The short version
- Shift workforces and multi-site employers see the largest gains
- The same Part 40 chain of custody applies in the field, on the Federal form for DOT tests
- Random selections convert to completed collections faster when the collector comes to the site, which is what the rule's proceed-immediately requirement needs (49 CFR 382.305(l))
- Breath alcohol testing can run on site alongside urine collection, inside the window the rule allows for alcohol tests
