What does it indicate if you see a white dashed line between lanes?

The presence of a white dashed line between lanes signifies that changing lanes is permitted. This line allows drivers to move from one lane to another safely, assuming they have checked their mirrors and blind spots to ensure that it is clear to do so. The dashed line indicates that you are not in a restricted area, unlike solid lines which suggest that lane changes are discouraged or prohibited.

The correct interpretation of this traffic marking is essential for maintaining safe driving practices and ensuring smooth traffic flow. Therefore, when you see a white dashed line, it is a signal that you may proceed with changing lanes if conditions permit.
