HB 1155 -- Emergency Vehicles Sponsor: Shields This bill requires that every driver approaching a stationary motor vehicle stopped on the shoulder of a four-lane roadway make a lane change into a lane not adjacent to that of the stationary vehicle, if possible. If a lane change is not safe or possible, a driver must proceed with caution and reduce speed, maintaining a safe speed for the road conditions. Tow trucks must be treated in the same manner as law enforcement vehicles, ambulances, or any other emergency vehicle. Any driver who violates this provision is guilty of an infraction.Copyright (c) Missouri House of Representatives
