DOT/FMCSA RIN: 2126-AB18 Publication ID: Fall 2015 
Title: +Commercial Driver's License Drug and Alcohol Clearinghouse (MAP-21) 

This rulemaking would create a central database for verified positive controlled substances and alcohol test results for commercial driver's license (CDL) holders and refusals by such drivers to submit to testing. This rulemaking would require employers of CDL holders and service agents to report positive test results and refusals to test into the Clearinghouse. Prospective employers, acting on an application for a CDL driver position with the applicant's written consent to access the Clearinghouse, would query the Clearinghouse to determine if any specific information about the driver applicant is in the Clearinghouse before allowing the applicant to be hired and to drive CMVs. This rulemaking is intended to increase highway safety by ensuring CDL holders, who have tested positive or have refused to submit to testing, have completed the U.S. DOT's return-to-duty process before driving CMVs in interstate or intrastate commerce. It is also intended to ensure that employers are meeting their drug and alcohol testing responsibilities. Additionally, provisions in this rulemaking would also be responsive to requirements of the Moving Ahead for Progress in the 21st Century (MAP-21) Act. MAP-21 requires creation of the Clearinghouse by 10/1/14.

Statement of Need:

This rulemaking would improve the safety of the Nation's highways by ensuring that employers know when drivers test positive for drugs and/or alcohol and are not qualified to perform safety-sensitive functions. It would also ensure that drivers who have tested positive and have not completed the return to duty process are not driving and will ensure that they receive the required evaluation and treatment before resuming safety-sensitive functions.

Summary of the Legal Basis:

Section 32402 of the Moving Ahead for Progress in the 21st Century Act (MAP-21)) (Pub. L. 112-141, 126 stat. 405) directs the Secretary of Transportation to establish a national clearinghouse for controlled substance and alcohol test results of commercial motor vehicle operators. In addition, FMCSA has general authority to promulgate safety standards, including those governing drivers' use of drugs or alcohol while operating a CMV. The Motor Carrier Safety Act of 1984 Public Law 98-554 (the 1984 Act) provides authority to regulate drivers, motor carriers, and vehicle equipment and requires the Secretary of Transportation to prescribe minimum safety standards for CMVs. Including: (1) CMVs are maintained, equipped loaded, and operated safely; (2) the responsibilities imposed on CMV operators do not impair their ability to operate the vehicles safely; (3) the physical condition of CMV operators is adequate to enable them to operate the vehicles safely; and (4) CMV operation does not have a deleterious effect on physical condition of the operators; and (5) CMV drivers are not coerced by a motor carrier, shipper, receiver, or transportation intermediary to operate a CMV in violation of regulations promulgated under(49 U.S.C. 31136(a)).


To be determined.

Anticipated Costs and Benefits:

In the final rule the Agency estimated $230 million in annual benefits from increased crash reduction from the rule. This is against an estimated $174 million in total annual costs.


A risk of not knowing when a driver has not completed the "return to duty" process and enabling job-hopping within the industry.
