolina) prohibit left turns on red altogether. When traveling out of state, always check the local traffic laws.
