Final answer:
When two sets of solid double yellow lines are more than 2 feet apart on the road, it typically means that passing is allowed in one direction, with traffic traveling in the opposite direction being prohibited from crossing the yellow lines.
Step-by-step explanation:
When two sets of solid double yellow lines are more than 2 feet apart on the road, it typically means that there is a space for vehicles to legally pass between the lines. In most cases, passing is allowed only in one direction, with traffic traveling in the opposite direction being prohibited from crossing the yellow lines. This is commonly seen on two-lane roads where passing is permitted in certain sections, but caution should always be exercised when attempting to pass.
