On a freeway with 4 or more lanes in each direction, which lanes can a school bus legally occupy?

A school bus is required to prioritize safety and accessibility while transporting children. On a freeway with four or more lanes in each direction, the two lanes closer to the right edge are designated for slower-moving vehicles, which includes school buses. This regulation ensures that buses can operate safely without impeding faster traffic and allows for easier access to exit ramps or bus stops as needed.

Using the right lanes helps facilitate smoother traffic flow on the freeway while providing school buses with a suitable path for safe maneuvering. Other lanes, such as the left-most or middle lanes, are typically reserved for faster-moving traffic, which could pose a greater risk if a school bus were to occupy these lanes. Thus, the correct answer aligns with the established traffic rules intended to maintain safety for both school bus passengers and other road users.
