Yes. Under 49 CFR 382.705(b)(1)(ii), employers that are subject to FMCSA’s drug and alcohol regulations in 49 CFR part 382 are required to report drivers’ negative RTD test results to the Clearinghouse. However, if a driver does not have a current or prospective employer subject to part 382 to send the driver for an RTD test and upload the negative result, the driver may register in the Clearinghouse as an owner-operator and designate a consortium/third-party administrator (C/TPA) for the limited purpose of completing the RTD process. Once designated, the C/TPA can direct the driver to submit to an RTD test and report the negative RTD test result to the Clearinghouse on the driver’s behalf. When the C/TPA reports the negative RTD test result, the driver’s Clearinghouse status will change from “prohibited” to “not prohibited,” thereby allowing the driver to resume driving a CMV and performing other safety-sensitive functions. Note: the driver’s follow-up testing plan prescribed by the substance abuse professional must be administered by the driver’s employer when the driver resumes working in a DOT safety-sensitive position.

Drivers using this option will need to create a new account in the Clearinghouse with the “Employer” role (note: this will require creating a new Login.gov account). When registering, select “Register as an Employer and Driver” and be sure to select “Yes” for the question “Are you an owner-operator?” Download step-by-step instructions. Drivers should not apply for a U.S. DOT Number when using this option to complete the RTD process.

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.

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.

Within two business days of making a determination or verification of a Department of Transportation (DOT)-approved drug test, an MRO must report:

The Clearinghouse will notify the driver using the method indicated during the driver’s Clearinghouse registration—either mail or email—any time information about the driver is added, revised, or removed. If the driver has not yet registered for the Clearinghouse, these notifications will be sent by mail using the address associated with the driver’s commercial driver’s license (CDL).

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.

No. As of January 6, 2020, an employer’s valid registration in the Clearinghouse satisfies record retention requirements in §§ 382.701(e) and 391.53(b)(2) since the Clearinghouse now contains three years of drug and alcohol violation data.

The Clearinghouse retains a record of every query an employer conducts. This includes any queries conducted by a designated consortium/third-party administrator (C/TPA) on their behalf. Employers may choose to maintain separate copies of their Clearinghouse queries in a driver qualification file or driver investigation history file or other location but are not required to do so as of January 6, 2023.

However, under § 391.53(b)(2), if the employee was subject to drug and alcohol testing by a Department of Transportation (DOT) mode other than FMCSA, (Federal Railroad Administration, Federal Transit Administration, Federal Aviation Administration, etc.), employers must continue to retain copies of responses received from those DOT-regulated employers in the driver investigation history file, since violation information for other DOT modes is not reported to the Clearinghouse.

Drivers are not required to register for the Clearinghouse. However, a driver will need to be registered to provide electronic consent in the Clearinghouse if a prospective or current employer needs to conduct a full query of the driver’s Clearinghouse record—this includes all pre-employment queries.

A driver must also be registered to electronically view the information in his or her own Clearinghouse record.

Registered drivers will have their Clearinghouse accounts and contact preferences set up, allowing them to quickly respond to query requests from employers. Registration is available at https://clearinghouse.fmcsa.dot.gov/register.

Drivers may:

  • View their own driver record electronically.
  • Provide electronic consent to release detailed drug and alcohol program violation information to a current or prospective employer.
  • Identify a substance abuse professional (SAP) so the SAP may enter specific information regarding the driver’s return-to-duty (RTD) activities.

To complete the actions outlined above, drivers must be registered in the Clearinghouse. Registered drivers will have their Clearinghouse accounts and contact preferences set up, allowing them to quickly respond to query requests from employers. Registration is available at https://clearinghouse.fmcsa.dot.gov/Register .
