In addition to any penalty or condition imposed pursuant to the provisions of this subsection, the person shall be subject to an assessment of the person's degree of alcohol abuse, in the same manner as prescribed in subsection G of Section 11-902 of Title 47 of the Oklahoma Statutes, which may result in treatment as deemed appropriate by the court.
