The director, upon the receipt of that person's driver's license and a certified written report of the law enforcement officer in the form required by the director, forwarded by the officer within five days after issuing the temporary driver's permit, showing that the officer had reasonable grounds to believe the person had been driving or was in actual physical control of a commercial motor vehicle while in violation of section 39-06.2-10.1 or, had reason to believe that the person committed a moving traffic violation or was involved in a traffic accident as a driver, and in conjunction with the violation or accident the officer has, through the officer's observations, formulated an opinion that the person's body contains alcohol, that the person was lawfully detained, and that the person had refused to submit to the screening test under section 39-06.2-10.2, shall revoke that person's commercial driver's license or permit to drive and any nondomiciled commercial driver's privilege for the appropriate period under section 39-06.2-10, or if the person is a resident without a commercial driver's license or permit, the director shall deny to the person the issuance of a commercial driver's license or permit for the appropriate period under section 39-06.2-10 after the date of the alleged violation, subject to the opportunity for a prerevocation hearing and postrevocation review as provided in this chapter. In the revocation of the person's driver's license the director shall give credit for time in which the person was without a driver's license after the day of the person's refusal to submit to the test except that the director may not give credit for time in which the person retained driving privileges through a temporary driver's permit.
