b. Except when overtaking and passing on the right is permitted, the driver of a vehicle being overtaken shall give way to the right in favor of the overtaking vehicle with or without audible signal and shall not increase the speed of his or her vehicle until completely passed by the overtaking vehicle.

2. No vehicle shall be driven to the left side of the center of the roadway in overtaking and passing another vehicle proceeding in the same direction unless such left side is clearly visible and is free of oncoming traffic for a sufficient distance ahead to permit such overtaking and passing to be completely made without interfering with the safe operation of any vehicle approaching from the opposite direction or any vehicle overtaken.

The Oklahoma department of highways as regards state and federal highways, and the city council as regards all other streets and highways, are authorized to determine those portions of a street or highway where overtaking and passing or driving to the left of the roadway would be especially hazardous, and shall, by appropriate signs or markings on the roadway, have the beginning and end of such zones indicated. When such signs or markings are in place and clearly visible to an ordinarily observant person, every driver of a vehicle shall obey the directions thereof.
2. Where signs or markings are in place to define a no passing zone as set forth in subsection D1 of this section, no driver shall at any time drive to the left side of the roadway within such no passing zone or on the left side of any pavement striping designed to mark such no passing zone throughout its length.
