If you have a CDL and are convicted of DUI, you will lose your CDL in addition to the penalties you will receive under Florida law. This could cost you your living.
If you receive your first DUI conviction while driving a non-commercial vehicle and have a CDL, then you may lose your CDL for a period of one year. A first DUI conviction while driving a commercial vehicle will result in the loss of your CDL for one year if you are transporting hazardous materials that do not require a placard. If the hazardous material needs to carry a placard then you will lose your CDL for three years.
