What should be done when encountering zipper markings while driving?

Answer: C — Do not cross or go beyond them

When you encounter zipper markings while driving, it signifies an important road condition that requires compliance with specific traffic regulations. Zipper markings are typically used to delineate lanes, particularly in situations where lanes are merging or changing. They indicate that drivers should not cross these markings, as doing so can lead to confusion, accidents, or unsafe merging situations. By choosing to not cross or go beyond these markings, drivers are adhering to the traffic guidelines designed to maintain safe driving practices. This action helps ensure that traffic flows smoothly and reduces the risk of collisions. It is essential to respect these markings as they serve a critical role in lane management, especially in high-traffic areas or during construction seasons.
