(a) Each railroad must require a regulated employee to submit to a breath alcohol test when the railroad has reasonable suspicion to believe that the regulated employee has violated any prohibition of subpart B of this part concerning use of alcohol. The railroad's determination that reasonable suspicion exists to require the regulated employee to undergo an alcohol test must be based on specific, contemporaneous, articulable observations concerning the appearance, behavior, speech, or body odors of the employee. A Federal reasonable suspicion alcohol test is not required to confirm the on-duty possession of alcohol.

(b) Each railroad must require a regulated employee to submit to a drug test when the railroad has reasonable suspicion to believe that the regulated employee has violated the prohibitions of subpart B of this part concerning use of controlled substances. The railroad's determination that reasonable suspicion exists to require the regulated employee to undergo a drug test must be based on specific, contemporaneous, articulable observations concerning the appearance, behavior, speech, or body odors of the employee. Such observations may include indications of the chronic and withdrawal effects of drugs.

(c) Reasonable suspicion observations made under this section must comply with the requirements of § 219.303.

(d) As provided by § 219.11(b)(2), in any case where an employee is suffering a substantiated medical emergency and is subject to alcohol or drug testing under this subpart, necessary medical treatment must be accorded priority over provision of the breath or body fluid specimens. However, when the employee's condition is stabilized, reasonable suspicion testing must be completed if within the eight-hour limit provided for in § 219.305.

(a) With respect to an alcohol test, the required observations must be made by a responsible railroad supervisor (defined by § 219.5) trained in accordance with § 219.11(g). The supervisor who makes the determination that reasonable suspicion exists may not conduct the reasonable suspicion testing on that regulated employee.

(b) With respect to a drug test, the required observations must be made by two responsible railroad supervisors (defined by § 219.5), at least one of whom must be both on site and trained in accordance with § 219.11(g). If one of the supervisors is off site, the on-site supervisor must communicate with the off-site supervisor, as necessary, to provide him or her the information needed to make the required observation. This communication may be performed via telephone, but not via radio or any other form of electronic communication.

(c) This subpart does not authorize holding any employee out of service pending receipt of toxicological analysis for reasonable suspicion testing, nor does it restrict a railroad from taking such action based on the employee's underlying conduct, provided it is consistent with the railroad's policy and taken under the railroad's own authority.

(d) The railroad must maintain written documentation that specifically describes the observed signs and symptoms upon which the determination that reasonable suspicion exists is based. This documentation must be completed promptly by the trained supervisor.

(a) Consistent with the need to protect life and property, testing under this subpart must be conducted promptly following the observations upon which the testing decision is based.

(b) If a test required by this subpart is not administered within two hours following a determination made under this section, the railroad must prepare and maintain on file a record stating the reasons the test was not administered within that time period. If an alcohol or drug test required by this subpart is not administered within eight hours of a determination made under this subpart, the railroad must cease attempts to administer the test and must record the reasons for not administering the test. The eight-hour requirement is satisfied if the individual has been delivered to the collection site (where the collector is present) and the request has been made to commence collection of the specimens within that period. The records required by this section must be submitted to FRA upon request of the FRA Drug and Alcohol Program Manager.

(c) A regulated employee may not be tested under this subpart if that individual has been released from duty under the normal procedures of a railroad. An individual who has been transported to receive medical care is not released from duty for purposes of this section. Nothing in this section prohibits the subsequent testing of an employee who has failed to remain available for testing as required (i.e., who is absent without leave).
