Which side of a highway is a school bus prohibited from stopping on?

A school bus is prohibited from stopping on the left-hand side of a highway because it poses significant safety risks. When a bus stops on the left side, it can create confusion for other drivers, as they may not expect a bus to stop there, especially if they are driving in the opposite direction. Buses are designed to primarily stop on the right side of the road to allow students to board and exit safely.

Stopping on the left-hand side would also put children at risk when crossing the street to access or leave the bus, as they would have to cross multiple lanes of traffic, which increases the potential for accidents. Hence, it is crucial for school buses to stop on the right side of the road where the driver and passengers can safely manage the boarding and disembarking process.

The prohibition on stopping in the middle lane also relates to safety, as it would not provide a safe zone for children. Stopping on any divided highway is similarly discouraged because divided highways typically have multiple lanes of traffic and medians, which complicates the process of crossing safely.
