SAP Clearinghouse Program

Having access to a Clearinghouse account can be crucial to completing an SAP Program. The Clearinghouse is a secure database that provides the FMCSA and employers the necessary tools to identify drivers prohibited from operating a commercial moving vehicle based on DOT program violations and ensure that such drivers receive the required evaluation and treatment before operating a CMV on public roads.


The information maintained in the Clearinghouse enables employers to identify drivers who commit a dot program violation while working for one employer but who fail to inform another employer. Records of dot program violations will remain in the Clearinghouse for five years or until the driver has completed the return-to-duty process.

Substance Abuse Professional Program For DOT/FMCSA/FAA/ FRA/PHMSA/USCG

The FMCSA is an entity within the United States Department of Transportation that regulates the trucking industry in America. The primary focuses of the FMCSA are to reduce injuries, crashes, and fatalities involving large trucks and buses.

The FMCSA was created in 2000 due to the Motor Carrier Safety Improvement Act of 1999. The agency consolidated several previous DOT agencies, including the Interstate Commerce Commission’s Office of Motor Carriers (OMC) and parts of the Federal Highway Administration (FHWA).

The FMCSA has authority over all interstate commercial motor vehicle (CMV) carriers, including trucking companies, bus companies, hazardous materials haulers, and passenger carriers. This can also include vehicles with a gross vehicle weight rating (GVWR) or gross combination weight rating (GCWR) greater than 10,000 pounds; vehicles designed to transport 16 or more passengers (including the driver); or any size vehicle carrying hazardous materials requiring placards. In addition to regulating CMV carriers, the FMCSA also sets safety standards for CMV drivers operating in interstate commerce.


Clearinghouse Compliance for Employers

Even though your employer is responsible for providing you with the necessary information on DOT testing protocols, it is ultimately your responsibility as an employee to follow all rules and regulations to keep our roads safe.

Improving the Safety of Commercial Motor Vehicles:

  • Report Dot violations.
  • Report negative return-to-duty (RTD) test results
  • Report successful completion of a follow-up testing plan.
  • Conduct queries to check if prospective employees are prohibited from performing safety-sensitive functions, such as operating CMVs, due to an unresolved dot program violation.
  • Query all current employees at least annually.
  • Electronically view the information in their Clearinghouse record.

Clearinghouse FAQs

What information will the FMCSA DOT Clearinghouse contain?

The Clearinghouse contains DOT violations records, including positive DOT test results and test refusals.

The Clearinghouse also has the steps necessary to complete a return-to-duty (RTD) process and follow-up testing plan.

May drivers access their information in the Clearinghouse?

Yes. Once a driver has registered in the Clearinghouse, they will be able to access their Clearinghouse record electronically. This record would include any DOT program violation information available and the status of their return-to-duty (RTD) process, if applicable.

Who is authorized to use the Clearinghouse?

Authorized users include:

  • CDL drivers
  • Employers
  • Consortia/third-party administrators (C/TPAs)
  • Medical review officers (MROs)
  • Substance abuse professionals (SAPs)
  • Enforcement personnel
How are substance abuse professionals (SAPs) required to use the Clearinghouse?

SAPs use the Clearinghouse to report specific information about a CDL driver’s return-to-duty (RTD) activities. This information includes the completion date of the initial SAP assessment and the date the SAP determines that the driver is eligible for RTD testing.

How is Clearinghouse useful to employers of commercial driver’s license (CDL) and commercial learner’s permit (CLP) holders?

The Clearinghouse offers employers a centralized location to find driver information and report DOT program violations due to their current and prospective employees holding CDLs and CLPs.

Employers can use the Clearinghouse to:

  • Conduct queries for the pre-employment driver investigation process.
  • Conduct queries annually for every driver they employ.
  • Request electronic consent from drivers for query purposes
  • Report DOT program violations.
  • Record return-to-duty (RTD) test results
  • Record date of successful completion of a follow-up testing plan
Can an employer or medical review officer (MRO) enter a DOT program violation in a CDL driver’s Clearinghouse record if the driver is not registered for the Clearinghouse?

Yes. When a violation is entered, the Clearinghouse associates it with a driver’s commercial driver’s license (CDL) information. Even if the driver has not registered for the Clearinghouse, this will be recorded.

When a driver registers with the Clearinghouse, they must enter their CDL information. This allows them to view any violation or return-to-duty (RTD) information associated with their CDL.

May employers report the results of DOT tests not required by the Department of Transportation (DOT) to the Clearinghouse?

No. Only results of DOT DOT tests or refusals may be reported to the Clearinghouse. Employers may conduct DOT testing that is not a part of DOT testing regulation. Still, any positive test results or refusals for non-DOT testing may not be reported to the Clearinghouse.

If a driver has a DOT program violation in one StateState, then applies for a commercial driver’s license (CDL) in another State, will the Clearinghouse be able to connect that driver’s DOT violation history to the new CDL?

Yes. The Clearinghouse can identify drivers who have switched employers or moved to a different state and obtained CDLs in that StateState. This is done to maintain complete and accurate information on such drivers.

What are a medical review officer’s (MRO’s) responsibilities for reporting information to the Clearinghouse?

An MRO must report the following within two business days of deciding or verification of a Department of Transportation (DOT)-approved DOT test:

  • Verified positive, adulterated, or substituted controlled substances test results
  • Refusal-to-test determination.

An MRO must report any changes to a verified DOT test within one business day of changing the reported results.
