DOT Rule 49 CFR Part 40 Section 40.221
Subpart K - Testing Sites, Forms, Equipment and Supplies Used in Alcohol Testing
§ 40.221 Where does an alcohol test take place?
(a) A DOT alcohol test must take place at an alcohol testing site meeting the requirements of this section.
(b) If you are operating an alcohol testing site, you must ensure that it meets the security requirements of §40.223
(c) If you are operating an alcohol testing site, you must ensure that it provides visual and aural privacy to the employee being tested, sufficient to prevent unauthorized persons from seeing or hearing test results.
(d) If you are operating an alcohol testing site, you must ensure that it has all needed personnel, materials, equipment, and facilities to provide for the collection and analysis of breath and/or saliva samples, and a suitable clean surface for writing.
(e) If an alcohol testing site fully meeting all the visual and aural privacy requirements of paragraph (c) is not readily available, this part allows a reasonable suspicion or post-accident test to be conducted at a site that partially meets these requirements. In this case, the site must afford visual and aural privacy to the employee to the greatest extent practicable.
(f) An alcohol testing site can be in a medical facility, a mobile facility (e.g., a van), a dedicated collection facility, or any other location meeting the requirements of this section.
