A DUI conviction for a commercial driver can mean financial ruin, and the BAC applicable to commercial drivers is exceedingly low – .004 %. This means that commercial drivers can be convicted of a DUI with half the level of impairment. This is not an accident and is very purposeful in the law. While cars are dangerous implements if driven recklessly or dangerously, semi-trucks and full size big rigs carry dangers exponentially greater to public safety when operated by impaired drivers. If you are a commercial driver cited with DUI, you need an attorney, every case, no matter how low you may believe your BAC to have been. Simply put, the consequences of conviction are simply too great for you to roll the proverbial dice, lifelong Las Vegas resident or not, this is a gamble not worth making.
