Double solid yellow line markings down the center of a road indicate that passing is:
- Allowed from both directions.
- Allowed only from your direction of travel.
- Not allowed from either direction. ✓
Answer: C. Not allowed from either direction.
A double solid yellow line down the center means passing is not allowed from either direction.
Why this is the answer
The manual explains that yellow lines separate traffic moving in opposite directions, and that a solid line on your side means you cannot pass or cross it. With two solid yellow lines, each direction of travel faces a solid line, so neither side may cross to pass. The manual's breakdown of double solid lines is cut off in the excerpt, but the rule it gives for a solid line on your side covers both directions here. Cross only where a left turn into a driveway is permitted, as the manual allows for a solid line.
Why the other answers are wrong
- A. Allowed from both directions. — Passing from both directions would mean crossing solid yellow lines on both sides, which the manual does not allow.
- B. Allowed only from your direction of travel. — Passing from just one direction ignores that the solid line applies to drivers on each side of the two lines, not only one.
Remember it
Think of it as a wall of yellow paint: a solid line on your side tells you to stay in your lane, and two solid lines mean both sides stay put.
