Two solid yellow lines on the pavement mean:
- Passing is allowed for drivers from both directions.
- Passing is not allowed. ✓
- Passing is allowed if you are at the top a hill.
- Passing is allowed during daylight only.
Answer: B. Passing is not allowed.
Two solid yellow lines mean passing is not allowed.
Why this is the answer
The Texas handbook says a solid yellow line on your side of the road marks a no-passing zone. Broken or dashed lines are the ones that permit passing or lane changes when it is safe. If both sides have solid yellow lines, neither direction has the dashed permission, so passing is not allowed. Another passage also warns not to cross yellow lines where limited sight distance makes passing hazardous.
Why the other answers are wrong
- A. Passing is allowed for drivers from both directions. — Passing in both directions would require permission to cross, but a solid yellow line on your side marks a no-passing zone.
- C. Passing is allowed if you are at the top a hill. — Being at the top of a hill does not create a passing exception; the handbook says limited sight distance makes passing hazardous and yellow lines mean do not cross.
- D. Passing is allowed during daylight only. — The handbook does not make solid yellow lines a daylight-only rule; a solid yellow line on your side marks a no-passing zone.
Remember it
Treat a solid yellow line on your side like a wall: do not cross it to pass.
