How should motor vehicles act in advisory bicycle lanes?

• Drive slower than bicycles
• Use the lane when needed but yield to bicyclists
  Explanation:

  "Advisory bicycle lanes are becoming common on streets that are too narrow for a full bicycle lane but still have a lot of bicycle traffic. They are dashed on one or both sides to indicate that motor vehicles may use the lane space when necessary, but they must always yield to bicyclists first."
• Drive faster than bicycles
• Never enter the lane
