The alcohol concentration limit in Montana is .08, with the number
referring to grams of alcohol per 100 milliliters of blood or grams of
alcohol per 210 liters of breath. For drivers under the age of 21 it is .02. It
is also illegal to operate of commercial vehicle by person with alcohol
concentration of 0.04 or more. Drivers in Montana are considered to
have given consent to blood or breath tests to determine the presence of
alcohol or drugs. An arrested person may refuse to submit to such a
test, but Montana law then allows a peace officer to seize the driver's
license. The license may then be suspended or revoked and the length
of the suspension depends on whether it is a first refusal or second or
subsequent refusal.
