You're driving on a road with only one lane in your direction. You see an emergency vehicle stopped ahead with its flashing lights on. What should you do?

Under South Carolina's Move Over law, to pass an emergency vehicle that is stopped with its lights flashing, you must slow down. You must also move into a non-adjacent lane if possible, leaving at least one vacant lane between you and the emergency vehicle. (Note 1: The South Carolina Driver's Manual implies that you only have to slow down if you cannot move into a non-adjacent lane. But the text of the law states that you must slow down whether or not you move into a non-adjacent lane. Note 2: All US states now have their own Move Over laws, but some of them require drivers to do different things. When traveling out of state, always check the local traffic laws.)
