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 Texas handbook says a solid yellow line on your side of the road marks a no-passing zone. It also says broken or dashed lines permit you to pass or change lanes when it is safe, and that you should not cross a solid yellow line. So the line on your side is telling you passing is not allowed there; it is not a signal to slow down or to pass cautiously.
Why the other answers are wrong
- A. Slow down. — Slowing down is not what the handbook says this line marks; a solid yellow line on your side marks a no-passing zone.
- B. Pass with caution. — Passing is permitted with broken or dashed lines when safe, but a solid yellow line on your side marks a no-passing zone.
- D. Keep right on hills. — The passages do not give this line a hills-specific “keep right” meaning; they tie a solid yellow line on your side to no passing.
Remember it
If the yellow line beside you is solid, treat it as a no-passing sign.
