Which sign orientation indicates the middle lanes usually offer the smoothest flow of traffic on three-lane roads?

• A. Stripes point downward toward the safe side of the roadway.
• B. Stripes point upward.
• C. Stripes point to the left.
• D. Stripes indicate the distance to the object.

Answer: (A)

On three-lane roads, signs use stripe directions to guide you toward the lanes that typically carry through traffic most smoothly. When the stripes point downward toward the safe side of the roadway, that signals the center lanes usually offer the best, steady flow for through traffic. So this orientation tells you to favor the middle lanes for smoother travel. The other stripe directions don’t convey this lane-flow guidance—upward stripes don’t indicate the best lanes, stripes pointing left suggest a direction rather than lane quality, and stripes that indicate distance to an object aren’t about which lanes flow best.
