At the discretion of a licensee or other entity in [§ 26.3(c)](/cfr/10/26.3.md?p=c), specimen collections and alcohol tests must be conducted either under this subpart for the individuals specified in § [26.4(e)](/cfr/10/26.4.md?p=e) and [(f)](/cfr/10/26.4.md?p=f) or the licensee or other entity may rely on specimen collections and alcohol tests conducted under the requirements of [49 CFR part 40](/cfr/49/part40.md) for the individuals specified in § [26.4(e)](/cfr/10/26.4.md?p=e) and [(f)](/cfr/10/26.4.md?p=f).
