What does a dashed white line signify?

A dashed white line on the roadway signifies that you may change lanes if it is safe to do so. This marking indicates that lane changes are permitted, allowing drivers to maneuver into other lanes when necessary. It is essential for drivers to ensure that the road is clear and it is safe before making such a maneuver.

In contrast, a solid white line indicates that lane changes are discouraged or not allowed, urging drivers to remain in their designated lanes. Other options, such as restrictions on turning or yielding to oncoming traffic, are not indicated by dashed white lines, further confirming that this type of line is about lane changing under safe conditions. Understanding these markings is crucial for safe driving and navigating roadways effectively.
