CDL and Non-CDL Driver Screening: Key Differences
Screening differences between CDL drivers, non-CDL interstate CMV drivers and drivers outside FMCSA rules, with a decision table.
Short answer
How is screening different for CDL and non-CDL drivers?
CDL drivers are covered by both FMCSA driver qualification rules and the Part 382 drug and alcohol program, so they need MVRs, previous-employer inquiries, a pre-employment drug test and a Clearinghouse full query. Non-CDL drivers of interstate CMVs need the driver qualification steps but not Part 382 testing or Clearinghouse queries. Drivers outside both, such as most car and cargo-van delivery drivers, are screened by employer policy.
Start with the vehicle and the trip
Whether federal rules apply depends on the vehicle's weight rating, passenger count, hazmat placarding and whether the trip is interstate. The definitions in 49 CFR 390.5 control. Intrastate drivers may fall under state rules that mirror federal ones.
Driver screening decision table
| Driver type | Driver qualification file (Part 391) | Pre-employment drug test (Part 382) | Clearinghouse query | Typical policy checks |
|---|---|---|---|---|
| CDL driver, interstate | Required | Required | Required | Criminal, employment history |
| Non-CDL interstate CMV driver | Required | Not under Part 382 | Not applicable | Criminal, non-DOT drug test |
| Intrastate CDL driver | State rules; Part 382 still applies to CDL holders | Required | Required | Criminal |
| Car or cargo-van driver, non-CMV | Not required | Not required | Not applicable | MVR, criminal (policy) |
Frequently asked questions
Can we run a DOT drug test on non-CDL drivers?
No. DOT-form testing is limited to DOT-covered employees. Use a non-DOT test under your own policy and state law.
How often must we review an interstate driver's MVR?
At least once every 12 months under 49 CFR 391.25.
Where can I check which category a driver falls in?
Use the SafestHires DOT background check tool, then confirm with counsel or FMCSA guidance.
