A single broken yellow line down the center of a two-lane road indicates:
- Lanes are moving in opposite directions and drivers are not permitted to pass.
- Lanes are moving in opposite directions and drivers are permitted to pass when it is safe to do so. ✓
- Lanes are moving in the same direction and drivers are not permitted to pass.
- Lanes are moving in the same direction and drivers are permitted to pass when it is safe to do so.
Answer: B. Lanes are moving in opposite directions and drivers are permitted to pass when it is safe to do so.
A single broken yellow line means lanes are moving in opposite directions, and you may pass when it is safe to do so.
Why this is the answer
The handbook says yellow lane lines separate lanes moving in opposite directions. For a single broken yellow line, it tells you to stay to the right of the line and says you may cross it to pass a car ahead only when it is safe. That matches this answer: opposite-direction traffic, with passing allowed under safe conditions. The line does not by itself create a no-passing rule; the safety condition controls when you may cross.
Why the other answers are wrong
- A. Lanes are moving in opposite directions and drivers are not permitted to pass. — This says passing is never permitted, but the handbook allows you to cross a single broken yellow line to pass when it is safe.
- C. Lanes are moving in the same direction and drivers are not permitted to pass. — This says the lanes move in the same direction, but yellow lines separate lanes moving in opposite directions.
- D. Lanes are moving in the same direction and drivers are permitted to pass when it is safe to do so. — This says the lanes move in the same direction and passing is allowed, but yellow lines separate opposite-direction traffic, not same-direction lanes.
Remember it
Broken yellow: opposite traffic, but a safe gap lets you pass.
