A solid yellow line on your side of the centerline means:
- Slow down.
- Pass with caution.
- Do not pass. ✓
- Keep right on hills.
Answer: C. Do not pass.
A solid yellow line on your side of the centerline means do not pass.
Why this is the answer
The manual ties yellow lines to traffic moving in opposite directions. It says a driver on the solid-line side cannot pass or cross the line, except for a left turn into a driveway. Chapter 6 repeats the passing rule: you cannot pass a vehicle on the left when your lane has a solid yellow center line. That is why the correct choice is the one saying you must not pass. The rule does not tell you to slow down or to pass carefully.
Why the other answers are wrong
- A. Slow down. — Slowing down is not what the line means; the manual uses it to control passing and crossing, not to set a slower speed.
- B. Pass with caution. — Passing with caution is allowed from the broken-line side, not when the solid line is on your side.
- D. Keep right on hills. — Keeping right on hills is not given as the meaning of a solid yellow line in the passages; the line is about not passing when it is on your side.
Remember it
Think of a solid yellow line on your side as a wall for passing.
