Delaware Defensive Driving Practice Test

A dashed white line in traffic markings indicates that the lanes of traffic are separate but that changing lanes is permitted. This type of marking allows drivers to switch lanes safely, indicating that there is enough space to do so and that it is legal to move between lanes. The presence of a dashed line suggests that while the lanes are distinct, they can be crossed, which aids in managing traffic flow and enabling vehicles to navigate through their environment more easily. The other choices point to different situations: a no parking zone is typically marked by solid lines or signage, a speed limit change would be indicated by posted signs rather than a line, and pedestrian areas are generally marked with specific symbols or solid lines, not dashed. Understanding the meaning of dashed white lines is crucial for safe driving practices, as it helps drivers make informed decisions when changing lanes.
