DUI (Driving Under the Influence), DWI (Driving While Intoxicated), or OUI (Operating Under the Influence)—whatever your state calls it, these offenses are serious. Driving under the influence of alcohol is a criminal offense for all drivers, but CDL holders are held to even stricter standards.

What Qualifies as a DUI/DWI?

• For regular drivers, a blood alcohol content (BAC) of 0.08or higher qualifies as DWI.
• For CDL drivers operating a commercial vehicle, a BAC of just 0.04 is enough for a DWI charge.

Even if you don’t feel impaired, the legal limits can result in arrest or conviction.

How DUI/DWI Impacts CDL Drivers

CDL holders face higher stakes:

• A DUI/DWI conviction can lead to license suspension or revocation, threatening your livelihood.
• Employers and insurers take DUI/DWI charges seriously, which can affect your career long-term.
