What does a solid white line between lanes indicate?

• A. Lane changes are encouraged
• B. Lane changes are prohibited
• C. Lane changes are discouraged but not prohibited
• D. Lane changes are necessary

Answer: (C)

A solid white line between lanes indicates that lane changes are discouraged but not prohibited. This marking is commonly used on roadways to suggest that remaining in the same lane is safer, especially in areas where traffic patterns might change or where merging could create hazards. It serves as a visual cue for drivers to be cautious about changing lanes, emphasizing that while it is technically allowed, it is advisable to avoid doing so unless absolutely necessary—often due to safety concerns or the presence of other road users. This aligns with the goal of maintaining smooth traffic flow and reducing the likelihood of accidents. In contrast, options suggesting that lane changes are encouraged or necessary would misinterpret the intention of this marking, as the solid white line aims to promote safety rather than mandate action.
