Detroit employers with CDL drivers covered by Part 382 need to complete the required FMCSA Drug and Alcohol Clearinghouse queries, make required reports and prevent drivers in prohibited status from performing safety-sensitive functions. This can affect car haulers, towing companies, drive-away operations, passenger carriers and other local employers. A provider can act as your designated consortium/third-party administrator (C/TPA) for permitted functions, manage parts of the testing program or review your existing setup.

Part-time, on-call and occasional CDL drivers
Detroit’s carrier records include motor-vehicle, drive-away/towaway and other operations that may use drivers on different work patterns. Part 382 does not create a lower Clearinghouse standard simply because a covered CDL driver works part time or drives only occasionally.
A covered prospective driver needs a full pre-employment query before being employed in a safety-sensitive position. A current covered driver must be queried at least once every 12 months. For employers with drivers who work infrequently, the practical problem is making sure nobody falls outside the annual-query schedule.
Our carrier directory lists about 3,990 carrier records with a Detroit address. About 2,290 show a single power unit, and a one-truck operator who employs himself or herself as a CDL driver must designate a C/TPA in the Clearinghouse. About 520 Detroit records first registered with FMCSA in 2025 or later.
Passenger operations
About 245 Detroit records show passenger vehicles. That includes a mix of passenger operations, but the Clearinghouse rule turns on whether the employer and driver are subject to Part 382, not on whether the vehicle carries freight or passengers.
A passenger employer with covered CDL drivers therefore needs the same core controls: the required pre-employment and annual queries, an active drug and alcohol testing program, required Clearinghouse reporting, and procedures for removing a driver from safety-sensitive work when required.
The employer’s Clearinghouse duties
- Register for the Clearinghouse and obtain the appropriate query plan
- Complete a full pre-employment query before employing a covered driver in a safety-sensitive position
- Query each covered driver at least once every 12 months; a limited query can satisfy the annual requirement when the required general consent has been obtained
- If a limited query shows information exists, obtain the required full query within 24 hours and follow the restrictions that apply until the full query is completed
- Make the reports assigned to employers under the Clearinghouse rules, including applicable refusals and actual-knowledge violations
- Retain limited-query consent records for three years
- Keep a driver in prohibited status out of safety-sensitive functions until the applicable return-to-duty requirements are satisfied
An owner-operator who employs himself or herself as a CDL driver must designate a C/TPA. The designated C/TPA is responsible for the required reporting of the owner-operator’s own violations and can also perform other authorized Clearinghouse functions.
A driver completing the return-to-duty process must work with a qualified SAP and meet the requirements of Part 40 before returning to safety-sensitive functions. The DOT SAP program nationally explains the steps.
Questions for a Detroit provider
Ask exactly which parts of the program the provider will administer. That may include Clearinghouse queries, required reporting, random testing administration, collection-site coordination and follow-up testing. For employers using part-time or on-call drivers, ask how annual query deadlines are tracked.
If testing is included, confirm collection-site coverage around Detroit and Wayne County. If you want driver files, logs and maintenance checked too, book mock DOT audit help in Detroit.

A mock DOT audit in Detroit is an independent review of the safety records and compliance controls that apply to your operation. It gives you a chance to identify incomplete driver files, hours of service problems, testing gaps or maintenance-record issues before an FMCSA or state review. For Detroit carriers, the scope may also need to account for vehicle transport, drive-away operations and freight moving between Michigan and Ontario.
Detroit vehicle transport has its own audit points
Motor vehicles rank second among the top cargo types in Detroit’s carrier records, behind general freight, and drive-away/towaway also appears in the data. Our carrier directory lists about 3,990 carrier records with a Detroit address, including about 2,460 marked for-hire.
For companies moving vehicles or supporting the automotive supply chain, a mock audit should be built around the work actually performed. Relevant areas can include:
- Car haulers: applicable vehicle cargo-securement requirements, driver records, hours of service and inspection and maintenance records
- Drive-away/towaway operations: driver qualification and hours of service records where the FMCSRs apply, plus Part 382 testing when the driver operates a vehicle requiring a CDL
- Towing companies: applicable qualification, hours of service, inspection, maintenance and testing requirements
- Household goods movers: federal safety requirements plus the additional consumer-protection rules that apply to interstate household goods transportation
The provider should distinguish between requirements that apply to every vehicle or driver in scope and requirements triggered by a particular vehicle, CDL status, operating authority or type of transportation.
Local operation can still involve interstate commerce
About 3,160 Detroit records in our directory are marked intrastate-only and about 820 are marked interstate. Those classifications are useful, but the work being performed still matters.
A trip from Detroit into Windsor is international commerce. Transportation entirely within Michigan can also be interstate commerce when it is a leg of an ongoing interstate or international movement, such as cargo moving to or from another state or country. A mock audit should therefore compare the company’s registration and compliance program with its actual routes and freight movements.
About 2,290 Detroit records show a single power unit, and about 520 first registered with FMCSA in 2025 or later. A recent FMCSA registration does not by itself prove that every carrier is in the federal New Entrant program. For carriers that are subject to that program, FMCSA generally conducts the Safety Audit within 12 months after operations begin.
A mock audit is not an FMCSA audit. It produces no federal safety rating or certificate, does not guarantee the result of a later investigation and does not replace a required New Entrant Safety Audit or compliance investigation.
What to prepare and what to ask
Start with the records relevant to your operation. These commonly include USDOT information, operating authority and financial responsibility records where applicable, the driver roster, qualification and medical records, hours of service records, Part 382 drug and alcohol program records for covered drivers, vehicle maintenance files and the accident register.
For a Detroit vehicle transporter, also ask whether the reviewer understands vehicle securement and drive-away/towaway operations. For a carrier that enters Canada or handles through interstate freight, ask whether the reviewer will examine those movements when determining which federal requirements apply.

DOT compliance questions for Detroit
Do on-call drive-away drivers need a Clearinghouse query?
If they are CDL drivers subject to Part 382, yes. Complete the required full pre-employment query before employing them in a covered safety-sensitive position and continue to meet the annual-query requirement while they remain employed.
I run one tow truck and drive it myself. What do I need?
If you are an employer who employs yourself as a CDL driver subject to Part 382, you are treated as an owner-operator for these purposes and must designate a C/TPA in the Clearinghouse.
Can a limited query be used for the annual check?
Yes. A limited query can satisfy the annual requirement when you have the driver's general consent. If it shows that information exists, the required full-query process must follow.
Do we need a provider located in Detroit?
Not for the electronic Clearinghouse query itself. If the provider also manages drug and alcohol testing, confirm that collection-site coverage works for your drivers. === PAGE: mock-dot-audit/michigan/detroit SEO TITLE: Mock DOT Audit in Detroit, MI | DOT Compliance Companies META DESCRIPTION: Mock DOT audit help in Detroit, MI for car haulers, drive-away and towing operations, movers and cross-border carriers.

We only occasionally run to Windsor. Do the federal rules apply?
A Detroit-to-Windsor trip is international commerce. The federal requirements that apply to your carrier, driver and vehicle must therefore be addressed for that operation.
Do drive-away drivers really need full qualification files?
Driver qualification requirements depend on the vehicle and operation. When Part 391 applies to the driver, the required qualification records must be maintained. Part 382 drug and alcohol requirements also apply when the driver is operating a CDL-required CMV and is otherwise within Part 382.
Can a provider come to our Detroit yard?
Some providers offer onsite reviews and others work remotely. Confirm the review method and whether an onsite visit is available for your Detroit location.
How much does a mock DOT audit cost?
Pricing varies with fleet size, number of drivers, locations, record volume and scope. Ask for a written quote that states which compliance areas and how much record history will be reviewed.
