So-called “Chain of Custody” (CoC) forms are essential .We all know that they’re a required part of the DOT drug and alcohol testing process. But did you also know that a record of these forms MUST be kept by motor carriers? It’s not uncommon for auditors to ask for them during an audit – yet many carriers don’t hold on to them for very long after a test is complete.
These forms also enable Medical Review Officers to report positive drug and alcohol violations to the DOT Clearinghouse – a requirement that started in 2020. To make this possible, the Custody and Control form was updated last year to include the driver’s commercial driver’s license (CDL) number. This is now used instead of the driver’s EIN or SSN for identification purposes.
