A commercial driver driving a commercial vehicle is held to a .04% BAC instead of the normal .08% BAC requirement. The Department of Motor Vehicles will suspend your commercial license for one year without eligibility for a restricted commercial license but you may apply for a Class C restricted license after 30 days of hard suspension. Additionally, even if you are not driving a commercial vehicle but are found to have violated VC 23152 (a) and/or (b), and hold a commercial license, the DMV can suspend your commercial license for one year on a first offense and revoke the privilege for a lifetime on a second offense.
