Final answer:
Passing on both sides of the dividing lines on a highway is only allowed in certain situations depending on traffic laws.
Step-by-step explanation:
Passing on both sides of the dividing lines on a highway is only allowed when certain conditions are met. These conditions can vary depending on the specific traffic laws of the country or state. In general, passing on both sides may be allowed when there is a broken dividing line and it is safe to do so. However, passing on both sides is usually not allowed when there is a solid dividing line, indicating that passing is prohibited. It is important for drivers to familiarize themselves with the specific traffic laws in their area to know when passing is permitted.
