Scope
1.1 This Standard specifies the chassis and body requirements and safety equipment requirements for school buses. Note: The main purpose of this Standard is to provide the safest possible vehicle for students using school buses. It needs to be stressed, however, that standards are not substitutes for thorough, ongoing, and comprehensive safety training of students and drivers.
1.2 This Standard applies to (a) Type A1, A2, B, C, and D school buses; and (b) Type A1, A2, B, C, and D accessible school buses.
1.3 This Standard does not cover after-market and retrofit installations. These installations are covered by provincial and territorial regulations. Note: It is the responsibility of the appropriate jurisdiction to inspect and approve these installations.
1.4 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
1.5 The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
