Using the right lane for driving on multi-lane roadways is primarily a matter of safety and efficiency in traffic flow. The correct answer emphasizes that the right lane should be used unless a driver is making a left turn or passing another vehicle.

This rule is based on the principle of keeping the left lanes available for faster traffic or those who are attempting to overtake slower-moving vehicles in the right lane. By maintaining this structure, roadways can facilitate smoother movement and reduce congestion. This practice also helps to ensure that the left lane serves its intended purpose for passing, while the right lane accommodates the majority of drivers who are not actively changing lanes or seeking to overtake.

In contrast, the other options do not accurately reflect the best practices for lane usage on multi-lane roads. For instance, the idea that one should only use the right lane when there is no traffic may compromise safety during busy periods. Similarly, limiting right lane usage to rush hour or specific weather conditions fails to recognize that the right lane should be the default lane for most driving scenarios, regardless of external factors.
