Missouri Revised Statutes Title XIX. Motor Vehicles, Watercraft and Aviation § 302.272. School bus endorsement, qualifications--grounds for refusal to issue or renew endorsement--rulemaking authority--reciprocity

1. No person shall operate any school bus owned by or under contract with a public school or the state board of education unless such driver has qualified for a school bus endorsement under this section and complied with the pertinent rules and regulations of the department of revenue and any final rule issued by the secretary of the United States Department of Transportation or has a valid school bus endorsement on a valid commercial driver's license issued by another state. A school bus endorsement shall be issued to any applicant who meets the following qualifications:

2. The director of revenue, to the best of the director's knowledge, shall not issue or renew a school bus endorsement to any applicant whose driving record shows that such applicant's privilege to operate a motor vehicle has been suspended, revoked or disqualified or whose driving record shows a history of moving vehicle violations.

3. The director may adopt any rules and regulations necessary to carry out the provisions of this section. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in this section shall become effective only if it complies with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028. This section and chapter 536 are nonseverable and if any of the powers vested with the general assembly pursuant to chapter 536 to review, to delay the effective date, or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2004, shall be invalid and void.

4. Notwithstanding the requirements of this section, an applicant who resides in another state and possesses a valid driver's license from his or her state of residence with a valid school bus endorsement for the type of vehicle being operated shall not be required to obtain a Missouri driver's license with a school bus endorsement.
