What does a solid white line indicate?

• A. Lane changes are allowed
• B. Lane restrictions; do not change lanes
• C. Speed limit changes ahead
• D. Start of a construction zone

Answer: (B)

A solid white line indicates lane restrictions, signaling that drivers should not change lanes. This marking is typically used to separate lanes of traffic moving in the same direction. When a solid white line is present, it serves as a visual instruction for drivers to remain in their lane; lane changes across this line are discouraged as doing so can lead to unsafe driving situations. Thus, recognizing and obeying this indicator is essential for maintaining safe driving practices and ensuring orderly vehicle movement. In contrast, a broken white line would allow lane changes, which is a distinction that drivers must be aware of when interpreting road markings. Understanding this aspect of road signage supports safe navigation and adherence to traffic regulations.
