Yellow lane markings separate

• A. Traffic traveling in opposite directions
• B. Traffic traveling in the same direction
• C. Pedestrian traffic only
• D. Bike lanes only

Answer: (A)

Yellow lane markings indicate the center of a two-way road and separate traffic moving in opposite directions. They guide you to stay on your side of the road. You cross them only when it’s safe and legal—for example, to pass when the line on your side is dashed, or to turn left where permitted. White lines, by contrast, separate lanes moving in the same direction, with dashed white lines allowing lane changes and solid white lines typically signaling you should stay in your lane. So the correct idea is that yellow markings separate opposing traffic.
