I forgot to mention that I believe the level should be the same across the board for CDL's, pilots, and the general public. Why should a CDL or pilot be held to a higher standard when off work?
For people actually performing their jobs, it should be zero! No CDL or pilot should ever test positive for alcohol or any substance while on the job. I know that if I would test positive for alcohol, or any substance while on the job, I would not have to worry about showing up on time anymore. I would be placed on leave, license suspended with mandatory counseling. Pending completion, I may get my license reactivated.
