What type of lines indicate different types of lanes in an interchange or an intersection?

Dotted white lines play an essential role in indicating different types of lanes at interchanges and intersections. These lines are used to mark lanes that allow for lane changes. For example, they might separate a regular traffic lane from a turn lane or highlight a lane that accommodates vehicles merging from a side road or exit ramp.

This distinction is important as it helps drivers understand where they can safely change lanes or navigate through complex traffic situations, especially in busy areas such as interchanges, where traffic flow can be more challenging. The presence of dotted white lines signals to the driver that changing lanes is permitted and safe to do so, thus enhancing overall safety and traffic efficiency.
