South Carolina mandates that resident drivers carry minimum auto insurance to operate vehicles on public roadways. These rules exist to ensure that the state’s roads and highways are as safe as possible, though they should not be construed as recommendations. Only you can assess your car insurance needs to determine whether additional coverage beyond the minimums is right for you. Online services that compare car insurance quotes can be valuable in helping ensure that you find a low cost car insurance policy once you have defined your necessary coverage.
