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 handbook describes double solid yellow lines as the marking that vehicles moving in either direction must not pass or cross. It allows a limited exception for turning left or passing a bicyclist when safe, but the general no-passing rule applies both ways. That matches the statement about not passing from either side. By contrast, a single broken yellow line may be crossed to pass when safe, and a combination yellow line depends on whether your side is solid or broken.
Why the other answers are wrong
- A. Combination solid and broken yellow — A combination solid and broken yellow line does not ban passing from both sides; the handbook ties passing to which side is solid or broken.
- B. Single broken yellow — A single broken yellow line is one you may cross to pass when it is safe to do so.
- D. Single broken white — A single broken white line separates lanes going the same direction and may be crossed to change lanes when safe, so it is not a centerline passing ban.
Remember it
Think of two solid yellow lines as a wall: neither direction crosses it to pass.
