Double solid yellow lines painted down the middle of the road mean:
- Railroad crossing ahead.
- Pedestrian crossing ahead.
- Passing is not permitted from either direction. ✓
- Passing is permitted from either direction.
Answer: C. Passing is not permitted from either direction.
Double solid yellow lines mean passing is not permitted from either direction.
Why this is the answer
The handbook says yellow lines divide traffic moving in opposite directions, and it describes double solid lines as a marking you cannot pass or change lanes across. It also says you may not go over those lines except to turn left into or out of a highway, such as a driveway, or to make a U-turn. Because the restriction applies to the line itself, it holds for traffic on both sides, so neither direction may pass. The manual points to Chapter 6 for the detailed passing rules.
Why the other answers are wrong
- A. Railroad crossing ahead. — Double solid yellow lines are pavement markings that separate opposite-direction traffic, not a sign or marking that warns of a railroad crossing ahead.
- B. Pedestrian crossing ahead. — Pedestrian crossings are shown with crosswalk lines painted across the road, not by double solid yellow center lines.
- D. Passing is permitted from either direction. — Double solid lines are not like a broken line; the manual says you cannot pass or change lanes across them.
Remember it
Yellow tells you opposing traffic is on the other side; when both lines are solid, treat the pair as off-limits for passing.
