Drivers may not pass from either side of a ____ centerline.
- Combination solid and broken yellow
- Single broken yellow
- Double solid yellow ✓
- Single broken white
Answer: C. Double solid yellow
Drivers may not pass from either side of a double solid yellow centerline.
Why this is the answer
The Texas handbook says not to cross the double yellow line to pass. It also explains that a solid yellow line on your side marks a no-passing zone, while broken or dashed lines permit passing or lane changes when safe. A double solid yellow centerline puts a solid yellow line on both sides, so the no-passing rule applies to traffic on either side.
Why the other answers are wrong
- A. Combination solid and broken yellow — A combination line includes a broken side that permits passing when safe, so it does not match a centerline where passing is barred from both sides.
- B. Single broken yellow — A single broken yellow line permits passing or changing lanes when safe, so it is not a line where passing is barred from either side.
- D. Single broken white — A single broken white line is not the double solid yellow centerline described for no passing, and broken lines permit lane changes when safe.
Remember it
Picture two solid yellow lines as a wall you do not cross to pass.
