DOT Collector Certification in Wisconsin
Complete 2026 Guide — I-94 Milwaukee–Chicago Corridor (Top 10 Highest Commercial Truck Volume Interstate), Enbridge Line 5 PHMSA Corridor, Duluth-Superior Twin Ports (PHMSA + FRA + FMCSA Overlap), and Molson Coors Milwaukee HQ (Highest BAT Demand per Capita in the Midwest)
Quick Answer — DOT Collector Certification in Wisconsin at a Glance
- ▸Federal standard only — no Wisconsin state license required: 49 CFR Part 40 §40.33 is the sole certification framework. The Wisconsin Department of Safety and Professional Services does not regulate DOT urine collectors separately. No state exam, no state registration — one federal credential covers every DOT employer in Wisconsin.
- ▸I-94 Milwaukee–Chicago corridor — top 10 commercial truck volume in the US: The I-94 corridor connecting Milwaukee to the Chicago metro CDL hub is one of the highest-volume commercial trucking interstates in the country, driving consistent FMCSA pre-employment and random testing demand across southeastern Wisconsin.
- ▸Enbridge Line 5 — active PHMSA regulatory topic 2024–2026: The contested pipeline corridor running from Superior, WI through Michigan has kept Wisconsin PHMSA compliance in the spotlight. Pipeline operations, maintenance, and emergency response workers along this corridor are subject to 49 CFR Part 199 testing at 50% drug / 25% alcohol random rates.
- ▸Duluth-Superior twin ports — PHMSA + FRA + FMCSA overlap zone: Superior, WI is the southernmost deepwater Great Lakes port. BNSF and CN rail serve the port. Iron ore, coal, and petroleum product transfer creates a rare three-agency regulatory overlap that supports multi-agency collection volume in a single location.
- ▸Marijuana still ILLEGAL in Wisconsin — lower positive rates than neighboring states: Wisconsin has NOT legalized recreational or medical marijuana as of 2026. DOT drug test positive rates for cannabis in Wisconsin are lower than neighboring Illinois (rec-legal 2020), Minnesota (rec-legal 2023), and Michigan (rec-legal 2018). Federal §40.85 zero-tolerance applies statewide regardless.
- ▸All 5 DOT agencies active: FMCSA (I-94/I-43/I-39 CDL corridors), FRA (CN + BNSF + Wisconsin Central rail), FTA (Milwaukee County Transit System), FAA (General Mitchell International Airport), PHMSA (Enbridge + ANR Pipeline). One §40.33 certificate covers all five.
Wisconsin's DOT collection market is anchored by a geographic and regulatory combination that creates opportunity across all five federal agencies. The I-94 corridor running from Milwaukee south to the Illinois border and the Chicago metro CDL hub is one of the highest commercial truck volume interstate segments in the United States — generating consistent FMCSA pre-employment and random testing demand across southeastern Wisconsin. North of Milwaukee, I-43 connects to Green Bay and the Fox Valley manufacturing corridor. I-39 runs north–south through the middle of the state, linking Madison to Wausau and the northern Wisconsin industrial base.
Wisconsin's PHMSA market is defined by two distinct geographic anchors. Enbridge Line 5 — the contested crude oil and natural gas liquids pipeline that runs from Superior, WI through Michigan's Upper Peninsula — has been an active regulatory controversy since 2021 and has kept Wisconsin PHMSA compliance in the national spotlight through 2026. The Duluth-Superior twin ports on the western tip of Lake Superior represent a different kind of PHMSA opportunity: Superior, WI is the southernmost deepwater Great Lakes port, where BNSF and CN rail transfer iron ore, coal, and petroleum products between modes — creating a rare PHMSA + FRA + FMCSA three-agency overlap zone. Add Molson Coors' Milwaukee headquarters (the largest brewery employer in the US — creating unusually high demand for BAT certification alongside urine collection), Johnson Controls and Oshkosh Corporation CDL fleets, and Wisconsin's still-illegal marijuana status (lower positive rates than neighboring Illinois, Minnesota, and Michigan), and Wisconsin presents a market with several genuinely distinctive angles.
Why Wisconsin Is a High-Value DOT Collection Market
The I-94 Milwaukee–Chicago corridor ranks among the top 10 highest commercial truck volume interstate segments in the United States. Milwaukee sits at the junction of I-94, I-43, and I-894, creating a dense CDL employer cluster that generates consistent FMCSA pre-employment, random, and post-accident testing demand year-round.
Enbridge Line 5 runs from Superior, WI through Michigan's Upper Peninsula — an active PHMSA regulatory topic since 2021. Pipeline operations, maintenance, and emergency response workers along this Wisconsin corridor are subject to 49 CFR Part 199 testing at the highest alcohol random rate of any DOT agency: 25%.
Superior, WI is the southernmost deepwater port on the Great Lakes. BNSF and CN rail serve the Duluth-Superior port complex. Iron ore, coal, and petroleum product transfer creates a PHMSA + FRA + FMCSA three-agency overlap — allowing collectors to serve multiple regulatory frameworks from a single geographic location.
Wisconsin's CDL workforce is concentrated along the I-94 Milwaukee–Chicago corridor and in the Fox Valley (Green Bay/Appleton) manufacturing region. Major employers include Oshkosh Corporation, Johnson Controls, Harley-Davidson, Kwik Trip, Schneider National (Green Bay), and Uline (Pleasant Prairie) — all with FMCSA-regulated fleets.
Molson Coors Beverage Company is headquartered in Milwaukee — the largest brewery employer in the United States. DOT alcohol testing (§40.251 EBT) is a live topic in a city where the dominant employer is a brewery. BAT (Breath Alcohol Technician) certification demand in Milwaukee is higher than in almost any comparable metro.
One §40.33 certificate qualifies you to collect for FMCSA, FRA, FTA, FAA, and PHMSA employers — all active across Wisconsin's freight, rail, transit, aviation, and pipeline industries.
Federal Standard vs. Wisconsin-Specific Context
DOT collector certification in Wisconsin is governed entirely by federal law. There is no Wisconsin-specific licensing layer, no state exam, and no state registration. Here is what the federal standard requires and what Wisconsin adds — which is nothing beyond the federal floor.
- ✓§40.33(b) training — study of procedures, errors, and correction protocols
- ✓Mock collection proficiency — 5 collections (3 standard, 1 observed, 1 shy bladder)
- ✓Observed collection training — §40.67 same-sex observer requirement
- ✓Federal Custody and Control Form (CCF) — required for every specimen
- ✓SAMHSA-certified laboratory requirement for all DOT specimens
- ✓§40.33(c) error correction training if a fatal or correctable error occurs
- →No Wisconsin state license required — §40.33 federal certification is the only credential needed
- →Wisconsin DSPS does NOT regulate DOT urine collectors separately from federal requirements
- →Wisconsin has NOT legalized recreational or medical marijuana — federal §40.85 and state law are in agreement (unlike neighboring IL, MN, MI)
- →Wisconsin adds ZERO state requirements on top of 49 CFR Part 40 — federal floor only
- →No additional state permit required for mobile collectors operating statewide
- →One federal certification covers Milwaukee, Madison, Green Bay, Kenosha, Racine, and all Wisconsin markets
How to Become a DOT Collector in Wisconsin — Step by Step
Complete §40.33(b) Training
Enroll in an online or in-person §40.33 training course. The curriculum covers collection procedures, the Federal Custody and Control Form (CCF), specimen integrity requirements (§40.91), observed collections (§40.67), shy bladder protocol (§40.193), and error correction procedures. Cedar & Crown's online course covers all required §40.33 content in approximately 4–8 hours and can be completed from anywhere in Wisconsin.
Perform 5 Mock Collections
Before performing actual DOT collections, §40.33(b) requires 5 mock collections: 3 standard collections, 1 observed collection, and 1 shy bladder scenario. Mock collections are performed with a trainer or qualified observer. Most Wisconsin students complete all 5 in a single 2–4 hour session — either in-person with a local trainer or via a structured remote mock collection program.
Acquire DOT Collection Supplies
You will need: Federal Custody and Control Forms (CCF), DOT-approved specimen cups with temperature strips, tamper-evident bottle seals, blue dye for toilet water, and a thermometer. A complete starter kit costs $100–$165 and covers your first 25+ collections. Milwaukee and Madison occupational health supply vendors and online distributors can fulfill orders quickly.
Join a C/TPA Network or Contract Directly
Most Wisconsin collectors start by joining a C/TPA dispatch network. National Referral, CRL (Compliance Resources & Lab), Workplace Solutions, and First Advantage all operate in Wisconsin — with the strongest dispatch density in the Milwaukee and Madison metros. Direct outreach to I-94 corridor trucking fleets (FMCSA), Schneider National or other Green Bay-area carriers (FMCSA), CN or BNSF rail contractors in the Superior port area (FRA), Milwaukee County Transit System vendors (FTA), and Enbridge pipeline contractors in northern Wisconsin (PHMSA) builds multi-agency volume.
Maintain Proficiency — §40.33(c) Error Correction
If you make a fatal or correctable CCF error, §40.33(c) requires completing error correction training before performing another collection in that category. Strict adherence to the 8-step collection procedure (§40.61–§40.73) and accurate CCF completion minimizes error risk and protects your collection business.
Wisconsin's DOT Agency Landscape — All 5 Agencies Active
Wisconsin's freight corridors, rail network, port complex, transit systems, and pipeline infrastructure means all five DOT modal agencies have active employer footprints in the state. One §40.33 certificate covers every employer type — from I-94 CDL freight to BNSF rail to Milwaukee County Transit to Enbridge pipeline operations.
Trucking — FMCSA
Wisconsin's ~500,000 CDL holders are concentrated along three major corridors: I-94 (Milwaukee to the Illinois border and the Chicago metro CDL hub — top 10 US commercial truck volume), I-43 (Milwaukee north to Green Bay and the Fox Valley manufacturing region), and I-39 (Madison north through Wausau). Major FMCSA employers include Schneider National (headquartered in Green Bay — one of the largest US trucking companies), Kwik Trip (La Crosse — large private fleet), Uline (Pleasant Prairie, near Kenosha — massive distribution operation), Oshkosh Corporation, Johnson Controls, and Harley-Davidson, all of which maintain CDL-regulated fleets for parts logistics and vehicle transport.
Rail — FRA
Wisconsin is served by three Class I railroads: CN (Canadian National), BNSF, and Wisconsin Central (owned by CN). CN's Chicago–Milwaukee–Green Bay corridor is a major freight line with locomotive engineers, conductors, and maintenance-of-way workers subject to FRA Part 219 drug and alcohol testing at 25%/10% random rates — including the FRA's expanded 10-panel drug test. In the Duluth-Superior area, both BNSF and CN operate extensive rail yards transferring iron ore, grain, and petroleum products to Great Lakes vessels — with concentrated FRA testing demand at the port terminals. Wisconsin Central serves paper mill and industrial sites throughout northern and central Wisconsin.
Transit — FTA
Milwaukee County Transit System (MCTS) is Wisconsin's largest FTA-covered transit agency — operating approximately 300 fixed-route buses and employing safety-sensitive bus operators, mechanics, and dispatchers subject to FTA Part 655's 50%/10% random testing rates. Madison Metro Transit, Green Bay Metro, La Crosse Transit, Appleton Transit, and other municipal systems add FTA-covered workers across Wisconsin's secondary markets. University of Wisconsin campus transportation systems in Madison and Milwaukee may also have FTA-covered operations depending on federal funding status.
Aviation — FAA
General Mitchell International Airport (now officially Milwaukee Mitchell International Airport) is Wisconsin's primary commercial airport, with American, Delta, Frontier, Southwest, and United operations employing ramp agents, aircraft maintenance technicians, and airline ground operations workers subject to FAA Part 120 safety-sensitive classification. Austin Straubel International Airport in Green Bay and Dane County Regional Airport in Madison serve regional airline operations with additional FAA-covered maintenance and ground workers. Air cargo operations at Mitchell International — including FedEx Express and UPS Air — add FMCSA and FAA dual-coverage for ramp and ground vehicle operators.
Pipeline — PHMSA
Wisconsin's PHMSA market is anchored by two major operators. Enbridge Inc. operates the Line 5 pipeline corridor from Superior, WI — a crude oil and natural gas liquids line that has been an active regulatory controversy since 2021. Pipeline operations, maintenance, emergency response, and control room workers along this corridor are subject to PHMSA Part 199 at the highest alcohol random rate of any DOT agency: 25%. ANR Pipeline (TransCanada) operates natural gas transmission infrastructure across Wisconsin's southern tier. WPS (Wisconsin Public Service) and WE Energies also employ PHMSA-covered workers in natural gas distribution operations throughout the state. PHMSA's 25% alcohol random rate — versus 10% for FMCSA — makes pipeline accounts high-frequency and high-value.
One §40.33 Certificate Covers Every Wisconsin Agency — FMCSA, FRA, FTA, FAA, and PHMSA
I-94 CDL freight, Schneider National carrier fleets, CN rail yard workers at the Duluth-Superior port, Milwaukee County Transit operators, Mitchell International maintenance crews, and Enbridge pipeline technicians in northern Wisconsin — all require DOT collections, all covered by one federal certification. Cedar & Crown's $99 course qualifies you to collect across Wisconsin's entire DOT-regulated workforce.
Get Certified for $99C/TPA Networks in Wisconsin — How to Get on the Dispatch Lists
Getting your §40.33 certification is step one. Getting your first paying collection is step two — and in Wisconsin, the fastest path starts with C/TPA network applications, followed by direct outreach to I-94 corridor trucking employers, CN and BNSF rail contractors, and Milwaukee County Transit vendors.
National Referral
One of the largest collector dispatch networks serving the upper Midwest. National Referral operates across the Milwaukee and Madison metros and secondary Wisconsin markets, dispatching certified collectors for FMCSA, FRA, FTA, and FAA employer accounts. High dispatch volume along the I-94 Milwaukee–Chicago corridor makes this a strong first network for southeastern Wisconsin collectors.
CRL (Compliance Resources & Lab)
CRL operates in Wisconsin with a focus on trucking and industrial employer accounts. Their collector network covers the Milwaukee and Green Bay metros and extends to Madison, Kenosha, and Racine. Strong for FMCSA pre-employment demand tied to Wisconsin's I-94 corridor CDL workforce and Fox Valley manufacturing fleets.
Workplace Solutions
Workplace Solutions provides drug and alcohol testing program management for mid-sized employers across Wisconsin — particularly in Milwaukee, Madison, and the Fox Valley (Green Bay/Appleton/Oshkosh). Their preferred collector program covers both clinic-based and mobile collections statewide, with good penetration into Wisconsin's manufacturing sector.
First Advantage
First Advantage operates background screening and drug testing programs nationally, with strong employer account density in Wisconsin's manufacturing, logistics, and transportation sectors. Collectors on First Advantage's preferred vendor list receive dispatch for large-employer accounts tied to Wisconsin's industrial base — Oshkosh Corporation, Johnson Controls, Harley-Davidson, and the Fox Valley paper and packaging manufacturing corridor.

Part-Time Annual Volume Math
Milwaukee collectors can combine I-94 corridor FMCSA accounts, MCTS transit vendor collections (FTA), Mitchell International cargo ramp operators (FAA), and WE Energies or Wisconsin Gas pipeline accounts (PHMSA) into a multi-agency account base within the metro. The I-94 corridor between Milwaukee and Kenosha offers the highest CDL employer density per mile of any Wisconsin highway segment — strong for mobile collectors working the corridor.
Wisconsin Deep Dive — The Angles That Define the Collection Opportunity
Enbridge Line 5 — Active PHMSA Regulatory Topic Through 2026
Enbridge Line 5 is a dual 20-inch crude oil and natural gas liquids pipeline that originates at Superior, Wisconsin — the southernmost deepwater port on the Great Lakes — and runs approximately 645 miles through Michigan's Upper Peninsula before crossing the Straits of Mackinac to Sarnia, Ontario. The Wisconsin segment of Line 5 and its contested extension route have been active PHMSA regulatory topics since 2021, when Michigan's governor revoked the pipeline easement in the Straits of Mackinac. While the legal and regulatory dispute has focused on the Michigan crossing, the Wisconsin portion of the pipeline system continues to operate, employing pipeline operations, maintenance, emergency response, and control room workers subject to PHMSA 49 CFR Part 199 drug and alcohol testing.
For Wisconsin PHMSA collectors, Line 5 represents an ongoing regulatory story with direct implications for the collection market. PHMSA's heightened oversight of the Line 5 corridor — including potential reroute projects through northern Wisconsin — could increase the pipeline workforce and testing demand in the Superior and northern Wisconsin market. Any Wisconsin collector working with Enbridge contractors, terminal operators, or pipeline maintenance companies in the Superior area should understand the Line 5 regulatory context and the broader Enbridge Wisconsin asset base.
PHMSA Part 199 carries the highest alcohol random testing rate of any DOT agency — 25% annually, compared to 10% for FMCSA and FTA. Pipeline employers test at 50% drug / 25% alcohol random rates, making them high-frequency collection accounts. Wisconsin's PHMSA market extends beyond Line 5: ANR Pipeline (TransCanada), Wisconsin Public Service (WPS), and WE Energies all operate PHMSA-covered natural gas infrastructure across the state.
Duluth-Superior Twin Ports — PHMSA + FRA + FMCSA Three-Agency Overlap Zone
Superior, Wisconsin forms one half of the Duluth-Superior twin ports at the western tip of Lake Superior — the southernmost deepwater port on the Great Lakes system and the third-largest port in the United States by tonnage in many years. The port handles iron ore, coal, grain, limestone, and petroleum products transferred between Great Lakes vessels, rail cars, and over-the-road trucks. This multi-modal transfer operation creates one of the most distinctive DOT regulatory overlap zones in the Midwest.
BNSF Railway and CN (Canadian National) both operate extensive rail yards in the Duluth-Superior port complex, employing locomotive engineers, conductors, trainmen, and maintenance-of-way workers subject to FRA Part 219 drug and alcohol testing — including FRA's expanded 10-panel drug test (which differs from the standard FMCSA 5-panel). The petroleum product transfer operations at the port involve PHMSA-covered workers handling crude oil and refined product loading and transfer. CDL truck drivers hauling iron ore concentrate, coal, or petroleum products from the port terminals fall under FMCSA Part 382.
For a Wisconsin DOT collector operating in or near Superior, the Duluth-Superior port complex offers a rare opportunity to serve three distinct regulatory agencies — PHMSA, FRA, and FMCSA — from a single geographic location. The key difference to understand is the drug panel: FRA-covered workers are tested under a 10-panel extended panel, while FMCSA- and PHMSA-covered workers use the standard 5-panel. The collection procedure under 49 CFR Part 40 is identical regardless of the panel — but the CCF and laboratory requisition must reflect the correct testing authority.
I-94 Milwaukee–Chicago Corridor — Top 10 Commercial Truck Volume Interstate in the US
The I-94 corridor connecting Milwaukee to the Illinois state line and the Chicago metro CDL hub is one of the top 10 highest commercial truck volume interstate segments in the United States. The Milwaukee–Chicago corridor functions as the primary freight artery linking Wisconsin's manufacturing and distribution economy to the Chicago area's massive logistics infrastructure — the second-largest inland distribution hub in North America. Every commercial motor vehicle operator on this corridor is subject to FMCSA 49 CFR Part 382 drug and alcohol testing requirements.
For DOT collectors, the I-94 corridor generates consistent FMCSA pre-employment, random, post-accident, and reasonable suspicion testing demand year-round. The density of CDL employers along the corridor — distribution centers in the Kenosha/Pleasant Prairie/Racine area, manufacturing plants in the Milwaukee metro, and logistics hubs serving the Chicago market — creates a mobile collector route that can sustain high weekly collection volumes without long drive times between accounts.
Key I-94 corridor employers include: Uline (Pleasant Prairie — one of the largest private fleet distributors in the US, with hundreds of company CDL drivers), Amazon fulfillment centers in Kenosha and Milwaukee, SC Johnson (Racine — large corporate CDL fleet), Harley-Davidson (Milwaukee — significant CDL parts logistics fleet), and Johnson Controls (Milwaukee — global CDL fleet for facility services and vehicle transport). The I-94 corridor between Kenosha and Milwaukee is arguably Wisconsin's highest-value single geographic segment for mobile DOT collectors.
Wisconsin Marijuana Status — Still Illegal as of 2026 (A Differentiating Market Angle)
Wisconsin is one of the few remaining Midwestern states that has NOT legalized recreational or medical marijuana as of 2026. Multiple legislative efforts — including a notable April 2024 push — have failed to pass. This stands in contrast to neighboring states: Illinois legalized recreational marijuana in January 2020, Minnesota legalized recreational marijuana in August 2023, and Michigan legalized recreational marijuana in December 2018. Wisconsin's prohibition status means the state does not have a population of state-legally protected cannabis users normalizing recreational use — and Wisconsin's DOT drug test positive rates for cannabis are measurably lower than neighboring states as a result.
The table below shows how Wisconsin's state law and federal §40.85 compare — and why the columns agree, unlike most neighboring states:
| Regulatory Layer | Wisconsin State Law (2026) | Federal §40.85 (DOT) |
|---|---|---|
| Recreational Cannabis | ILLEGAL | PROHIBITED (zero tolerance) |
| Medical Cannabis | ILLEGAL (no medical program) | PROHIBITED (no medical exception) |
| DOT Positive Consequence | State criminal exposure possible | Clearinghouse prohibited status, removal from safety-sensitive duty |
| vs. Neighboring IL/MN | WI state law = stricter than IL/MN | Federal overrides state regardless — IL/MN rec-legal status irrelevant for CDL drivers |
Collectors serving employers in the Milwaukee and Kenosha/Racine corridor — especially employers whose workforce includes cross-border commuters from Illinois — should be aware that Illinois' recreational cannabis legalization (2020) has created behavioral normalization among some workers who may not fully understand that the federal §40.85 zero-tolerance standard applies to all DOT safety-sensitive employees regardless of which side of the state line they live on.
Molson Coors Milwaukee HQ — Highest BAT Demand per Capita in the Midwest
Molson Coors Beverage Company is headquartered in Milwaukee, Wisconsin, and operates the Miller Valley brewery complex — making Milwaukee home to one of the largest single-employer brewery workforces in the United States. This creates a collection market angle that is unique among US metros: DOT alcohol testing (§40.251 Evidential Breath Testing) is a live and frequent topic in a city where the dominant large employer is a brewery.
The practical implication for Wisconsin DOT collectors is that BAT (Breath Alcohol Technician) certification demand in Milwaukee is higher than in almost any comparable metro. CDL drivers operating beer distribution trucks, material handling workers on the brewery floor, and logistics contractors serving the Molson Coors distribution network are all subject to FMCSA Part 382 drug and alcohol testing. The alcohol-testing component — requiring EBT (Evidential Breath Test) administration by a qualified BAT or STT — is not covered by the standard urine collection §40.33 credential. Collectors who add BAT certification to their §40.33 credential are positioned to serve the full range of DOT testing demand at Milwaukee alcohol-adjacent employers.
Beyond Molson Coors, Milwaukee's broader manufacturing and logistics base includes Harley-Davidson (motorcycle assembly plant with large CDL fleet), Johnson Controls (global operations headquarters with Wisconsin-based CDL logistics), Milwaukee Tool (Brookfield — distribution CDL fleet), and a dense cluster of third-party logistics (3PL) operators serving the Milwaukee metro. These employers generate consistent FMCSA pre-employment and random testing demand that supports both clinic-based and mobile collection operations.
Johnson Controls / Oshkosh Corporation / Harley-Davidson — Wisconsin Industrial CDL Fleet Demand
Wisconsin's major industrial employers all maintain large CDL fleets for parts logistics, vehicle transport, and distribution operations — making them consistent FMCSA testing accounts regardless of economic cycles. Three employers stand out for scale and geographic spread:
- Johnson Controls (Milwaukee / Glendale): Global operations headquarters in Milwaukee with facility services, HVAC, and battery manufacturing operations requiring extensive CDL vehicle fleets. Johnson Controls operates one of the largest corporate CDL fleets in Wisconsin for parts transport, service vehicle operations, and distribution logistics. Consistent FMCSA pre-employment testing demand tied to hiring cycles for field service technicians and logistics drivers.
- Oshkosh Corporation (Oshkosh): Manufactures specialty vehicles including military vehicles (JLTV, HEMTT), refuse trucks (McNeilus), aerial work platforms (JLG), and concrete mixers (London). Oshkosh's Oshkosh, Wisconsin manufacturing complex employs hundreds of CDL operators for vehicle transport and parts logistics. The I-41 corridor north from Milwaukee to Green Bay/Oshkosh is a significant FMCSA collection corridor tied to Oshkosh Corporation and its supplier network.
- Harley-Davidson (Milwaukee / Menomonee Falls): The iconic motorcycle manufacturer operates assembly plants and a powertrain facility in the Milwaukee metro, with a significant CDL parts logistics fleet serving the manufacturing supply chain. Harley-Davidson's Milwaukee operations generate consistent FMCSA pre-employment testing demand tied to manufacturing hiring cycles, and the company's large hourly workforce creates ongoing random testing volume.
These three employers — combined with Uline (Kenosha), Kwik Trip (La Crosse), SC Johnson (Racine), Schneider National (Green Bay), and the Fox Valley paper manufacturing corridor — give Wisconsin collectors a diverse FMCSA account base that is not dominated by any single industry sector.
