A two-way road has the single broken yellow center line shown. What does the marking permit?
Correct answer: Passing from either direction when the maneuver is otherwise safe and lawful.

You need to turn left into a driveway across solid yellow center lines, with no sign prohibiting the turn. What does Oklahoma's handbook say?
Correct answer: The lines do not prohibit this driveway turn, but you must wait until it is safe.
