{"abstract":"The Department of Transportation is amending certain provisions of its drug and alcohol testing procedures to change instructions to collectors, laboratories, medical review officers, and employers regarding adulterated, substituted, diluted, and invalid urine specimen results. These changes are intended to create consistency with specimen validity requirements established by the U.S. Department of Health and Human Services and to clarify and integrate some measures taken in two of our own Interim Final Rules. This Final Rule makes specimen validity testing mandatory within the regulated transportation industries.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Office of the Secretary"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2008/06/25/E8-14218.html","cfr_references":[{"chapter":null,"citation_url":null,"part":40,"title":49}],"citation":"73 FR 35961","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective August 25, 2008.","disposition_notes":null,"docket_ids":["Docket No. OST-2003-15245"],"dockets":[],"document_number":"E8-14218","effective_on":"2008-08-25","end_page":35975,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2008/06/25/E8-14218.xml","html_url":"https://www.federalregister.gov/documents/2008/06/25/E8-14218/procedures-for-transportation-workplace-drug-and-alcohol-testing-programs","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E8-14218?publication_date=2008-06-25","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2008-06-25/E8-14218/mods.xml","not_received_for_publication":null,"page_length":15,"page_views":{"count":677,"last_updated":"2026-09-21 16:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2008-06-25/pdf/E8-14218.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2008-06-25","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2008/06/25/E8-14218.txt","regulation_id_number_info":{"2105-AD55":null},"regulation_id_numbers":["2105-AD55"],"regulations_dot_gov_info":{"supporting_documents":[],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2105-AD26/procedures-for-transportation-workplace-drug-and-alcohol-testing-programs","title":"Procedures for Transportation Workplace Drug and Alcohol Testing Programs"},"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=DOT-OST-2003-15245","supporting_documents_count":0,"docket_id":"DOT-OST-2003-15245","regulation_id_number":"2105-AD26","title":"Procedures for Transportation Workplace Drug and Alcohol Testing Programs","checked_regulationsdotgov_at":"2011-11-14T09:14:02Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":35961,"subtype":null,"title":"Procedures for Transportation Workplace Drug and Alcohol Testing Programs","toc_doc":"Procedures for Transportation Workplace Drug and Alcohol Testing Programs","toc_subject":null,"topics":["Administrative practice and procedure","Alcohol abuse","Drug abuse","Drug testing","Laboratories","Reporting and recordkeeping requirements","Safety","Transportation"],"type":"Rule","volume":73}
