The U.S. Department of Transportation implemented the Omnibus Transportation Employee Testing Act in December 1992. The Act requires drug and alcohol tests for all safety-sensitive employees of agencies receiving Section 5307, 5309 or 5311 funding (Section 5310 agencies are not included), including drivers and vehicle maintenance workers/mechanics. Grantees receiving FTA funds must have a drug and alcohol testing program in place for all safety sensitive employees and must use drug testing laboratories certified by the Department of Health and Human Services. A notice listing all currently certified laboratories is published in the Federal Register during the first week of each month. Test results and program administration records must be maintained according to federally mandated standards. The grantee is required to refer employees with a verified positive drug test result, a breath alcohol concentration of 0.04, or an employee who has refused to be tested to a Substance Abuse Program (SAP), even if they are to be terminated.
