Under current law, a person may not operate a motor vehicle, an all-terrain
vehicle (ATV), a snowmobile, or a motorboat if he or she: 1) has an alcohol
concentration of 0.1 or more in his or her blood, breath, or urine; or 2) is under the
influence of an intoxicant (alcohol, drugs, or a combination of alcohol and drugs) that
impairs his or her ability to operate the motor vehicle, ATV, snowmobile, or
motorboat safely. Penalties for a person who violates one of these prohibitions (which
include suspension of the person's driver's license) depend on the number of prior
offenses, whether the person injured or killed another as a result of operating the
motor vehicle, ATV, snowmobile, or motorboat, and, if another person was injured,
the extent of that person's injury. Current law, however, provides a person a defense
to prosecution for causing injury or death if the person can prove that the injury or
death would have occurred even if he or she had been exercising due care and did not
have a prohibited alcohol concentration or was not under the influence of an
intoxicant. Current law also prohibits a person from operating or going armed with
a firearm while under the influence of an intoxicant, with more severe penalties
applying if another person is killed as a result.
This bill prohibits a person from operating a motor vehicle, an ATV, a
snowmobile, or a motorboat or operating or going armed with a firearm if he or she
has a detectable amount of a restricted controlled substance in his or her blood,
regardless of whether the person's ability to operate the motor vehicle, ATV,
snowmobile, or motorboat safely has been impaired. The bill defines a restricted
controlled substance as: 1) delta-9-tetrahydrocannabinol (the primary active

ingredient in marijuana); 2) a controlled substance (other than marijuana) included
in Schedule I under the state's controlled substance law, which includes heroin, LSD,
PCP, and certain "club drugs"; 3) cocaine or any of its metabolites; and 4)
methamphetamine. Penalties for a person who violates one of these prohibitions are
the same as those that would apply if the person had a prohibited alcohol
concentration or had been under the influence of an intoxicant. The bill, however,
provides a person who has a detectable amount of a restricted controlled substance
in his or her blood a defense to causing death or injury if the person can prove that
the injury or death would have occurred even if he or she had been exercising due care
and did not have a detectable amount of a restricted controlled substance in his or
her blood. In addition, a person has a defense to prosecution for any offense created
under the bill that is based on the person having a detectable amount of
methamphetamine or delta-9-tetrahydrocannabinol in his or her blood if the person
can prove that he or she had a valid prescription for methamphetamine, a drug that
metabolizes into methamphetamine, or delta-9-tetrahydrocannabinol.
Because this bill creates a new crime or revises a penalty for an existing crime,
the Joint Review Committee on Criminal Penalties may be requested to prepare a
report concerning the proposed penalty and the costs or savings that are likely to
result if the bill is enacted.
Because this bill proposes to revoke a person's operating privilege upon
conviction for an offense, the Department of Transportation, as required by law, will
prepare a report to be printed as an appendix to this bill.
For further information see the state and local fiscal estimate, which will be
printed as an appendix to this bill.
