It should also be understood that a Federally Regulated CCF need not be used in every situation involving a company regulated by the Department of Transportation. For example, if an interstate truck driver slips and falls while standing on the loading dock of a trucking terminal, and the trucking company for which the driver works requires a post-accident drug screen, a Non-Federally Regulated CCF would be appropriate for this collection. The driver was not involved in a safety sensitive assignment. On the other hand, if the driver had an accident while driving, then a Federally Regulated CCF must be used since the driver was in a safety sensitive position when the accident occurred.
