Double Solid White Lines indicate what?

Double Solid White Lines indicate what?

• A. A barrier between traffic moving in the same direction.
• B. A barrier between a regular-use lane and a carpool or other preferential-use lane.
• C. A barrier at the edge of the road.
• D. A warning of a sharp curve.

Answer: (B)

Double solid white lines show a boundary you should not cross. They act as a barrier between lanes that run in the same direction, and crossing them is not allowed. In California, you’ll often see this barrier separating a regular-use driving lane from a carpool or other preferential-use lane, which is why the emphasis here is on the separation between a standard lane and a carpool lane. Stay in your lane and don’t cross these lines unless you’re at a designated point where crossing is permitted for entering or exiting, or turning as allowed by signs. The other ideas don’t fit because these markings aren’t about the edge of the road, a curve warning, or a barrier between opposite-direction traffic.
