The Green Bay carrier base in numbers
| Carriers registered locally | 1,482 |

What the local carrier data shows
MCS-150 currency runs well above the national average in this market: 52% of local carriers (773 in total) have not filed inside 24 months, against 38% nationally. Carriers with an overdue MCS-150 should update the filing to keep the registration current.
58% of local carriers run a single power unit and 24 run more than fifty. The federal duties are the same either way, but a one-person operation carries them without a safety office.
The share of newly registered carriers here is below average, at 7% against 12% nationally (106 carriers). New entrant status changes the compliance process: new carriers may be subject to FMCSA’s New Entrant Safety Assurance Program, including a safety audit during the new-entrant period.

DOT compliance questions for Green Bay
What should a Green Bay carrier check before accepting work around Port of Green Bay and Fox River industrial sites?
Confirm the responsible carrier, cargo and commerce, authority and insurance scope, driver status, available hours, exact vehicle configuration, facility access and route requirements before the Green Bay assignment is released.
Does staying near Green Bay make a shipment intrastate?
Not automatically. A Green Bay carrier should review the shipment origin, intended destination and its place in any continuous interstate movement rather than deciding from local mileage alone.
Which records help explain delays on I-41, I-43 and US 141?
For a Green Bay trip, compare dispatch changes, road or facility timestamps, ELD or time records, fuel, inspections and delivery evidence. The records should explain both duty time and equipment custody.
How should vehicle defects be handled in Green Bay?
The Green Bay carrier should identify the unit, defect, person making the out-of-service decision, work performed and authorized return date. Inspect refrigeration-supporting equipment, brakes and tires before peak food movements and retain outside-repair detail.
When is a compliance review useful for a Green Bay fleet?
Arrange a Green Bay review before new entrant activity, after route or fleet growth, when inspection patterns worsen, after a major customer changes the operation, or when required records cannot be retrieved consistently.
