Can a driver cross a single broken white line on the highway?

A driver can indeed cross a single broken white line on the highway to change lanes. This line indicates that lane changes are permitted, provided that it is safe to do so. The broken white line serves as a guideline for drivers, signaling that they can move between lanes as necessary, for instance, to overtake another vehicle or to safely position themselves for an upcoming turn.

The rules governing lane changes imply that drivers must always check their mirrors and blind spots to ensure the maneuver is safe. Crossing a broken white line should be done with caution, ensuring that the road conditions and traffic allow for a safe transition. Understanding this rule is essential for safe driving practices on multi-lane roads.
