Users who are registered as Clearinghouse Administrators may invite additional users to serve in an Assistant role, enabling them to use the Clearinghouse on their company’s behalf.

Employers that require a USDOT Number manage these Clearinghouse Administrator and Assistant roles via the Federal Motor Carrier Safety Administration (FMCSA) Portal. (Are you a motor carrier without a Portal account? If so, you can register for one now. Make sure all users at your company create their own Portal account with the proper Clearinghouse user role.) Other Clearinghouse Administrators may invite and manage assistants once they are registered in the Clearinghouse.

The Clearinghouse is a secure online database that gives employers, the Federal Motor Carrier Safety Administration (FMCSA), State Driver Licensing Agencies (SDLAs), and State law enforcement personnel real-time information about commercial driver’s license (CDL) and commercial learner’s permit (CLP) holders’ drug and alcohol program violations.

The Clearinghouse contains records of violations of drug and alcohol prohibitions in 49 CFR Part 382, Subpart B, including positive drug or alcohol test results and test refusals. When a driver completes the return-to-duty (RTD) process and follow-up testing plan, this information is also recorded in the Clearinghouse.

Last Updated : January 08, 2020

Whether, and how, a driver staffing agency would register in the Clearinghouse depends on whether the agency functions as an employer, a consortium/third-party administrator (C/TPA), or as both, depending on the services rendered.

The staffing agency should register in the Clearinghouse as an employer if: (1) the staffing agency maintains its own DOT drug and alcohol testing program; and (2) is responsible for ensuring compliance with FMCSA’s drug and alcohol testing requirements for the drivers it employs who are subject to those requirements.

The staffing agency may register in the Clearinghouse as a C/TPA if the motor carrier is responsible for drug and alcohol program compliance, including fulfilling the employer’s querying and reporting requirements, but designates the staffing agency to perform these functions on the carrier’s behalf, as permitted by § 382.711(b).

If the staffing agency will perform both functions, it should create two separate Clearinghouse accounts; one as an employer and one as a C/TPA, using a different email address for each account.

Yes. When a violation is entered, the Clearinghouse associates it with a driver’s commercial driver’s license (CDL) information. This will be recorded even if the driver has not registered for the Clearinghouse. When an employer queries a driver’s information in the Clearinghouse (with the appropriate consent), they will enter the driver’s CDL information to verify if any violations are associated with that driver’s CDL.

A driver is required to enter their CDL information during their Clearinghouse registration. This allows them to view any violation or return-to-duty (RTD) information associated with their CDL.

Last Updated : January 08, 2020

Yes. Once a driver has registered in the Clearinghouse, he or she will be able to access his or her Clearinghouse record electronically, at no cost. This record would include any drug and alcohol program violation information available in the Clearinghouse, along with the status of their return-to-duty (RTD) process, if applicable.

Yes, there is no requirement that the employer personally perform the registration. As part of the Clearinghouse registration process, each authorized user must obtain their own unique login.gov credentials and a user verification process must be completed to ensure that only the authorized user is accessing the Clearinghouse by using those credentials. Regardless of who performs the registration function, the employer is ultimately responsible for compliance with Clearinghouse requirements.

The Clearinghouse is a centralized database that employers use to report drug and alcohol program violations and to conduct queries, which check that current or prospective employees are not prohibited from performing safety-sensitive functions, such as operating a commercial motor vehicle (CMV), due to an unresolved drug and alcohol program violation—that is, a violation for which the driver has not completed the return-to-duty (RTD) process. Queries must be conducted as part of a pre-employment driver investigation, and at least annually for current employees.

In addition, employers may designate a C/TPA who can report violations and/or conduct queries on their behalf. An owner-operator—an employer that employs himself or herself as a CDL driver, typically a single-driver operation—must designate the C/TPA in the Clearinghouse.

To complete the actions outlined above, employers and C/TPAs are required to register in the Clearinghouse.

Yes. The Clearinghouse is subject to certain provisions of the FCRA. However, the Agency does not fall within FCRA’s definition of “consumer reporting agency.” Therefore, provisions of the FCRA that impose obligations on “consumer reporting agencies” do not apply to the Agency’s administration of the Clearinghouse regulations. If an employer or consortium/third-party administrator (C/TPA) is subject to the FCRA, they should comply with their individual requirements.

Employers should consult with their own experts for more information on how to comply with FCRA.

Yes. Employers may designate a C/TPA or C/TPAs to conduct queries and/or report violations on their behalf. The C/TPA must be registered in the Clearinghouse before an employer can select the C/TPA, and C/TPAs must be designated by the employer before reporting drug and alcohol program violations or querying the Clearinghouse on their behalf.

An owner-operator (an employer that employs himself or herself as a commercial driver’s license (CDL) driver, typically a single-driver operation) must designate their C/TPA(s) as part of their Clearinghouse registration process.

It depends on whether the driver is convicted of DUI in a CMV. Current regulations provide that, if an employer has reported an actual knowledge violation based on the issuance of a citation for DUI in a CMV, the driver is prohibited from performing safety-sensitive functions, including driving a CMV, until completing RTD requirements in accordance with 49 CFR part 40, subpart O (subpart O). (See §§ 382.503(a) and 382.605). Employers are prohibited from permitting a driver who has violated subpart B to perform safety-sensitive functions until the driver has complied with the RTD requirements in subpart O. (See §§ 383.503(a) and 382.217(e)).

However, on March 8, 2023, the Federal Motor Carrier Safety Administration (FMCSA) issued a Notice of Enforcement Policy (NEP). The NEP states that FMCSA will not enforce the RTD requirements of §§ 382.503(a), 382.605, and 382.217(e) when drivers violate subpart B, based on their employer’s actual knowledge of the issuance of a citation for DUI in a CMV and the citation results in non-conviction.

The NEP also states that drivers who are convicted of DUI in a CMV must comply with the RTD requirements in accordance with subpart O.

What constitutes “non-conviction” for the purposes of the NEP? As used in the NEP, the term “non-conviction” means that the charge of DUI in a CMV is dismissed without the imposition of fines, court costs, or other punitive actions, or there is an unvacated adjudicated finding of not guilty. Terms that States may use to indicate a dismissal include Nolle Prosequi (Nolle Pros’d or Nolle Prossed), withdrawn, or discontinued. The term “non-conviction” does not include pleading guilty to a lesser charge (e.g., reckless driving).

May a CDL driver who received a traffic citation for DUI in a CMV resume performing safety-sensitive functions before non-conviction is established? No. Drivers who wish to resume safety-sensitive functions before non-conviction has been established (i.e., before the citation has been dismissed or the driver is adjudicated not guilty) must comply with the RTD requirements in subpart O. Prior to non-conviction, an employer may not permit the driver to perform safety-sensitive functions until complying with RTD requirements.

How will FMCSA know that a driver’s citation for DUI in a CMV resulted in non-conviction? To inform FMCSA of the non-conviction, drivers must submit acceptable documentary evidence of non-conviction following the procedures set forth in § 382.717(c).

If the citation for DUI in a CMV results in non-conviction, when may the driver resume safety-sensitive functions? Drivers may resume performing safety-sensitive functions when FMCSA accepts the documentary evidence and changes the driver’s operating status in the Clearinghouse from “Prohibited” to “Not Prohibited.” FMCSA will notify the driver that this information has been added to their record, as required by § 382.707(a), and the driver may then log in to their Clearinghouse account to verify the status change.

Note: If the driver is required to complete the return-to-duty process due to multiple drug and alcohol program violations, including the citation for DUI in a CMV, the driver will be required to complete the return-to-duty process to resolve the other violations before resuming safety-sensitive functions.

If a driver’s citation for DUI in a CMV results in non-conviction and FMCSA accepts documentary evidence of non-conviction and changes the driver’s operating status from “Prohibited” to “Not Prohibited,” must the employer comply with the Clearinghouse reporting requirements in 49 CFR 382.705(b)(1)(ii) and (v)? No. Under the NEP, FMCSA will not enforce the employer reporting requirements for RTD and follow-up testing in §§ 382.705(b)(1)(ii) and (v) when a driver’s citation for DUI in a CMV results in non-conviction and FMCSA changes the driver’s operating status from “Prohibited” to “Not Prohibited” based acceptable documentary evidence of non-conviction submitted by the driver.

Why is FMCSA changing its enforcement policy regarding actual knowledge violations based on the issuance of a citation for DUI in a CMV? The change will increase fairness to drivers while continuing to ensure CMV safety. Issuance of a citation for DUI in a CMV is a serious action, which raises legitimate safety concerns that justify a driver’s immediate removal from safety-sensitive functions. The driver nevertheless should not be required to complete RTD requirements, including directly observed follow-up testing, if the citation results in non-conviction.

Per § 382.705, the following individuals must report the following information:

  • Employers, or consortia/third-party administrators (C/TPAs) acting on behalf of an employer, enter drug and alcohol program violation information into the Clearinghouse.
  • Medical review officers (MROs) enter drug violation information. The driver does not need to be registered in the Clearinghouse for a violation to be added to their Clearinghouse record.
  • Substance abuse professionals (SAPs) enter the date of initial SAP assessment and date the driver is eligible for RTD testing.
  • Employers enter the negative RTD test result(s) and the date the driver’s follow-up testing plan has been successfully completed.

Last Updated : January 08, 2020

Per § 382.705(b), employers must report the following information to the Clearinghouse:

The October 2021 final rule (86 FR 55718) amends 49 CFR part 392 by prohibiting CLP or CDL holders from operating a commercial motor vehicle, as defined in 49 CFR 390.5T, if they are subject to the CMV driving prohibition in 49 CFR 382.501(a). No later than November 18, 2024, States receiving Motor Carrier Safety Assistance Program (MCSAP) grant funds must adopt and enforce a CMV driving prohibition, comparable to 49 CFR 392.15, for CLP and CDL holders who are barred from operating a CMV due to a drug and alcohol program violation.

Last Updated : May 25, 2022

FMCSA is required by statute to include in the Clearinghouse records of violations of 49 CFR, part 382, subpart B. Accordingly, as required by 49 U.S.C. 31306a(g)(6), the actual knowledge violation based on issuance of the citation will remain in the driver’s Clearinghouse record even when the citation results in non-conviction, because the violation of subpart B occurred when the citation was issued. In accordance with the final rule published on October 7, 2021 (86 FR 55718), a report of actual knowledge of prohibited use of drugs or alcohol, based on the issuance of DUI in a CMV, will remain in the Clearinghouse for 5 years, or until the driver has completed the return-to-duty process, whichever is later, regardless of whether the driver is ultimately convicted of the DUI offense. Drivers who are not convicted of the offense may petition to submit documentary evidence of non-conviction to their Clearinghouse record; to learn more about this, view the new frequently asked questions.

On October 7, 2021, the Federal Motor Carrier Safety Administration (FMCSA) published a final rule establishing requirements for SDLA’s access to and use of driver-specific drug and alcohol program violation information contained in the Drug and Alcohol Clearinghouse (86 FR 55718).

This final rule requires that:

  • SDLAs must not issue, renew, upgrade, or transfer a commercial driver's license (CDL), or commercial learner's permit (CLP), as applicable, for any individual prohibited under FMCSA's regulations from performing safety-sensitive functions, including driving a commercial motor vehicle (CMV), due to one or more drug and alcohol program violations.
  • SDLAs must, upon receipt of notification that a driver is prohibited from operating a CMV due to a drug and alcohol program violation, initiate the downgrade process to remove the CLP or CDL privilege from the driver's license within 60 days.
  • Drivers completing the return-to-duty process before the downgrade process is completed would no longer be prohibited from operating a CMV and thus would no longer be subject to a downgrade.

SDLAs have until November 18, 2024 (compliance date) to comply with these requirements. In addition, FMCSA extends the compliance date for the requirement that SDLAs query the Clearinghouse prior to issuing, renewing, upgrading, or transferring a CDL from January 6, 2023 to November 18, 2024. SDLAs currently have the option to voluntarily query the Clearinghouse and may do so before the compliance date.
