What does the California vehicle code state about driving in bus-only lanes?

Answer: C — You can use these lanes unless making a turn

The correct answer emphasizes the conditions under which a driver may use bus-only lanes. According to the California vehicle code, drivers are allowed to enter bus-only lanes under specific circumstances, such as when preparing to make a turn. This means that while these lanes are primarily designated for buses to ensure efficient public transportation, they can be legally accessed by other vehicles if they are turning at an intersection or driveway, thus ensuring that the lanes are not misused but still allow for some flexibility in their use. In this context, driving in bus-only lanes is not outright prohibited, as long as it aligns with the stipulations regarding turning. This is important for maintaining traffic flow and ensuring that buses can operate efficiently while still accommodating drivers' needs when necessary. Just driving in bus-only lanes without these conditions applicable would be considered a violation, as these lanes are primarily reserved for buses to enhance public transportation and reduce congestion.
