What does a broken white line between lanes of traffic signify?

Answer: C — You can change lanes with caution

A broken white line between lanes of traffic indicates that lane changes are permissible, provided the driver does so with caution. This marking allows vehicles to move between lanes safely, which is particularly useful for passing or navigating around slow-moving vehicles. Drivers should always signal their intentions and check their mirrors or blind spots to ensure the lane change can be completed safely. This line provides flexibility in traffic flow, contrasting with solid lines that would indicate restrictions on lane changes. Understanding this signaling is crucial for safe driving practices on the road.
