10/26/2017 – Beginning Wednesday, November 1, 2017 Oklahoma law enforcement can stop and ticket drivers who stay in the left lane unless they have a good 
reason to be there. The fine? $235.25 and court costs.
Oklahoma Legislature adopted the new law in May of this year, that prohibits being in the left-most lane of a roadway that has four or more lanes, such as a highway with two lanes of travel each, going in opposite directions. The message from the Department of Public Safety is that the left lane should be clear aside from some exceptions.
The new law states drivers can only be there if traffic conditions and traffic flow prevent you from merging right, if the road is configured in a way that keeps drivers in the left lane or if other vehicles will be merging onto the roadway. Police officials did state that drivers should still move over if they pass an emergency vehicle parked on the side of the road with its lights on.
The Oklahoma Department of Transportation has installed “slower traffic keep right” and “do not impede left lane” signs in 234 locations from state line to state line, except in the metro areas. OHP officials recognize that high-volume traffic in metropolitan areas such as Oklahoma City and Tulsa may require all lanes to be occupied at times.
Officials stated that drivers should not attempt to drive slowly in the left lane to prevent others from speeding. Drivers are still expected to obey speed limits and all other traffic laws as always.
