  3. Article 12-B. Approval of Motor Vehicle Accident Prevention Courses

§ 399-f. Proof of effectiveness. Proof of effectiveness shall be

verifiable research documentation submitted by the applicant for

sponsorship showing evidence of effectiveness comparable to that of the

national safety council's defensive driving course as determined by the

commissioner in terms of reduced convictions or accidents or both. This

research documentation shall employ accepted research principles and

include treatment and non-treatment control groups comprised of samples

of the representative driver base. In order to establish verifiable

effectiveness, each sample group should be comprised of a minimum of

three thousand drivers selected randomly. The documentation shall

include conviction or accident data for each motorist for a period of at

least eighteen months prior to the course completion date and at least

eighteen months subsequent to such date, and equivalent time periods for

non-treatment control groups. The documentation shall also include a

description of the sampling and analytic procedures used, and the

motorist identification number and course completion date for all course

attendees. The applicant for sponsorship shall provide, at the request

of the commissioner and at the applicant's expense, all driving record

data and analysis used in the development of the submitted research

documentation. Submission of any fraudulent or intentionally misleading

data will disqualify that organization and all owners and principals

from participating or approval in the accident prevention course for a

period of ten years from submission date. The commissioner may, by

regulation, provide for a smaller sample group for specialized courses.
