Construction testing is driven from three directions at once: your own CDL drivers fall under FMCSA rules, your company policy covers the trades, and general contractors and project owners increasingly require a testing program as a condition of being on their site. PSI runs all three in one program: the DOT pool for drivers, the policy pool for the crews, pre-employment screening that keeps pace with hiring, and on-site collections at the site trailer, so the crew stays on the job.
What this looks like in practice
- A GC or project owner requires proof of a testing program before mobilization
- CDL drivers within a contractor workforce need a compliant random pool
- Hiring waves at the start of a project need candidate screening that keeps up
- An incident on site calls for a policy-based test, handled discreetly
How PSI runs it
- Documentation that satisfies owner and GC program requirements
- Collections at the site trailer, the yard, or our office, whatever keeps the crew working
- One program covering drivers and trades together
Common questions
A general contractor requires proof of a testing program before we mobilize. Can you provide that?
Yes. We set up the program and provide the documentation general contractors and project owners ask for: the written policy, the pool enrollment, and the screening records.
Do we need DOT testing if only some of our crew holds CDLs?
Your CDL drivers fall under FMCSA rules and need a DOT pool; the rest of the crew is covered by your company policy in a non-DOT pool. We run both, with collections at the site trailer or the yard.
