Commercial or CDL DUI in California

What is a CDL or commercial DUI in CA?

CDL/Commerical DUI

BAC 0.04% or higher
(half of the normal BAC limit of 0.08%)

An individual arrested for commercial DUI faces the same DUI penalties as any other driver. The difference is that the legal limit for blood alcohol concentration (BAC) for a person operating a commercial vehicle is half the 0.08% of a non-commercial driver.   You can be arrested for commercial DUI if your BAC is 0.04% or higher.  Because commercial drivers are often operating very large vehicles such as a school bus, big rig or semi truck, etc. which can cause extensive injury or death in the event of an accident involving DUI , the law has very little leeway when it comes to commercial drunk driving.

What's different about the penalties for a commercial or CDL DUI conviction?

The penalties for a commercial DUI are the same as those of any other drunk driver conviction.  The only added penalty is, of course, revocation or suspension of your commercial driver's license.  A first conviction for DUI is usually classified as a misdemeanor and carries up to $1000 in fines and fees and 2 days to 6 months in jail.  DUI involving injury or death is a felony offense and the penalties are much higher.
