Final answer:
Broken yellow lines indicate passing is allowed in one direction, while broken white lines indicate passing is allowed in both directions.
Step-by-step explanation:
Broken yellow lines and broken white lines are used to indicate different rules and restrictions for passing on highways and roads.
Broken yellow lines indicate that passing is allowed in one direction and not allowed in the other. For example, if you see broken yellow lines on your side of the road, it means you are allowed to pass vehicles traveling in the same direction as you, but not those going in the opposite direction.
On the other hand, broken white lines indicate that passing is allowed in both directions. Vehicles on either side of the road are allowed to pass as long as it is done safely and legally.
