What does a dashed white line on the road indicate?

Answer: C — Lane changes are permitted

A dashed white line on the road indicates that lane changes are permitted. This visual cue allows drivers to know that they can safely move from one lane to another, provided they check for any oncoming traffic and ensure that it is safe to make the maneuver. In areas where there are dashed lines, it is common to expect changing traffic patterns, such as merging lanes, and it is the driver's responsibility to execute the lane change cautiously. The other options describe scenarios that are not applicable to dashed white lines. For example, a solid line would indicate that lane changes are prohibited, while other specific markings serve different purposes, such as regulating left turns or signaling when to yield or slow down. Understanding these markings helps enhance road safety by promoting appropriate driver behaviors.
