You are driving on a four-lane road. You see an emergency vehicle stopped ahead with its flashing lights on. What should you do?

Under Oregon's Move Over law, to pass an emergency vehicle that is stopped with its lights flashing, 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 or unsafe, you must slow down to a speed no greater than 5 mph below the speed limit. Note 1: Effective January 1, 2018, this rule was expanded to also apply to any motor vehicle that is stopped with warning devices indicating an emergency (such as flares). 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 Oregon, always check the local traffic laws.
