What type of traffic is allowed in 'Transit' lanes on some roadways?

Transit lanes are specifically designed to prioritize public transportation, such as buses, in order to promote a more efficient and reliable transit system. These lanes often allow buses to move more freely through traffic, thereby reducing travel times and encouraging the use of public transit. In many cases, these lanes may also be used for carpools or vanpools, but the primary focus is on buses, making them the main type of vehicle permitted in these designated lanes.

While bicycles and other vehicle types may be allowed in other lanes, transit lanes specifically cater to larger forms of public transport to maximize their efficiency. Consequently, while cars and bikes may have their own designated lanes on certain roads, they are not permitted in transit lanes. Thus, buses are the definitive answer when it comes to traffic allowed in these specific lanes.
