People who drive for a living, such as truckers, postal workers, delivery drivers and more, face tighter restrictions on drinking and driving. If your job depends on your commercial driver's license (CDL), it may be especially critical to hire a DUI attorney to help you deal with criminal charges. Each state has different regulations, so if you are a commercial driver it's important to know legal limits. For example, in California, the legal limit for a commercial driver who is operating a commercial vehicle is a BAC of .04%. If arrested, commercial drivers may lose their ability to drive commercially for varying lengths of time. In some states, such as California, you are guaranteed to lose your CDL for at least one year for DUI, regardless of whether this was your first DUI offense or you were driving in a noncommercial vehicle. Unlike standard driver's licenses, in California, restricted CDLs are not available to allow driving for work, so you will be unable to drive commercially for a year. A DUI when you have a CDL can also make it difficult to get future work. If you rely on driving commercially for a living, having knowledgeable legal counsel can potentially save your livelihood.
