Commercial drivers face harsher penalties for DUIs in Nevada than regular drivers. A commercial DUI is defined as having a BAC of 0.04% or higher while driving a commercial vehicle. Penalties for a first commercial DUI include 2-6 months in jail, fines of $400-$1,000, and community service. Subsequent DUIs result in heavier fines and jail time, with a third offense being a felony. Commercial drivers also face a mandatory 1 year suspension of their license for a first offense.
