How Will an Iowa OWI Conviction Affect My Commercial Driver’s License (CDL)?

Commercial vehicles include most trucks (including tractor-trailer combinations) that weigh more than 26,000 pounds, buses that can carry 16 or more occupants, and vehicles that carry certain hazardous materials.

Every state prohibits driving under the influence (DUI) of alcohol or drugs. While Iowa’s law is often referred to as “operating while intoxicated” (OWI), proof of intoxication is not required. It is enough to prove that the ability to drive safely is impaired by alcohol or drugs, or that a driver’s blood alcohol concentration (BAC) exceeds the legal limit.

Legal Limit for Commercial Drivers

In Iowa and all other states, it is unlawful for any driver to operate a vehicle if the driver’s BAC is at or above 0.08. That BAC is the “legal limit” for most adult drivers.

A lower limit applies when a driver is operating a commercial vehicle. Drivers may not lawfully operate a commercial vehicle with a BAC of 0.04 or more. In addition, it is unlawful to operate a commercial vehicle while under the influence of any drug. The mere presence of certain drugs in a commercial driver’s blood also violates Iowa law.

Impact of OWI Conviction on CDL

A commercial driver faces the same potential penalties for an OWI conviction as any other driver, including a fine and a sentence of incarceration. The consequences for driving status, however, are more severe for commercial drivers.

A commercial driver must have a commercial driver’s license (CDL). While the suspension of regular operating privileges might only last for 6 months following a first OWI conviction, the conviction will cause a one-year disqualification of CDL privileges. The disqualification applies even if the driver was not driving a commercial vehicle when the violation occurred.

A first offense OWI conviction while driving a vehicle with a hazardous waste placard results in a three-year revocation of CDL privileges. Refusing a chemical test of the driver’s breath or blood will have the same consequences for CDL status as an OWI conviction.

A second or subsequent OWI conviction or chemical test refusal at any time will result in a lifetime disqualification. A driver with a lifetime disqualification might be eligible for reinstatement after 10 years, but eligibility will depend on the driver’s completion of an approved rehabilitation program.

Challenging OWI Arrests

Even a one-year disqualification for a first offense OWI will cause most drivers to lose their jobs. While a lifetime disqualification will end a commercial driving career, any OWI conviction might make employers reluctant to hire a driver, even after the disqualification ends.

Disqualifications cannot be negotiated. Prosecutors are powerless to change them. The only way to avoid a disqualification is to avoid a conviction. In cases alleging test refusals, drivers can also avoid disqualification by establishing that no refusal occurred or that the failure to provide an adequate test sample was justified.

Experienced DUI lawyers can assert a variety of challenges to the validity of OWI arrests. We also know how to challenge the evidence of guilt that the prosecution will present at trial. Any driver who has a CDL should obtain immediate legal advice after an Iowa arrest for OWI.
