Commercial Drivers License and DUI in Wyoming

In Wyoming, bus drivers, truck drivers and other driving professionals are held to a higher standard than non-commercial drivers when it comes to driving under the influence as established by the Federal Motor Carrier Safety Administration (FMCSA). A BAC of 0.04% or more constitutes driving under the influence for an individual holding a commercial driver’s license. This is below the normal BAC of 0.08% for all other motorists. Further, failure to submit to a chemical test as required by the state’s laws regarding CDL’s also constitutes as grounds for a DUI arrest. If this is your first CDL DUI your license will be revoked for one year. A second CDL DUI offense will result in your CDL being revoked for life. Further, if you were carrying hazardous materials at the time of the DUI, your CDL will be revoked for three years. A second DUI offense while carrying hazardous materials will result in your license being revoked for life and you will never be able to operate a commercial vehicle again.

However, commercial drivers should not have any detectible amount of alcohol in their system and if you are pulled over with a BAC of less than 0.04%, you will be issued an “out-of-service” notice and will be unable to drive for the next twenty-four hours.
