Quick answer
Start with a plain-English authority guide, practical tools, and transparent data-product pricing.
DOT drug & alcohol compliance is one of the easiest ways for new carriers to get burned — not because it’s complicated, but because nobody explains it clearly. If you operate CDL commercial motor vehicles, you need to be enrolled in a compliant program.
Who is required to be in a DOT drug & alcohol testing program?
In general, CDL drivers performing safety-sensitive functions must be in a compliant DOT drug & alcohol testing program.
What a compliant program typically includes
- Enrollment with a qualified program/consortium (common for small carriers)
- Random selection/testing process (documented)
- Pre-employment testing (when applicable)
- Post-accident / reasonable suspicion processes (policy + procedures)
- Recordkeeping
How to set it up (simple steps)
- Confirm if your operation requires a DOT drug & alcohol program (CDL = yes in most cases).
- Enroll the company/driver(s) with a compliant consortium/provider.
- Get a written policy and keep it accessible.
- Make sure you’re included in a random testing pool.
- Complete Clearinghouse setup/queries as required.

Random testing (what “random” actually means)
Random means you don’t pick dates or choose who gets tested. Your program/consortium should run documented selections and notify you when testing is required.
FMCSA Clearinghouse
The Clearinghouse is the FMCSA’s system for drug & alcohol violations. Most employers must run required queries and maintain compliance.
Common mistakes new carriers make
- Not enrolling until after authority is granted
- Thinking owner-operators are exempt
- Not being in a random pool
- No written policy / no recordkeeping
FAQ
Do I need this if I’m a one-truck company?
If you operate CDL CMVs, generally yes.
Is this the same as “drug testing for insurance”?
No. Insurance may ask for things, but DOT compliance has specific requirements and enforcement.

ELD for a One-Truck Company
One truck does not skip the ELD. If you keep RODS most days, you need a registered device. True short-haul on timecards may not. Brokers may still ask.
Authority Revoked or Inactive: How to Turn It Back On in Motus
Inactive, lapsed, and revoked are not the same. Motus shows a status plus a reason. Fix insurance, BOC-3, and USDOT first, then request reinstatement. FMCSA lists an $80 reinstatement fee.
How Insurance Gets on File With FMCSA
You buy the policy. The insurer files BMC-91 or BMC-91X. Why Motus can show insurance missing when the policy is fine, and what the official minimums are.
