Can an employer wishing to conduct pre-employment alcohol testing, do so?

A DOT-regulated employer (except under USCG rules) wishing to conduct pre-employment alcohol testing under DOT authority may do so if certain conditions are met.
The testing must be accomplished for all applicants (i.e., the employer cannot select for testing some applicants and not others) and the testing must be conducted as a post-offer requirement (i.e., the employer needs to inform the applicant that he or she has the job if he or she passes a DOT alcohol test).
In addition, the testing and its consequences must comply with requirements of Part 40.
