DOT SAP Evaluation in Iowa — 14 Providers Listed

Iowa's two interstates cross at Des Moines: I-80 east-west and I-35 north-south. Grain, ethanol, hogs and packaged food move out of Des Moines, Cedar Rapids, the Quad Cities, Sioux City and Waterloo, and a large share of the state's CDL holders drive for agricultural and food carriers rather than general freight. We list 14 providers for Iowa on this page, 3 of which say on their own website they perform DOT SAP evaluations, with offices in Coralville, Des Moines and West Des Moines. The other 11 listings are for treatment or testing, which you may need later in the process, not for the evaluation itself.

There is no Iowa version of the SAP process. The return-to-duty steps are federal, set out in 49 CFR Part 40, and they are the same for a driver in Iowa as for one anywhere else. The state's part is the CDL itself. Since November 18, 2024 (FMCSA), the Iowa Department of Transportation must downgrade the license of a driver in prohibited status within 60 days, and it is the office that restores the commercial privilege after a negative return-to-duty test.

A remote evaluation is accepted in Iowa because the federal rule permits it everywhere: a SAP may evaluate you by real-time video at their discretion (49 CFR §40.291), provided their own license lets them see a driver in Iowa. A SAP across the line in Minnesota, Wisconsin, Illinois, Missouri, Nebraska and South Dakota is also an option, in person or by video, under the same licensing question. The one step that always needs a collection site is the observed return-to-duty test; everything up to it can often be done from home.
