Here is the full picture nobody lays out: how all six DOT modes handle Medication-Assisted Treatment.
Three of them have their own medical rulebook that addresses it:
FAA (aviation), FMCSA (trucking/school bus), and USCG (maritime). Three of them rely on the shared Part 40 process instead:
FRA (rail), FTA (transit), and PHMSA (pipeline).
And here is the part worth remembering: not one of the six contains an automatic MAT disqualifier.
So when someone says, "DOT bans MAT," they are wrong twice. Wrong that it is uniform across modes, and wrong that any mode bans it outright.
Save this one. Over the next few posts, I am breaking down each mode, one at a time.
