PHMSA mandates [urine](https://amhnationwide.com/urine-drug-testing/) drug screening using the federally certified protocol under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). This protocol requires collection at approved sites with chain-of-custody procedures and analysis by certified national labs. Hair or other specimen types do not meet PHMSA testing requirements. EMPLOYER DECISIONS ## When should employers choose PHMSA drug testing versus other tests? Employers must select PHMSA drug testing which test matches the regulatory mandate for safety-sensitive positions. For PHMSA-regulated roles, urine testing under the 49 CFR Part 40 protocol is required for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/), random, reasonable suspicion, post-accident, [return-to-duty](https://amhnationwide.com/dot-return-to-duty/), and follow-up testing. Alternative tests such as hair or saliva may be used for non-regulated positions or additional screening but do not satisfy PHMSA requirements. PHMSA drug testing: federally certified urine test, mandatory for safety-sensitive roles Hair testing: suitable for non-DOT roles or extended detection windows Saliva testing: rapid screening but not PHMSA compliant LEGAL CONTEXT ## Which test is appropriate for court or probation drug testing compared to PHMSA testing?

Courts and probation departments often accept a variety of tests including urine, hair, or saliva depending on their policies. Urine testing under 49 CFR Part 40 may be used if the case involves transportation safety regulations. Otherwise, hair or saliva tests may be chosen for longer detection windows or convenience.
