You are driving in the right lane of a four-lane highway. You see an emergency vehicle stopped ahead with its lights flashing. What should you do?

Under Ohio's Move Over law, to pass an emergency vehicle or a public safety vehicle that is stopped with flashing lights, you must move into a non-adjacent lane if possible, leaving at least one vacant lane between you and the emergency vehicle. If this is impossible (because there are no other lanes in your direction) or unsafe, you must slow down. (Note 1: The Digest of Ohio Motor Vehicle Laws states incorrectly 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.)
