What is the maximum speed limit when driving a school bus in a school zone?

The maximum speed limit when driving a school bus in a school zone is typically set at 20 mph unless otherwise posted. This speed limit is designed to ensure the safety of children who may be crossing the street or waiting at bus stops. Slower speeds allow for greater reaction time for drivers, enabling them to respond promptly to unexpected situations, such as children running into the road.

In many jurisdictions, including Oregon, this limit reflects a balance between traffic flow and the heightened risks associated with school zones. The law recognizes that school zones are areas with increased pedestrian traffic, especially during school start and dismissal times. It is essential for drivers, including those operating school buses, to adhere to this speed limit to help prevent accidents and ensure the safety of all students.

The specific designation of "unless otherwise posted" indicates that while this is the standard limit, there may be signage indicating a different speed limit in specific areas. Thus, it is crucial for drivers to be vigilant and observe posted speed limit signs to ensure compliance with local regulations.
