California permit test: lane markings and lane types

Paint tells you which way traffic moves and what you may do in each lane. Yellow divides directions, white divides lanes going the same way.

Key rules

• Yellow lines separate opposite directions. White lines separate lanes going the same way. Broken lines may be crossed when safe; solid lines discourage or prohibit crossing. (CVC §21460; DMV handbook)
• Two double-yellow sets 2 feet or more apart are a barrier: do not drive over, turn left or U-turn across them except at openings. (CVC §21651)
• Limit line: wide white line where you stop. Yield line: row of white triangles pointing at you. School crosswalks may be yellow. (DMV handbook, Lane Markings)
