What does a solid white line on the road mean?

• A. Change lanes with caution
• B. Do not change lanes
• C. Passing is allowed
• D. Traffic is moving in opposite directions

Answer: (B)

A solid white line on the road serves as a guideline indicating that changing lanes is not permitted. This type of line is commonly found on roads with multiple lanes and helps to maintain the organization and flow of traffic. The presence of a solid white line signifies that drivers should stay in their current lane and only change lanes if necessary and when it can be done safely. It provides clear guidance aimed at enhancing safety by preventing lane changes that could result in collisions or other dangerous situations. In contrast, a dashed white line would indicate that lane changes are allowed, whereas solid yellow lines would denote no passing in the opposite direction, highlighting how different line types communicate distinct rules and regulations on the road.
