DUI Legal Limit for CDL Drivers Bubba Head

What is the legal DUI limit for CDL drivers?

The legal BAC limit for CDL drivers in Georgia is .o4%. Federal law dictates that a CMV operator found with ANY trace of alcohol on his or her breath will have that vehicle taken off the road for the next 24 hours. This is how strict the CMV laws are, due to the high incidence of deaths and serious bodily injury when a 40,000 pound (or more) vehicle collides with a passenger car or pickup truck.

Additionally, all states define a permissible legal alcohol limit for drivers of commercial motor vehicles, which does not only mean drivers of tractor-trailer rigs. School buses and any transport van that has seats for 16 or more people are typically a CMV (commercial motor vehicle), under state DUI laws.

These high-risk vehicles, due to size and weight or due to exposure to multiple injuries or fatalities, are covered by federally-controlled commercial motor vehicle laws.

Federal laws controlling interstate commerce have mandated that all states place a legal BAC alcohol limit for CMV drivers at 0.04% when driving such a commercial vehicle. This applies to any commercial driver’s license holder, regardless of age, when he or she is operating a commercial motor vehicle. These drivers are not held to that lower BAC level if they are operating a non-commercial motor vehicle. In these situations, the legal blood alcohol is determined by age of the driver, for adults age 21 and over and under age DUI at 0.00, 0.01 or 0.02 grams percent.

Use the following BAC calculator to determine your blood alcohol content for a person with a commercial driver’s license. When using this BAC chart, refer to the pictures below that show how much alcohol is contained in an average drink.

But a police officer from the Georgia State Patrol or your local DUI Task Force can still arrest you for illegal drinking and driving even if your blood alcohol number is below 0.04.
