What is a primary purpose of transit lanes on some roadways?

Answer: B — Reserved for buses only

The primary purpose of transit lanes is to improve the efficiency and reliability of public transportation by reserving special lanes primarily for buses. These lanes help facilitate faster travel for transit vehicles, ensuring they are less impacted by general traffic congestion. By giving priority to buses, transit lanes contribute to increased ridership and can encourage more people to use public transit options. When buses can operate more smoothly and quickly, it enhances the overall effectiveness of the public transportation system. This not only benefits bus passengers but also helps reduce congestion on the roadways, as fewer personal vehicles are needed for transport. The idea is to create a dedicated space where buses can function without interference from other types of vehicles, thereby promoting public transportation as a viable and efficient option.
