Missouri's Move Over Law

  • Missouri's "Move Over" Law, RSMo 304.022, states:
    • ” 2.  Upon approaching a stationary vehicle displaying lighted red or red and blue lights, or a stationary vehicle displaying lighted amber or amber and white lights, the driver of every motor vehicle shall:
      •  (1)  Proceed with caution and yield the right-of-way, if possible with due regard to safety and traffic conditions, by making a lane change into a lane not adjacent to that of the stationary vehicle, if on a roadway having at least four lanes with not less than two lanes proceeding in the same direction as the approaching vehicle; or
      •  (2)  Proceed with due caution and reduce the speed of the vehicle, maintaining a safe speed for road conditions, if changing lanes would be unsafe or impossible.”
  • Missouri’s Move Over law requires drivers to change lanes, if safe to do so, when approaching MoDOT vehicles, law enforcement vehicles, and any other emergency vehicle with lights flashing. If drivers can’t change lanes safely, they must slow down as they pass the emergency vehicles.
  • This Missouri law helps provide a safer area for law enforcement, emergency vehicles, and transpor­tation workers as they perform their official du­ties. Missouri’s Move Over law requires drivers to approach cautiously when an emergency ve­hicle displaying red or red and blue lights or a vehicle owned by the state highways and trans­portation commission displaying lighted amber or amber and white lights is stopped along the side of the road. Motorists must change lanes away from the emergency vehicle if they are on a multi-lane highway and can SAFELY do so. If drivers can’t change lanes safely, or they are on a two-lane highway, they must slow down while maintaining a safe speed so as not to impede other traffic. A violation can result in fines and/ or imprisonment.
