No court shall suspend the imposition of sentence as to such person nor sentence such person to a fine in lieu of a term of imprisonment, nor shall such person be eligible for parole or probation until he has served a minimum of forty-eight consecutive hours of imprisonment, unless as a condition of such parole or probation, such person performs at least ten days involving at least forty hours of community service under the supervision of the court in those jurisdictions which have a recognized program for community service. Upon receipt of such conviction the director shall disqualify such person's privilege to drive a commercial motor vehicle pursuant to section 302.755.
