It depends. Drivers who perform only FTA-regulated safety-sensitive functions are exempt from Part 382, including the Clearinghouse requirements, as are their employers. These drivers and employers are subject only to the alcohol and/or controlled substances testing requirements of Part 655. On the other hand, FTA-regulated entities that employ drivers who also perform FMCSA-regulated safety-sensitive functions must comply with the relevant alcohol and/or controlled substances testing requirements of Part 382. The following examples illustrate how employers subject to Part 655 also could be subject to Part 382.

Example #1: A driver operates a bus under the authority of the FTA during the week, but sometimes operates a charter bus, for the same employer, on the weekend. The charter operation is regulated by FMCSA, not FTA. If the driver is involved in a crash during the charter operation and is subject to post-accident testing, that testing is conducted under the authority of FMCSA (§ 382.303) and the results must be reported to the Clearinghouse. The same would be true for any testing conducted under the authority of FMCSA (e.g., random testing for drivers in an FMCSA random pool (§ 382.305)). This result is the same for any employer regulated by more than one Department of Transportation (DOT) mode; the modal authority under which the testing is conducted determines which modal regulations apply.

Example #2: A driver regularly operates a bus under the authority of the FTA, but sometimes operates a truck, for which a commercial driver’s license (CDL) is required, for the same employer. In situations like this, the dual FTA/FMCSA regulated employer must conduct a pre-employment query for any driver expected to perform any FMCSA-regulated safety-sensitive functions in the course of their employment, and conduct an annual query for all drivers who have performed any FMCSA-regulated function within the last year.

A limited query allows an employer to determine if an individual driver’s Clearinghouse record has any information about resolved or unresolved drug and alcohol program violations, but does not release any specific violation information contained in the driver’s Clearinghouse record. Limited queries require only a general driver consent, which is obtained outside the Clearinghouse; this general consent is not required on an annual basis, it may be effective for more than one year. However, the limited consent request must specify the timeframe the driver is providing consent for.

A full query allows the employer to see detailed information about any drug and alcohol program violations in a driver’s Clearinghouse record. An employer must obtain the driver’s electronic consent in the Clearinghouse prior to the release of detailed violation information during the full query.

As of March 8, 2023, an employer will be notified via email if a driver they have queried has new information (such as an updated return-to-duty status, a removed violation, or a new violation) recorded in their Clearinghouse record within 12 months of a pre-employment or annual query. The Query History will also be updated to reflect that new information is available. This change is permitted as a “routine use” of the driver’s information under the Privacy Act and is set forth in FMCSA’s System of Records Notice for the Clearinghouse, accessible at 2019-22915.pdf (

Note: Previously, email notifications about new driver information were sent to employers within 30 days of a conducting pre-employment queries only. This has been expanded as described above.

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. Employers who employ CDL holders to operate non-CDL vehicles (i.e., a commercial motor vehicle as defined in 49 CFR 390.5) may, but are not required to, conduct a pre-employment query in accordance with § 382.701(a) or an annual query in accordance with § 382.701(b). Doing so will allow the employer to determine whether the CDL holder had drug and alcohol program violations reported to the Clearinghouse when the driver was operating a commercial motor vehicle, as defined in § 382.107, while subject to the CDL requirements in 49 CFR part 383.

Employers who query the Clearinghouse for CDL holders operating non-CDL vehicles must comply with the applicable employee consent requirements set forth in § 382.703. If a query of the Clearinghouse reveals the CDL holder is prohibited from operating either a CMV or non-CDL CMV under § 382.501(c), the employer must not permit the driver to operate either type of CMV until completing the return-to-duty requirements set forth in 49 CFR part 40, subpart O, as required by § 382.503(a).

Yes. An employer is required to conduct pre-employment and annual queries for all drivers subject to drug and alcohol testing under 49 CFR Part 382.

While the employee may perform more than 50 percent of their functions for a mode other than FMCSA, possibly placing the employee in that agency’s random pool, the Clearinghouse query requirements apply so long as the employee performs any FMCSA-regulated functions.

Employers must conduct an annual query on current employees at least once within a 365-day period based on the date the employer conducted the last query, or another 12-month period determined by the employer, as long as the requirements of 49 CFR 382.701(b) are met.

The annual query requirement is tracked on a rolling 12-month (365-day) basis. For example, if an employer conducts a preemployment query on a prospective employee (or an annual query on a current employee) on December 1, 2022, and the employer is then hired, the employer is not required to conduct another query on that employee again until December 1, 2023.

If an employer receives a notification that a driver has a change to their Clearinghouse record and completes a follow-on query, the follow-on query satisfies the annual query requirement and the rolling 12 months will reset based on the date of the follow-on query. For example, an employer initiated a query on January 1, 2023, then received a notification and requested driver consent for the follow-on query; if the follow-on query is completed on February 1, 2023, the employer would not be required to complete a new annual query on the driver until February 1, 2024.

An employer must conduct a pre-employment query for a prospective employee in the Clearinghouse prior to hiring the employee for a position requiring him or her to perform safety-sensitive functions, such as operating a commercial motor vehicle (CMV). The employer must also query the Clearinghouse annually for all currently employed CDL drivers.

The Clearinghouse offers employers a centralized location to query driver information and report drug and alcohol program violations incurred by their current and prospective employees holding CDLs and CLPs. The employer must use the Clearinghouse to:

  • Conduct a full query of the Clearinghouse as part of each pre-employment driver investigation process.
  • Conduct limited queries at least annually for every driver they employ.
  • Request electronic consent from the driver for a full query, including pre-employment queries.
  • Report drug and alcohol program violations.
  • Record the negative return-to-duty (RTD) test results and the date of successful completion of a follow-up testing plan for any driver they employ with unresolved drug and alcohol program violations.
