Which statement about yellow lines is NOT true?

• A. They indicate traffic going in your direction (such as one-way streets)
• B. They indicate traffic going in the opposite direction
• C. They indicate the edge of the roadway
• D. They indicate a no-passing zone

Answer: (B)

Yellow lines mark the center of the road and separate opposing traffic. They show passing rules: a dashed line on your side means you may pass if safe; a solid line on your side means you must not pass. They also help you stay in your lane on two-way streets. The edge of the roadway is indicated by white lines, not yellow, so describing yellow lines as marking the road’s edge isn’t accurate. Also, one-way streets aren’t determined by yellow centerlines alone—other signs or markings indicate direction.
