Yes. And the suspension times are harsh...
A first-time DUI by a commercial driver in Nevada carries a one-year-long suspension of his/her commercial driver's license (CDL). However, the suspension is increased to three years if he/she was transporting hazardous materials at the time.
Furthermore, any successive DUI by a commercial driver will cause his/her CDL to be suspended permanently. In other words, a second-time DUI can end someone's career as a commercial driver in Nevada.
Note that it does not matter whether the CDL-holder is driving a personal vehicle at the time of the DUI in Nevada. A commercial driver still stands to get his/her CDL suspended even if he/she drives drunk while off-duty and driving a non-commercial vehicle.
Also note that getting a DUI will also cause the driver's personal driver's license to be suspended as well:
- A first-time DUI carries a 90 day suspension.
- A second-time DUI carries a year-long suspension.
- And a third-time DUI carries a three-year-long suspension.
