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 are beside the broken yellow line, with a solid yellow line beyond it. How does the marking affect a proposed pass?

What do the two solid yellow center lines tell drivers who want to pass an ordinary car?
Correct answer: Passing across the lines is prohibited in both directions.

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.
The handbook prohibits passing across solid yellow center lines but permits crossing for a left turn. Check for other restrictions and wait for a safe gap; this exception is not permission to overtake a moving car.
