Why is 'Driving in marked lanes' essential for safety?

Driving in marked lanes is essential for safety because it helps prevent collisions. Marked lanes on roadways serve as clear guidelines for where vehicles should position themselves while traveling. By following these lane markings, drivers create a structured environment that reduces the likelihood of accidents. This organized system allows for predictable movement among vehicles, making it easier for drivers to judge distances and speeds of other vehicles. It ultimately enhances overall roadway safety by minimizing conflicts between vehicles that may occur if drivers were to drift outside their designated lanes.

While the other choices suggest some benefits of lane discipline or traffic regulation, they do not emphasize the direct connection between lane usage and safety as effectively as the prevention of collisions, which is the primary reason for maintaining lane discipline on the roads.
