You are driving in the far right lane of a four-lane freeway and notice thick broken white lines on the left side of your lane. You are driving in:
- The carpool lane and must merge into the next lane.
- A special lane for slow-moving vehicles.
- An exit lane. ✓
Answer: C. An exit lane.
You are driving in an exit lane.
Why this is the answer
The handbook says freeway lanes that are ending are typically marked with big broken lines. Those markings warn you to prepare for an exit or for the lane to finish. Thick broken white lines on the left side of the far right lane fit that warning, so the lane is an exit lane rather than a regular through lane.
Why the other answers are wrong
- A. The carpool lane and must merge into the next lane. — A carpool lane uses a diamond symbol and the label Carpool Lane, and double solid white lines separate it; it is not shown by the big broken lines that signal an ending lane.
- B. A special lane for slow-moving vehicles. — The handbook mentions turnout areas or lanes for slow vehicles on two-lane roads, not a freeway lane with thick broken white lines, so this is not a special slow-moving vehicle lane.
Remember it
Big broken lines mean the lane is ending; get ready to exit or merge.
