California Car / Permit practice question · Signals & Pavement Markings
A broken white line between two lanes of traffic means:
Answer choices
- Traffic moves in opposite directions
- Lanes go the same way; you may change lanes when safe— Correct answer
- You may never cross the line
- The lane is reserved for buses
Why this is the answer
A broken white line separates lanes on roads with two or more lanes going the same direction. You may change lanes across it when it is safe, after signaling and checking your blind spots. Traffic in opposite directions is divided by yellow lines, so a white line never means oncoming traffic is in the next lane.
