The term School bus is used in the United States, but also in Canada, to name a specific type (actually 4 different subtypes) of buses used to transport students to school and from school to home, whose roots date back to the end of the 19th century. Depending on the individual states or even counties, these buses are leased, leased or are in the possession of appropriate authorities responsible for their operation. Most often it is a given educational institution, although there are exceptions to this rule. It is also worth adding that these school buses are designed and manufactured in the USA from scratch, as a kind of separate type of bus on the American market. Currently, the School bus is produced by such plants as, among others: Blue Bird Corporation, IC Bus, Micro Bird, Trans Tech and Lion Electric Company. It can be assumed that since 2000 there are four types of buses known as School bus in production. The first is Type A, which is able to carry from 16 to 36 passengers, and its weight does not exceed 10,000 kilograms. The second type is the Type B, which can carry from 30 to 36 passengers and its weight does not exceed 9,800 kilograms. It differs significantly from the Type A in terms of construction. The third type is called Type C, which can carry from 36 to 78 passengers, and its weight usually ranges from 10,400 to 13,400 kilograms. Finally, the largest type of school bus, the Type D, which can carry up to 90 passengers, and its weight usually ranges from 11,000 to 16,000 kilograms.
