Who is prohibited from driving in exclusive lanes for buses?

The correct answer indicates that all other vehicles are prohibited from driving in exclusive lanes designated for buses. These exclusive lanes are specifically designed to provide priority for buses, enhancing their operational efficiency and ensuring that public transportation can meet schedule demands without being delayed by other traffic.

When these lanes are reserved for bus use, it maximizes the capacity and reliability of bus services, allowing for smoother traffic flow and improved public transit accessibility. The prohibition of all other vehicles in these lanes is crucial because the presence of non-bus vehicles could lead to congestion and delays, ultimately undermining the purpose of having exclusive lanes for buses.

In contrast, the other options suggest limitations on which types of vehicles are restricted, but they do not fully capture the comprehensive nature of the prohibition that ensures that only buses can operate in these lanes. This understanding is essential for maintaining an efficient roadway system, particularly in busy urban areas where public transportation plays a vital role in reducing traffic congestion.
