acts alleged to have been committed in violation of 23-2-523(2).
(2) Evidence of any measured amount or detected presence of alcohol or drugs in a person at the
time of the act alleged, as shown by analysis of the person's blood, breath, oral fluid, or urine, and any other
competent evidence bearing on the question of whether the person was under the influence of alcohol, drugs,
or a combination of the two at the time of the act alleged is admissible in any criminal action or proceeding
arising out of acts alleged to have been committed in violation of 23-2-523(2).
(3) If a person charged with violation of 23-2-523(2) refuses to submit to a test of the person's
blood, breath, or urine for the purpose of determining any measured amount or detected presence of alcohol, or
drugs, none will be given, but proof of refusal is admissible in any criminal action or proceeding arising out of
acts alleged to have been committed in violation of 23-2-523(2).
(4) The provisions relating to administration of tests provided in 61-8-1019 and the definition of
alcohol concentration provided in 61-8-1001 apply to any testing done to a person charged with violation of 23-

ENROLLED BILL
(5) As used in 23-2-523(2), the term "under the influence" has the meaning provided in 61-8-
1001."
Section 2. Section 61-2-302, MCA, is amended to read:
"61-2-302. Establishment of driver rehabilitation and improvement program -- participation by
offending drivers. (1) The department may establish by administrative rule a driver rehabilitation and
improvement program or programs. The programs may consist of electronic or classroom instruction in rules of
the road, driving techniques, defensive driving, driver attitudes and habits, actual on-the-road driver's training,
and other subjects or tasks designed to contribute to proper driving attitudes, habits, and techniques and must
include the requirements for obtaining a restricted probationary driver's license.
(2) Except when otherwise provided or restricted by statute, a person whose driver's license is
suspended or revoked by the department, unless the suspension or revocation was for an offense under 61-8-
1002(1)(a), (1)(b), (1)(c), (1)(d), or (1)(e), or (1)(f), may participate in any driver rehabilitation and improvement
program established under this section if the person's license is:
(a) suspended as a result of a violation of the traffic laws of this state, unless the suspension was
imposed under the authority provided in Title 61, chapter 8, part 8; or
(b) revoked and the person has:
(i) completed at least 3 months of a 1-year revocation; or
(ii) completed 1 year of a 3-year revocation; and
(iii) met the requirements for reobtaining a Montana driver's license.
(3) Notwithstanding any provision of this part inconsistent with any other law of the state of
Montana, the enforcement of any suspension or revocation order that constitutes the basis for any person's
participation in the driver rehabilitation and improvement program provided for in this section may be stayed if
that person complies with the requirements established for the driver rehabilitation and improvement program
and meets the eligibility requirements of subsection (2).
(4) If a person's driver's license has been surrendered before the person's selection for
participation in the driver rehabilitation and improvement program, the license may be returned upon receipt of
the person's agreement to participate in the program.

ENROLLED BILL
(5) The stay of enforcement of any suspension or revocation action must be terminated and the
suspension or revocation action must be reinstated if a person declines to participate in the driver rehabilitation
and improvement program or fails to meet the attendance or other requirements established for participation in
the program.
(6) This part does not create a right to be included in any program established under this part.
(7) The department may establish a schedule of fees that may be charged to those persons
participating in the driver improvement and rehabilitation program. The fees must be used to help defray costs
of maintaining the program.
(8) A person may be referred to this program by a driver improvement analyst, city judge, justice of
the peace, youth court judge, or judge of a district court of the state.
(9) (a) Except as provided in subsection (9)(b), the department may issue a restricted probationary
license to any person who enrolls and participates in the driver rehabilitation and improvement program. Upon
issuance of a probationary license under this section, the licensee is subject to the restrictions set forth on the
license.
(b) The department may not issue a restricted probationary license that would permit an individual
to drive a commercial motor vehicle during a period in which:
(i) the individual is disqualified from operating a commercial motor vehicle under state or federal
law; or
(ii) the individual's driver's license or driving privilege is revoked, suspended, or cancelled.
(10) It is a misdemeanor for a person to operate a motor vehicle in any manner in violation of the
restrictions imposed on a restricted license issued to the person under this section."
Section 3. Section 61-5-212, MCA, is amended to read:
"61-5-212. Driving while license suspended or revoked -- penalty -- second offense of driving
without licensing exemption. (1) (a) A person commits the offense of driving a motor vehicle without statutory
exemption or during a suspension or revocation period if the person drives:
(i) a motor vehicle on any public highway of this state at a time when the person's privilege to
drive or apply for and be issued a driver's license is suspended or revoked in this state or any other state unless

- 4 - Authorized Print Version – HB 344
ENROLLED BILL

suspended, or cancelled in this state or any other state or the person is disqualified from operating a
commercial motor vehicle or from obtaining a commercial driver's license; or
(iii) a motor vehicle on any public highway of this state without proof of a statutory exemption, as
provided in 61-5-104.

exemption for the second time shall be punished by imprisonment for not less than 2 days or more than 6
months and may be fined not more than $500.
(ii) Except as provided in subsection (1)(b)(iii), a person convicted of the offense of driving during a
suspension or revocation period shall be fined an amount not to exceed $500 or be imprisoned for a term of not
more than 6 months, or both.
(iii) If the reason for the suspension or revocation was that the person was convicted of a violation
of 61-8-1002(1)(a), (1)(b), (1)(c), (1)(d), or (1)(e), or (1)(f) or a similar offense under the laws of any other state
or the suspension was under 61-8-1016 or a similar law of any other state for refusal to take a test for alcohol or
drugs requested by a peace officer who believed that the person might be driving under the influence, the
person shall be imprisoned for a term of not less than 2 days or more than 6 months or be fined an amount not
to exceed $2,000, or both, and in addition, the court may order the person to perform up to 40 hours of
community service.
(2) (a) Upon receiving a record of the conviction of any person under this section upon a charge of
driving a noncommercial vehicle while the person's driver's license, privilege to drive, or privilege to apply for
and be issued a driver's license was suspended or revoked, the department shall extend the period of
suspension or revocation for an additional 1-year period.
(b) Upon receiving a record of the conviction of any person under this section upon a charge of
driving a commercial motor vehicle while the person's commercial driver's license was revoked, suspended, or
cancelled or the person was disqualified from operating a commercial motor vehicle under federal regulations,
the department shall suspend the person's commercial driver's license in accordance with 61-8-802."

second or subsequent misdemeanor offense of driving under the influence of alcohol or drugs under 61-8-
1002(1)(a), (1)(b), (1)(c), (1)(d), or (1)(e), or (1)(f), driving with excessive alcohol concentration under 61-8-
1002, or aggravated driving under the influence as defined in 61-8-1001 is participating in a DUI court as
defined in 61-8-1001, the court may, in the court's discretion, authorize a probationary driver's license for the
participant subject to 61-8-1010 and any other conditions imposed within the scope of the court's authority.
(2) If the participant fails to comply with the court's conditions, the court may revoke the
probationary driver's license and impose a driver's license suspension for the time period established pursuant
to 61-5-208 commencing from the date of the court's revocation of the probationary license."
Section 5. Section 61-8-805, MCA, is amended to read:
"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.

ENROLLED BILL
(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 the purposes of this section, a conviction for violation of 61-8-1002(1)(a), (1)(b), (1)(c),
(1)(d), or (1)(e), or (1)(f) 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)."

ENROLLED BILL
"61-8-1002. Driving under influence. (1) A person commits the offense of driving under the influence

(2) Upon the trial of any civil or criminal action or proceeding arising out of acts alleged to have
been committed by any person driving or in actual physical control of a vehicle while under the influence of
alcohol, the concentration of alcohol in the person at the time of a test, as shown by analysis of a sample of the
person's blood, breath, or other bodily substance drawn or taken within a reasonable time after the alleged act,
gives rise to the following inferences:
(a) if there was at that time an alcohol concentration of 0.04 or less, it may be inferred that the
person was not under the influence of alcohol;
(b) if there was at that time an alcohol concentration in excess of 0.04 but less than 0.08, that fact
may not give rise to any inference that the person was or was not under the influence of alcohol, but the fact
may be considered with other competent evidence in determining the guilt or innocence of the person; and
(c) if there was at that time an alcohol concentration of 0.08 or more, it may be inferred that the
person was under the influence of alcohol. The inference is rebuttable.
(3) The provisions of subsection (2) do not limit the introduction of any other competent evidence
bearing on the issue of whether the person was under the influence of alcohol, drugs, or a combination of
alcohol and drugs.
(4) Each municipality in this state is given authority to enact this section, with the word "state"
changed to read "municipality", as an ordinance and is given jurisdiction of the enforcement of the ordinance
and the imposition of the fines and penalties provided in the ordinance.
(5) Absolute liability, as provided in 45-2-104, is imposed for a violation of this section.
(6) When the same acts may establish the commission of an offense under subsection (1), a
person charged with the conduct may be prosecuted for a violation of another relevant subsection under
subsection (1). However, the person may be convicted of only one offense under this section or of a similar
offense under previous laws of this state."

(4) The assessment must describe the defendant's level of addiction, if any, and contain a
