Answer: B. Yellow line next to your side of the road is broken
You may cross the double yellow lines to pass when the broken yellow line is next to your side of the road.
Why this is the answer
The handbook says a broken yellow line means you may pass if that broken line is next to your driving lane, and only when it is safe. Double solid yellow lines generally may not be crossed to pass; the handbook lists limited exceptions such as HOV entrances, signs directing you around a closure, and left turns into driveways or U-turns. Because the permission depends on the line on your side being broken, the line on the other side does not create permission for you.
Why the other answers are wrong
- A. Yellow line next to the other side of the road is broken — A broken yellow line on the opposite side describes the other direction's passing area, not yours.
- C. Vehicle in front of you moves to the right to let you pass — A vehicle moving right to let you pass does not change the line marking rule; the handbook's turnout-lane guidance is separate from permission to cross double yellow lines.
Remember it
Your side is the side that counts: look for the broken line beside your lane, not beside oncoming traffic.
