A solid yellow pavement marking indicates you cannot cross or pass.

Answer: C — You cannot cross or pass

Solid yellow centerlines tell you not to pass. They’re put in places where incoming traffic or limited visibility makes passing dangerous, so you’re expected to stay in your lane and not cross the line to overtake. The phrase you’re learning here is that crossing or passing when you see this marking is not allowed. You would only pass when the line becomes dashed on your side or if you’re turning left in a safe, appropriate way at a intersection or into a driveway, but not to pass another vehicle.
