What does a solid yellow line on the driver's side of the centerline indicate?
- Crossing it for passing is dangerous and passing is not allowed
- Passing is encouraged whenever the opposing lane looks open
- The lane is reserved for vehicles making a U turn
- Only trucks may cross it to enter the shoulder
Answer: Crossing it for passing is dangerous and passing is not allowed. A solid yellow line in the driver’s lane marks a no passing condition. The manual explains that crossing it exposes the vehicle to approaching traffic or median obstacles, although a driver may cross the line to make a left turn. The open appearance of the opposing lane does not cancel the marking. A U turn or truck exception is not created by the line. The cue is simple: if the solid yellow is on your side, remain behind the slower vehicle unless a permitted left turn requires crossing.
