Commercial Driver DUI Laws in Iowa

What are commercial driver DUI laws, and how do they apply in Iowa?

In Iowa, a person may be charged with Driving Under the Influence (DUI) for operating a commercial vehicle while under the influence of alcohol or drugs. If convicted, the penalties are more severe than those for operating a non-commercial vehicle. Commercial drivers in Iowa are subject to the same DUI laws as non-commercial drivers. The legal limit for DUI is 0.08 Blood Alcohol Content (BAC). If a driver’s BAC exceeds the legal limit, they are considered to be driving under the influence and may face criminal charges.

Penalties for a first-time DUI conviction can include a fine, license suspension, jail time, and/or community service. Additionally, drivers who are convicted of a DUI will be punished with a one-year disqualification of their commercial driver’s license (CDL). They will also be required to undergo an alcohol/drug abuse treatment program and will be placed on probation for three years.

Commercial drivers who refuse to take a breath or blood test when suspected of DUI will also face severe penalties. This includes an automatic one-year disqualification of their CDL, even if they are not charged or convicted of DUI.

In Iowa, it is illegal for commercial drivers to have any detectable amount of alcohol in their system while operating a commercial vehicle. If a police officer suspects that a commercial driver has been drinking, they may ask them to submit to an alcohol test. Refusal to take the test can result in automatic suspension of their CDL.

As a result, CDL holders can be arrested and charged with DUI/DWI at lower BAC levels than non-commercial drivers in Iowa.
