At intersections, the bus-only lane may have what type of lines for vehicles other than buses?

In traffic regulations, specific lane markings indicate the rules for usage by different types of vehicles. In the case of a bus-only lane at intersections, the presence of broken or dashed lines signifies that while buses can use this lane freely, other vehicles may enter or cross it when necessary, such as to make turns or navigate around stopped buses. The dashed line indicates a permissive condition, allowing for limited and conditional use by vehicles other than buses, provided that it is safe to do so.

On the other hand, solid lines would indicate that vehicles should not enter that lane at any time, and double solid lines reinforce this restriction even more, prohibiting any crossing. The option stating "any type of lines" lacks the precision required, as it does not accurately reflect the specific regulatory framework governing bus lanes. In summary, the use of broken or dashed lines communicates a clear and functional guideline for the sharing of bus-only lanes alongside regular traffic, which is why it is the correct choice.
