South Carolina does not require drivers to carry Uninsured Motorist (UM) coverage but you'd be wise to consider paying a little extra for it. According to a 2007 study by the Insurance Research Council, as many as 9% of the state's drivers are uninsured, and UM coverage is the only way to make sure you're protected if you're in an accident with one of those people. Major insurance companies have offices in Columbia, Charleston, Greenville, and Rock Hill.
