What is the meaning of a dashed white line on the road?

A dashed white line on the road signifies that lane changes are allowed. This marking indicates that drivers may safely move from one lane to another, provided they observe the surrounding traffic conditions and signal their intentions appropriately. It is used to separate lanes of traffic moving in the same direction, providing flexibility for drivers to merge or change lanes as necessary.

In contrast, a solid white line would prohibit lane changes, as it indicates that the lane is intended to remain distinct from other lanes. Additionally, while a construction zone might have markers indicating its presence, dashed white lines are not specifically related to construction. Similarly, an ending lane would typically be marked with different indicators, such as a solid line or other cautionary symbols, to alert drivers of the upcoming change.
