61-8-805. Suspension for operating commercial vehicle with alcohol concentration of 0.04 or more -- hearing. (1) A person whose alcohol concentration is 0.04 or more while the person drives or is in actual physical control of a commercial motor vehicle is subject to the suspension of the person's commercial driver's license. The peace officer who determines that the person is operating a commercial motor vehicle with an alcohol concentration of 0.04 or more shall immediately seize the person's commercial driver's license and, on behalf of the department, give the person written notice of the license suspension and the right to a hearing under 61-8-808. Upon receipt of a report certified under penalty of law from the peace officer that the person was operating a commercial motor vehicle with an alcohol concentration of 0.04 or more, the department shall suspend the license, with no provision for a restricted probationary commercial license, for:

(a) 1 year, upon receipt of the first report of a 0.04 or more alcohol concentration violation, except that if the violation occurred in a commercial motor vehicle transporting placardable hazardous materials, the suspension must be for 3 years; and

(b) life, upon receipt of a second or subsequent 0.04 or more alcohol concentration violation report at any time as determined from the records of the department, subject to federal rules allowing for driver rehabilitation and license reinstatement, if otherwise eligible, upon service of a minimum period of 10 years' suspension.

(2) A peace officer who determines that a commercial motor vehicle operator has a measured amount or detected presence of alcohol in the operator's body while operating a commercial motor vehicle shall place the commercial motor vehicle operator out of service as mandated by federal regulations for 24 hours.

(3) The fact that a person charged with a violation of the provisions of subsection (1) is entitled to use alcohol under the laws of Montana is not a defense against a charge of violating the provisions of subsection (1).

(4) For purposes of this section, a conviction for violation of 61-8-1002(1)(a), (1)(b), (1)(c), (1)(d), or (1)(e) while operating a commercial motor vehicle or a prior refusal to be tested under an implied consent law must be treated as a prior report of a 0.04 or more alcohol concentration violation and must be used in determining the length of the license suspension under subsection (1).
