How OWI cases work in Delavan
Delavan sits at the I-43 / Highway 50 interchange, which is the primary east-west route between Milwaukee and Beloit and a major freight corridor. Wisconsin State Patrol concentrates I-43 enforcement here, and a meaningful share of Delavan OWI cases involve commercial drivers who are cited in personal vehicles but face CDL consequences anyway under federal law.
Under 49 CFR Part 383.51, a CDL holder convicted of OWI in any vehicle (commercial or personal) faces 1-year CDL disqualification on the first qualifying offense and lifetime disqualification on the second. Wisconsin reports the conviction to FMCSA, which propagates the disqualification across state lines. A Delavan OWI in a personal pickup truck can end a Delavan resident's commercial driving career.
Delavan Lake also generates summer OWI activity, including boat OWI cases under § 30.681. Cases from any Delavan arrest are prosecuted in the Walworth County Circuit Court in Elkhorn.
Delavan's I-43 corridor and Delavan Lake recreation pull a meaningful out-of-state share of summer arrests. Northern Illinois drivers heading north for resort weekends and Milwaukee-area drivers heading south to lake destinations both pass through Delavan, and the Wisconsin State Patrol I-43 enforcement segment runs without break between Beloit and Milwaukee. For Illinois residents, Wisconsin reports the OWI conviction back through the federal National Driver Register (Wisconsin is not a Driver License Compact member, but reports through the federal NDR/PDPS system that every state DMV queries), which triggers Illinois statutory summary suspension and SR-22 reporting independent of the Wisconsin sentence.

Defense angles specific to Delavan cases
- CDL preservation is the primary defense priority for Delavan-arrested CDL holders. Reduction to a non-OWI disposition (reckless driving, inattentive driving) preserves the CDL.
- I-43 stops typically rest on a minor traffic-violation predicate captured on State Patrol dash cam. Reasonable-suspicion challenges live here.
- Delavan Lake boat-OWI cross-counting under § 343.307 must be tested against the underlying citation: not every watercraft citation is a § 30.681 OWI.

Frequently asked questions: Delavan OWI
- I have a CDL but I was driving my personal car when I was stopped on I-43. Does the OWI affect my CDL?
- Yes. Under federal law (49 CFR Part 383.51), a CDL holder convicted of OWI in any vehicle, commercial or personal, faces 1-year CDL disqualification on the first qualifying offense and lifetime disqualification on the second. Wisconsin reports the conviction to the FMCSA Commercial Driver License Information System (CDLIS), and the disqualification follows the driver across state lines. CDL preservation through plea negotiation or charge reduction is the priority on day one.
- Where will my Delavan OWI case be heard?
- At the Walworth County Circuit Court, 1800 County Road NN, Elkhorn. Every Walworth County state-court OWI is prosecuted there.
- I am from Illinois and got an OWI on I-43 in Delavan. Will Illinois apply its own consequences?
- Yes. Wisconsin reports OWI convictions to the federal National Driver Register, which the Illinois Secretary of State queries (Wisconsin is one of five states that has not formally joined the Driver License Compact, but the federal NDR/PDPS reporting reach is the same). Wisconsin reports the OWI conviction to the Illinois Secretary of State, which applies its own DUI penalties: statutory summary suspension, points on your Illinois driving record, and SR-22 insurance reporting. The Wisconsin conviction triggers two-state consequences. We coordinate the plea posture with Illinois counsel when the two-state exposure is material.
- I got a boat OWI on Delavan Lake. Will it hurt me later if I get a car OWI?
- Yes. Under Wis. Stat. § 343.307, a § 30.681 boat OWI conviction cross-counts as a prior for vehicle OWI charging. A 1st-offense civil-forfeiture boat OWI on Delavan Lake can elevate a future Highway 50 or I-43 vehicle OWI to a 2nd-offense criminal misdemeanor with mandatory 5 days jail, IID, and 12 to 18 months license revocation. We test whether the prior was actually a § 30.681 conviction (not a watercraft-equipment forfeiture, which does not cross-count).
