Scientifically valid selection
Draws made by an approved random method from your current roster, with the method and date documented for every cycle.
Random testing that is genuinely random — and provably so.
Selections drawn by a scientifically valid method, spread reasonably across the year, monitored against the current federal rate, and documented so an investigator can verify every draw.
Why random testing is the number one audit finding
Random testing looks simple and almost never is. Auditors do not just ask whether you tested — they ask whether the selection was scientifically valid, whether every eligible employee was in the pool on the day of the draw, whether tests were spread reasonably through the year, and whether you hit the required annual percentage. Fail any of those and it does not matter that the tests came back negative.
The most common ways carriers fall short:
- Drivers hired mid-year never added to the pool, so the roster is stale by the third quarter.
- All the year's selections crammed into Q4 once someone realises the rate is short.
- A selected driver quietly skipped because they were on the road, with no documented follow-up.
- Pool counts that no longer match the driver list in the DQ files.
Consortium pool or dedicated pool?
Both are fully compliant. The right one depends on your size.
| IPS consortium pool | Dedicated company pool | |
|---|---|---|
| Best for | Owner-operators and fleets under roughly 50 drivers | Fleets with enough drivers to smooth the selection maths |
| How it works | Your drivers join a large multi-employer pool | Selections drawn from your drivers only |
| Predictability | Cost and volume smoothed across the group | Testing volume tracks your own headcount |
| Compliance certificate | Issued for brokers, shippers and insurers | Issued on request |
A one-truck owner-operator cannot meaningfully self-test at a 50% annual rate — you cannot test half a driver. That is exactly what a consortium is for, and why the FMCSA permits it.
Know your rate — it can change
Each DOT agency publishes a minimum annual random testing percentage, and those percentages are reviewed and can be adjusted. FMCSA has held its controlled-substances rate at 50% of the average number of driver positions and alcohol at 10% in recent years; FAA, FTA, PHMSA and USCG each set their own. We track the published rates and adjust your pool draws automatically — you are never the last to find out a rate moved.
Rate monitoring is included. Your portal shows tests completed versus tests required, so you can see in one glance whether you are on pace — not discover it in December.
What a defensible selection record looks like
For every draw we retain the pool roster as it stood that day, the selection method, the date and time of the draw, the drivers selected, the notification, and the completed test — or the documented reason a test could not be completed and what happened next. That package is what turns "we do random testing" into something an auditor can verify in ten minutes.
When a selected driver cannot test
It happens — the driver is 900 miles away, on vacation, or out on medical leave. What matters is that the reason is documented at the time and that the test is completed when the driver returns, or the selection is properly handled under your programme. Undocumented misses are what auditors find. We chase the completion and log the trail for you.
What's included
Pool management, start to finish
Enrolment, selection, notification, chasing and reporting — the whole loop, not just the draw.
Live roster management
New hires added and departures removed as they happen, so the pool always matches your actual driver list.
Reasonable spread
Selections distributed across the year rather than bunched, which is exactly what auditors check for.
Rate tracking
Completed versus required tests visible in your portal all year, against the current published federal minimum.
Notification & chasing
Your DER is alerted the moment a selection is ready, and we follow up until every selected test is closed out.
Compliance certificate
Proof of consortium membership for brokers, shippers, insurers and new-entrant audits.
How it works
One enrolment. A year of compliance.
Random management is a cycle, not an event. We run every turn of it and keep the evidence.

FAQ
Random Consortium — your questions
A consortium (formally a C/TPA-managed pool) combines drivers from multiple employers into a single random selection pool. It allows small fleets and owner-operators to meet the federal random testing percentage, which is mathematically impossible to satisfy with one or two drivers on their own. Membership is expressly permitted by DOT rules.
FMCSA has maintained a minimum annual rate of 50% of average driver positions for controlled substances and 10% for alcohol in recent years, but the agency reviews and can adjust these rates. Other DOT agencies set their own. IPS tracks the published rate for your agency and adjusts your selections automatically.
No. An owner-operator with no other employees cannot form a valid random pool alone and must join a consortium to be compliant. This is one of the most frequently cited findings against small carriers.
Send them to the nearest collection site — with 1500+ sites nationwide, that is usually a short detour rather than a trip home. If the test genuinely cannot be completed within the cycle, the reason must be documented at the time and the test completed when the driver returns. We chase and document this for you.
Most programs are live within 24 hours. We request your records from the outgoing administrator, reconcile the roster, load your drivers into the pool and issue a compliance certificate. There is no setup fee and no gap in coverage.
Yes. DOT rules require selections to be reasonably spread throughout the calendar year. Running all of your tests in the final quarter to catch up on the rate is itself a finding, even if you end the year at the correct percentage.
