Did you know you’re legally required to move into the next lane or slow down by 20 mph if an emergency vehicle (e.g. police car) is stopped on the side of the highway? If you didn’t know, that’s okay. Approximately 71 percent of Americans don’t know about this law either. You may also be shocked to discover that violating this "move over" law could cost you $2500. So the next time you’re on the road and see a police officer giving an unfortunate driver a ticket, remember to change lanes or slow down.
