Puerto Rico Learner's Permit Practice Test

A white dashed line on the road indicates that lane changing is permitted. This means that drivers can safely move from one lane to another as long as it is clear of obstacles and safe to do so. The presence of a dashed line allows for flexibility in lane usage, promoting smooth traffic flow and enabling drivers to navigate around slower vehicles or to prepare for turns when required.

In contrast, other markings, such as solid white lines, would indicate that lane changes should be avoided, thus emphasizing the importance of understanding road markings for safe driving practices.
