If theres a physical involved, you will be asked to change into a gown under Part 40, Section 40.61 of the DOT regulations:

(3) You must not ask the employee to remove other clothing (e.g., shirts, pants, dresses, underwear), to remove all clothing, or to change into a hospital or examination gown (unless the urine collection is being accomplished simultaneously with a DOT agency-authorized medical examination).
