MVR vs. PSP vs. DAC vs. Clearinghouse: What CDL Drivers Need to Know
Understand the four records used in CDL hiring, what each one contains, who can access it, and where a correction actually begins.
Information note: This guide was reviewed for accuracy on August 4, 2026. Government procedures, state record systems, fees, and regulations can change. Always confirm current instructions with the agency or company responsible for the record. This article provides general educational information and is not legal advice. America First Logistics cannot access, alter, or correct a driver's private records, and individual carriers make their own hiring decisions.
Quick Answer
An MVR, PSP report, DAC report, and Drug and Alcohol Clearinghouse record are four different sources of driver information.
A clean result in one does not mean the others are clear. Each is maintained by a different organization, contains different information, and has its own access and correction process.
The first step is identifying which record actually contains the information you are concerned about.
Why There Is No Single “Complete Driver Record”
Drivers often hear that a carrier is going to "check their record." That phrase can be misleading because there is no single report containing every piece of information a trucking company might review.
A carrier may obtain or review several separate sources during hiring, including:
- State licensing and driving-history information
- FMCSA crash and roadside-inspection data
- Information supplied by previous employers
- Required Drug and Alcohol Clearinghouse information
- Other employment background reports permitted by law
These sources do not automatically contain identical information. The same event may appear differently in more than one system—or may appear in only one.
For example:
- A roadside inspection may appear on a PSP report without appearing as a conviction on the driver's MVR.
- A former employer may report an accident or rehire status through DAC even though that information is not part of the driver's PSP report.
- A prohibited Clearinghouse status can affect commercial driving privileges, but the Clearinghouse itself is not an ordinary state driving record.
A clean MVR does not prove that a driver has no PSP, DAC, or Clearinghouse information.
Four Sources, Four Different Purposes
| Source | Maintained or provided by | Type of source | Main question it answers | Common information | It is not a complete source for |
|---|---|---|---|---|---|
| MVR | State driver-licensing agency | State government record | What is the driver's current license status and state-recorded driving history? | License class, endorsements, restrictions, convictions, points, suspensions, revocations and disqualifications; other entries vary by state | FMCSA inspection history, complete employment history or DAC information |
| PSP | Federal Motor Carrier Safety Administration | Federal safety-data program | What FMCSA-reportable crashes and roadside inspections are associated with the driver? | Five years of crash data and three years of roadside-inspection data | Complete license history, general employment history, DAC information or Clearinghouse status |
| DAC | HireRight | Private consumer report | What employment information have participating employers furnished? | Employment dates, equipment, work history, accidents, reason for leaving or rehire eligibility, depending on what was reported | Universal employment history, official license status or complete FMCSA safety history |
| Clearinghouse | Federal Motor Carrier Safety Administration | Secure federal database | Does the driver have covered DOT drug or alcohol violation and return-to-duty information? | Covered violations, prohibited status and return-to-duty information | Tickets, inspections, general crash history, criminal history, non-DOT tests or complete employment history |

Motor Vehicle Record
What an MVR is
A Motor Vehicle Record is the driving record maintained by a state driver-licensing agency.
Depending on the state and the type of record ordered, an MVR may show:
- Current license status
- License class
- CDL endorsements
- Restrictions
- Traffic convictions
- Points
- Suspensions
- Revocations
- Cancellations
- Commercial disqualifications
- Crashes or administrative actions
- Medical-certification status
- A CDL downgrade
The exact contents and lookback period vary by state. Some states offer several products, such as a status-only record, a three-year history, a seven-year history, or a complete driving record.
That means drivers should not assume the cheapest or shortest record contains everything they need. Read the description of each record product before ordering.
Why carriers review it
Federal regulations require motor carriers to obtain driving-history information from the applicable state licensing authorities during driver qualification. Carriers must also review an employed driver's MVR at least annually. The state determines how the record is supplied. 49 CFR §391.23, 49 CFR §391.25
What an MVR does not tell you
An MVR is not a complete federal safety report or employment-history report. It ordinarily does not provide:
- Every FMCSA roadside inspection
- Complete PSP crash information
- A driver's complete work history
- DAC information
- Complete Clearinghouse violation details
Where an MVR correction begins
The correct starting point depends on what is wrong.
- The court disposition is wrong or incomplete: Begin with the court that handled the case.
- The court has the correct disposition, but the state record is wrong: Contact the state driver-licensing agency.
- The state requires proof: You may need to obtain a certified court disposition or other official documentation.
DataQs is not the normal correction system for an ordinary state MVR entry.
For complete instructions, see How to Get and Review Your Motor Vehicle Record in the America First Logistics Driver Resource Center.
PSP Report
What PSP contains
The FMCSA Pre-Employment Screening Program provides safety information associated with a commercial driver, including:
- Five years of FMCSA-reportable crash data
- Three years of roadside-inspection data
- Inspections with violations
- Inspections without violations
- Carrier and inspection information associated with those events
- Certain inspection-violation adjudication information
- FMCSA crash-preventability determinations when an eligible crash has been reviewed
A driver can request their PSP report through the official FMCSA PSP website.
An inspection violation is not automatically a conviction
PSP information is primarily based on roadside inspections and reportable crashes. It is not simply another version of your state traffic-conviction history.
An officer may document an inspection violation even when:
- No citation was issued
- A citation was later dismissed
- The driver was not convicted
- The violation concerned the vehicle or carrier rather than conduct normally shown as a state traffic conviction
Some adjudication information associated with inspection-related citations may be added to FMCSA data. That does not make the PSP report the same as an MVR.
A crash does not establish fault
A crash appearing on a PSP report does not, by itself, mean FMCSA determined that the driver caused it.
The official PSP disclosure explains that crash information does not assign or imply fault. Reportable crashes may appear regardless of fault. FMCSA PSP Disclosure and Authorization Form
If an eligible crash has been reviewed through FMCSA's Crash Preventability Determination Program, the result may be displayed. However, the absence of a "Not Preventable" determination does not prove that a crash was preventable.
PSP also does not give an individual driver a safety score.
How carriers access PSP
PSP is a pre-employment screening program. An enrolled prospective employer must obtain the driver's required written or electronic authorization before requesting the report.
Not every carrier uses PSP, and federal regulations do not require every carrier to purchase a PSP report on every applicant.
Where a PSP correction begins
If FMCSA crash or roadside-inspection data is incomplete or incorrect, the correction process generally begins through DataQs.
DataQs does not decide ordinary state traffic cases and cannot erase accurate information merely because it is unfavorable. Supporting documents are important.

DAC Report
What DAC is
DAC is a private employment-history consumer-reporting product provided by HireRight. It is not an FMCSA database, an MVR, or a universal employment record.
Participating employers may furnish information such as:
- Employment dates
- Equipment operated
- Types of loads hauled
- Driver status or experience
- Reason for leaving
- Rehire eligibility
- Accident information
- Truck-driving-school performance
The actual contents depend on what participating employers reported. Some employers do not use DAC, some do not report every field, and some drivers may not have an active DAC file.
DAC is not required for every carrier
Federal regulations require carriers to investigate certain prior-employer safety-performance information. However, the regulations allow multiple investigative methods and do not require carriers to use HireRight or DAC. 49 CFR §391.23
A carrier may contact previous employers directly, use a reporting company, or use other permitted methods.
How to obtain your DAC information
Drivers may request a free consumer disclosure from HireRight containing their DAC Employment History File or other active file information, if a file exists.
Use HireRight's official instructions for requesting a copy of your DAC report. You do not need to purchase an unofficial third-party service just to exercise your disclosure rights.
Your consumer-reporting rights
DAC reports are consumer reports subject to the Fair Credit Reporting Act.
Depending on the application method and circumstances, the exact disclosure and permission process may differ. The law includes a transportation-specific procedure for certain remote applications to DOT-regulated driving positions, so not every driver will necessarily see the same form.
If information from a consumer report affects an employment decision, read every notice you receive. It may identify:
- The consumer-reporting company involved
- How to request a copy of the report
- How to dispute inaccurate or incomplete information
- Other rights that may apply before or after an adverse employment decision
Where a DAC correction begins
If DAC information is inaccurate or incomplete, submit a formal dispute to HireRight. The dispute process is free.
HireRight may contact the former employer or other source that furnished the disputed information. The former employer may therefore be involved, but drivers should not rely only on an informal call to the former employer when a formal consumer-report dispute is available.
Use HireRight's official background-report dispute instructions.
For more help, see How to Get Your DAC Report in the Driver Resource Center.
FMCSA Drug and Alcohol Clearinghouse
What the Clearinghouse is
The Drug and Alcohol Clearinghouse is a secure federal database containing specified violations of FMCSA's DOT drug-and-alcohol testing program for CDL and CLP holders.
It may contain:
- Verified positive DOT drug-test results
- Verified adulterated or substituted results
- DOT test refusals
- Alcohol confirmation results of 0.04 or higher
- Certain employer reports based on actual knowledge
- Substance Abuse Professional assessment information
- Return-to-duty eligibility information
- Negative return-to-duty test information
- Completion of required follow-up testing
Different parties report different events, including employers, Medical Review Officers, Substance Abuse Professionals, and designated consortium/third-party administrators.
What the Clearinghouse does not normally contain
The Clearinghouse is not a general background report. It does not normally contain:
- Traffic tickets
- Roadside inspections
- General crash history
- Criminal history
- Complete employment history
- Non-DOT drug tests
- Every negative DOT drug or alcohol test
It is more accurate to describe the Clearinghouse as a database of specified violations and return-to-duty information—not a record of every drug or alcohol test a driver has ever taken.
Viewing your own record
Drivers may register and view their own Clearinghouse information electronically.
Registration is not universally required merely because a record could exist. However, a driver must register to:
- View their own record online
- Respond to an employer's full-query consent request
- Select a Substance Abuse Professional when required
FMCSA explains these driver functions in its Clearinghouse query and consent guidance.
Limited and full queries
A limited query tells an employer whether the Clearinghouse contains resolved or unresolved violation information. It does not release the details.
- It requires general written or electronic consent obtained outside the Clearinghouse.
- The consent may cover more than one year if the duration is stated.
A full query allows an employer to view detailed information.
- It requires the driver's specific electronic consent inside the Clearinghouse.
- Every pre-employment Clearinghouse query is a full query.
If a limited query indicates that information exists, the employer must follow the required process for a full query.
Employers must conduct a pre-employment full query and at least an annual query for covered drivers. FMCSA Clearinghouse guidance
Prohibited status and CDL consequences
A driver with a prohibited Clearinghouse status cannot perform a safety-sensitive function, including operating a commercial motor vehicle.
Completing the return-to-duty requirements can make the driver eligible for reinstatement. It does not necessarily mean the physical CDL or commercial privilege is restored instantly without any state processing.
Drivers should verify both:
- Their Clearinghouse status
- Their current state license status
Correcting Clearinghouse information
Clearinghouse corrections are more complicated than simply contacting whoever reported the entry. The correct federal route depends on what the driver is challenging.
A petition under 49 CFR §382.717 may apply to certain administrative or reporting errors, such as duplicate information, inaccurate transcription of supporting documents, or specified documentation problems.
However, that petition generally cannot be used simply to challenge the validity of a drug-test result, refusal or other violation. Those disputes may require FMCSA's current Privacy Act correction process.
Drivers should follow the current instructions carefully and provide documents explaining exactly what is wrong. Accurate information is not removed merely because it creates employment or licensing consequences. See 49 CFR Part 382 and FMCSA's Clearinghouse correction guidance.
How Access and Corrections Differ

Which Record Should You Check?
Use the type of information you are concerned about to identify the correct source.
Check your MVR
- License status
- CDL class
- Endorsements or restrictions
- Traffic convictions
- Points
- Suspensions
- Disqualifications
- Ticket disposition
- Medical-certification status or a state CDL downgrade
Check your PSP
- A roadside inspection
- An inspection violation
- An out-of-service event
- An FMCSA-reportable commercial-vehicle crash
- A crash-preventability determination
- Incorrect FMCSA crash or inspection data
Check your DAC report
- Employment dates
- Equipment or work experience
- Reason for leaving
- Rehire eligibility
- Accident information furnished by an employer
- Other prior-employer information reported through HireRight
Check the Clearinghouse
- A DOT drug or alcohol violation
- A reported refusal
- Prohibited status
- Substance Abuse Professional information
- Return-to-duty eligibility
- Completion of follow-up testing
Check more than one source when:
- The event could affect both federal and state records
- A Clearinghouse status may have affected your CDL
- A crash or citation appears in more than one system
- You do not know which report influenced a hiring decision
If you receive a background-check or adverse-action notice, read it carefully. It should help identify the consumer-reporting company involved.
Where Corrections Begin
| What appears to be wrong | Where to begin |
|---|---|
| Court disposition | Court that handled the case |
| State license or MVR entry | State driver-licensing agency |
| FMCSA crash or inspection information | DataQs |
| DAC or another employment consumer report | Consumer-reporting company and, when appropriate, the employer or other furnisher |
| Clearinghouse administrative or reporting error | Current §382.717 petition instructions |
| Clearinghouse test, refusal or violation challenge outside §382.717 | Current Privacy Act correction instructions |
- Court disposition
- Court that handled the case
- State license or MVR entry
- State driver-licensing agency
- FMCSA crash or inspection information
- DataQs
- DAC or another employment consumer report
- Consumer-reporting company and, when appropriate, the employer or other furnisher
- Clearinghouse administrative or reporting error
- Current §382.717 petition instructions
- Clearinghouse test, refusal or violation challenge outside §382.717
- Current Privacy Act correction instructions
One event may require more than one correction
Correcting the original source does not guarantee that every other report will update immediately.
For example, a corrected court disposition may still need to be processed by the state. A corrected federal record may need to be confirmed on a newly requested report. An erroneous Clearinghouse prohibited status may have caused a state licensing action that also needs verification.
After a correction:
- Keep copies of the supporting documents.
- Obtain written confirmation when possible.
- Allow the stated processing time.
- Request a fresh copy of each affected record.
- Confirm that the correction appears everywhere it should.
Review Your Information Before Applying
When possible, complete these steps before sending applications:
Before you apply
- Verify that your CDL is active.
- Confirm your class, endorsements and restrictions.
- Make sure your medical-certification status is current.
- Review the appropriate MVR product from your state.
- Review your PSP report if you have commercial driving history.
- Request your DAC disclosure if you believe participating employers may have reported information.
- Register for and review your Clearinghouse record.
- Compare the reports with your own documents and dates.
- Begin disputes or corrections before applying when practical.
- Read any background-check or adverse-action notice carefully.
You do not need to order every possible report before every application. The goal is to understand which sources are relevant to your history and to avoid being surprised by information you could have reviewed yourself.

Frequently Asked Questions
No. An MVR is maintained by a state driver-licensing agency and focuses on license status and state-recorded driving history. PSP is an FMCSA program containing specified commercial crash and roadside-inspection data.
No. These are separate sources. A clean result in one does not establish what appears in the others.
No. A crash's appearance does not assign or imply fault. A separate FMCSA preventability determination may appear if an eligible crash was reviewed.
No. DAC is a private HireRight product, and its coverage depends on participating employers. Federal regulations do not require every carrier to use DAC.
Not ordinarily. DataQs is used for eligible FMCSA data concerns, especially crash and roadside-inspection information. Courts, state licensing agencies, consumer-reporting companies and the Clearinghouse have separate processes.
Yes. A registered driver can view their own Clearinghouse record electronically without paying for an employer query.
Do not assume it will. The same event may exist in several systems. Obtain fresh copies and verify every affected record after the correction is processed.
America First Logistics can direct you to the appropriate official resources and help you understand general carrier requirements. It cannot access your private accounts, correct official records or act as a consumer-reporting company.
Check the source connected to your concern:
- License or conviction issue: MVR
- Crash or roadside inspection: PSP
- Prior-employer reporting: DAC
- DOT drug or alcohol violation or return-to-duty status: Clearinghouse
If you have concerns in more than one category, review more than one source.
