InactiveDBA: Diamond S Trucking
Schellenberg Enterprises Inc, doing business as Diamond S Trucking, is a registered motor carrier with the FMCSA under USDOT number 691130 and MC number 320392. The company operates from Catoosa, OK, and currently has an inactive operating status, and has 23 power units and 23 drivers on record. Brokers and shippers should verify authority status before tendering loads to inactive carriers.
This USDOT is inactive
FMCSA lists this carrier as inactive, which means it is not currently authorized to operate. Inactive does not mean the carrier never existed or that the historical data on this page is inaccurate. The record stays on USDOTwatch because brokers, insurers, and compliance teams still need to look up historical entities, audit past bookings, and trace predecessor carriers when reviewing related operations. See the methodology for how inactive records are handled.
Is this carrier bookable?
There is a blocking issue on this exact carrier record that should be resolved before booking.
Six things go into this read of Schellenberg Enterprises Inc's record: operating authority, out-of-service status, insurance filings, safety rating, BASIC percentile scores, and MCS-150 freshness. Every one of them comes straight from the public FMCSA record. None of them tell you how the carrier handles damage claims or hits delivery windows, so always pull a fresh insurance certificate from the carrier and confirm rates and contact details on a current rate confirmation before you tender.

Fleet profile
Small fleet (10–99 units)Raw fleet counts only tell you so much about a carrier. A 100-truck fleet with 300 drivers is almost certainly running team or multi-shift over-the-road operations. A 100-truck fleet with 90 drivers is more likely owner-operators, regional, or local work. The ratios below are calculated from FMCSA fleet, mileage, and inspection data and show you how Schellenberg Enterprises Inc actually runs day to day. That helps you judge whether their capacity, utilization, and safety performance match the kind of load you're looking to tender.
Drivers per Power Unit
1.00
Roughly one driver per truck. Typical for regional or local fleets.
Miles per Power Unit

Heavy over-the-road utilization (2022 data).

Insurance history
Every insurance filing FMCSA has on record for Schellenberg Enterprises Inc, up to the 25 most recent including cancelled policies. Each row shows the form type, the insurance company, when the policy went into effect, and when (or if) it was cancelled.

Frequently Asked Questions
Common questions brokers and shippers ask about Schellenberg Enterprises Inc and how to interpret the FMCSA data shown on this page.
What is the USDOT number for Schellenberg Enterprises Inc?
Schellenberg Enterprises Inc is assigned USDOT number 691130 by the Federal Motor Carrier Safety Administration. This number uniquely identifies the carrier in federal safety records and is used to track inspections, crashes, compliance reviews, and operating authority over time.
What is the MC number for Schellenberg Enterprises Inc?
Schellenberg Enterprises Inc's MC number is 320392. The MC (Motor Carrier) number is the operating authority number issued by FMCSA, separate from the USDOT number. It authorizes the carrier to transport regulated commodities for hire in interstate commerce.
Is Schellenberg Enterprises Inc authorized to operate?
Schellenberg Enterprises Inc's current operating status is INACTIVE. They do not currently have a formal safety rating from FMCSA. Always verify operating authority and request a current insurance certificate before tendering loads.
What does it mean that Schellenberg Enterprises Inc is inactive?
An inactive operating status means Schellenberg Enterprises Inc's USDOT registration has lapsed, often because they failed to file the required biennial MCS-150 update or chose to deactivate their authority. Inactive carriers are not currently authorized to operate. Do not tender loads to inactive carriers without first verifying current authority directly with FMCSA.
How many crashes has Schellenberg Enterprises Inc been involved in?
FMCSA records 30 reported crashes for Schellenberg Enterprises Inc over a rolling 24-month window, including 3 fatal, 10 injury, and 30 tow-away crashes. Crash counts include both preventable and non-preventable events. Always evaluate raw counts against fleet size and miles driven.
How large is Schellenberg Enterprises Inc's fleet?
Schellenberg Enterprises Inc operates 23 power units (trucks and tractors) and reports 23 drivers on their FMCSA MCS-150 form. Fleet figures are self-reported and updated biennially, so the live operational fleet may differ slightly.
Where is Schellenberg Enterprises Inc located?
Schellenberg Enterprises Inc is headquartered in Catoosa, Oklahoma at 406 Tigerswitch Road. They operate in interstate commerce across state lines.
What does "Not Rated" mean?
"Not Rated" means FMCSA has not conducted a formal compliance review for this carrier. It does not indicate a safety problem on its own. The vast majority of registered carriers operate without a formal rating because compliance reviews are typically only triggered by elevated risk indicators, complaints, or scheduled audits. Use BASIC scores, inspection history, and crash records to evaluate unrated carriers.
How often is FMCSA data updated?
FMCSA refreshes carrier census data daily. Inspection and crash records are typically published within 30 days of the underlying event. Safety ratings and BASIC scores update on FMCSA's monthly cycle. The "last checked" timestamp at the bottom of this page shows when the most recent FMCSA poll happened.
Should I monitor Schellenberg Enterprises Inc for changes?
If you tender loads to Schellenberg Enterprises Inc regularly, monitoring is worth considering. Operating authority can lapse, insurance can drop, and safety ratings can change between bookings. Email alerts surface those changes the moment FMCSA publishes them, so you find out before your next load instead of after a problem on the road.
Where does this data come from?

It includes the Company Census File, roadside inspection records, crash reports, and SMS/BASIC safety scores. Data is self-reported by carriers and updated regularly by FMCSA.
