49 CFR 219.501 - Pre-employment drug testing.
(a) Before an individual performs regulated service the first time for a railroad, the railroad must ensure that the individual undergoes testing for drugs in accordance with the regulations of a DOT agency. No railroad may allow a direct employee (a railroad employee who is not employed by a contractor to the railroad) to perform regulated service, unless that railroad has conducted a DOT pre-employment test for drugs on that individual with a result that did not indicate the misuse of controlled substance. This requirement applies both to a final applicant for direct employment and to a direct employee seeking to transfer for the first time from non-regulated service to duties involving regulated service. A regulated employee must have a negative DOT pre-employment drug test for each railroad for which he or she performs regulated service as the result of a direct employment relationship.
(b) Each railroad must ensure that each employee of a contractor who performs regulated service on the railroad's behalf has a negative DOT pre-employment drug test on file with his or her employer. The railroad must also maintain documentation indicating that it had verified that the contractor employee had a negative DOT pre-employment drug test on file with his or her direct employer. A contractor employee who performs regulated service for more than one railroad does not need to have a DOT pre-employment drug test for each railroad for which he or she provides service.
(c) If a railroad has already conducted a DOT pre-employment test resulting in a negative for a regulated service applicant under the rules and regulations of another DOT agency (such as the Federal Motor Carrier Safety Administration), FRA will accept the result of that negative DOT pre-employment test for purposes of the requirements of this subpart.
(d) As used in subpart H of this part with respect to a test required under this subpart, the term regulated employee includes an applicant for pre-employment testing only. If an applicant declines to be tested and withdraws an application for employment before the pre-employment testing process commences, no record may be maintained of the declination.
(e) The pre-employment drug testing requirements of this section do not apply to covered employees of railroads qualifying for the small railroad exception (see § 219.3(c)) or maintenance-of-way employees who were performing duties for a railroad before June 12, 2017. However, a grandfathered employee must have a negative pre-employment drug test before performing regulated service for a new employing railroad after June 12, 2017.
