Common Questions from Employers Considering a Switch
Get answers before you call
How long does it take to switch to US Drug Check from my current C/TPA?
Most employers are fully operational within 48 hours. We handle all transfer paperwork, participant list migration, and random pool setup. You'll speak with your assigned administrator on day one to review your specific needs.
What if I only have 1-5 drivers? Is this worth it for small fleets?
Absolutely. Our owner-operator program is specifically designed for small fleets and independent drivers. You get the same compliance support as large fleets, with pricing that makes sense for your operation size. Many of our clients are owner-operators.
Do you charge extra for Clearinghouse queries and reporting?
Clearinghouse query fees are billed separately. US Drug Check manages the workflow, reporting support, and documentation tracking so required steps are not missed.
What happens if I need a drug test at 2 AM after an accident?
You call our 24/7 emergency line and speak with a live administrator, not a voicemail system. We locate the nearest open collection site and coordinate the test to meet DOT required timeframes for post-accident testing.
How do random selections work? Do I have to manage the process myself?
We manage the entire random selection process. Before each quarterly or monthly pull, we verify your participant roster with you to ensure accuracy. Then we run the selection, generate the analysis reports, and send pre-filled notification letters and collection site instructions.
What if a test result comes back positive? What support do I get?
You're assigned a dedicated program administrator who guides each step: employee communication protocols, required DOT forms, Substance Abuse Professional (SAP) referral, return-to-duty process, and follow-up testing schedules.
