School Bus

A school bus is a bus purpose-built or adapted to carry students to and from school and school-related activities, most closely associated in North America with a standardized yellow-painted design mandated by safety and visibility regulations adopted in the United States beginning in the 1930s. Built with reinforced body construction, high-backed seating, flashing warning lights and an extendable stop-sign arm intended to protect children boarding and exiting at the roadside, the type is one of the most tightly regulated classes of road vehicle in the countries that use it, reflecting the particular safety concerns of transporting large numbers of children. Outside North America, school transport is often provided by ordinary public buses or minibuses rather than a distinct dedicated vehicle type, making the standardized yellow school bus a design largely specific to the United States and Canada.
