You may pass a vehicle when:
A single broken line indicates that drivers may cross from either lane to change lanes. Dashed yellow lines alongside solid yellow lines indicate that passing is permitted from the lane next to the broken line, but not from the lane next to the solid line. Only change lanes when it is safe to do so.
