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 the left side is clearly visible and is free from oncoming traffic for a sufficient distance ahead to permit 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. In every event the overtaking vehicle must return to the right-hand side of the roadway before coming within one hundred feet (100') of any vehicle approaching from the opposite direction.
