Truck Driver Reference Check: How to Do One

You’ve pulled the records, the paper looks clean, and now you’re staring at a phone number for the applicant’s last carrier. This is the part nobody trains you on: the actual reference call. How do you run a truck driver reference check that tells you something — when half the carriers you call won’t say more than “yes, he worked here”? Here’s what prior employers will and won’t tell you, why they clam up, and how to get a useful answer anyway.

What a truck driver reference check actually is

A truck driver reference check is the phone call (or email, or fax) you make to a commercial driver’s license (CDL) applicant’s previous carriers to ask how they actually performed — attendance, reliability, equipment care, and whether the carrier would take them back. It is the informal, judgment-based half of vetting, and it is not the same thing as the federal safety-history investigation people often confuse it with.

That distinction matters, so be clear on it before you dial. Under 49 CFR §391.23, the Federal Motor Carrier Safety Administration (FMCSA) requires you to investigate a driver’s accident and drug-and-alcohol history with prior Department of Transportation (DOT)-regulated employers — a documented, deadline-bound procedure covered in our guide to DOT employment verification. That’s a safety inquiry with hard scope. A reference check is the broader, voluntary conversation about how the driver was to work with — the stuff §391.23 doesn’t ask about and a prior carrier isn’t required to report. You do both. They’re not interchangeable.

Why reference checks still matter when the paper looks clean

Reference checks matter because the records you’re required to pull only capture events that got written down — and the behaviors that sink most hires never do. A motor vehicle record (MVR) shows citations. A Pre-Employment Screening Program (PSP) report shows crashes and inspections. A DAC report — short for Drive-A-Check, the HireRight-run employment-history file — shows what a former carrier chose to formally enter. None of them reliably show a no-show, a load abandoned without a formal filing, or a driver who left three carriers in eight months.

There’s also a liability angle. Under negligent-hiring doctrine, a carrier that puts an unfit driver in a seat without reasonable vetting can be held responsible when that driver causes harm — and “we never asked” is not a defense. The reference call is part of how you demonstrate you did ask. It’s both an intelligence-gathering step and a risk-management one.

What prior employers will — and won’t — tell you (and why)

Here’s the wall you’ll hit: a large share of carriers, coached by HR or legal, will confirm only dates of employment and job title and nothing about performance. Ask “How was he as a driver?” and you get a polite “We only verify dates.” It’s frustrating, and it’s also based on a misunderstanding.

The fear is a defamation lawsuit. But the legal reality cuts the other way. More than 40 states have job-reference immunity statutes that grant employers a presumption of good faith — meaning a former employer who honestly answers a reference question is shielded from civil liability unless the applicant can show the statement was knowingly false, reckless, or malicious (SHRM). On top of that, most states recognize a common-law qualified privilege for good-faith references, and truth is a complete defense to defamation. The “dates and title only” rule is, as one analysis puts it, “a myth rooted in corporate caution, not legal requirement” (Nolo).

Knowing that won’t change the policy of the carrier you’re calling — but it does tell you two useful things. First, the silence is about their risk tolerance, not your driver. Second, the people most willing to talk are often small-fleet owners and direct supervisors who never got the legal memo. Those are the calls worth chasing.

What to ask: questions that actually get answers

The trick is to ask narrow, factual, often yes/no questions instead of broad performance ones. A cautious HR rep who won’t “give an opinion” will frequently still answer “Would you rehire him?” — because that’s a fact about their decision, not a characterization of the driver. Lead with the questions that survive a guarded conversation.

Two mechanics that raise your hit rate: get the driver’s written consent to contact prior employers before you call (it’s required for the §391.23 piece anyway and it disarms the privacy objection), and document every attempt — carrier, date, method, and what came back, including “would only confirm dates.” That log does double duty as your good-faith-effort record for the federal file.

When references stonewall: filling the gap with peer reviews

Even a perfect call sheet runs into the same wall: the carrier that says “dates only,” the dispatcher who never calls back, the fleet that went out of business last year. You’ve documented the attempt — which satisfies the rule — but you still don’t know whether this driver shows up. That’s the gap, and it’s exactly where the formal stack leaves you blind.

The missing layer is peer reputation — what the carriers who actually employed this driver know but won’t put on the phone. A peer-sourced driver-review database collects that knowledge in writing: previous carriers leave reviews on drivers they’ve employed, so the reliability read survives even when the live reference goes quiet. It doesn’t tell you a citation count (that’s the MVR’s job) or a crash history (that’s PSP) — it tells you the behavioral signal a guarded reference call won’t volunteer. For how to read those reviews like a recruiter instead of a star-rating shopper, see the pillar guide on truck driver reviews.

The CDLScan bridge: reputation when the phone goes silent

On a platform like CDLScan, you can search a driver by name and read what previous carriers said about reliability — whether they showed up, how they handled equipment, and whether the fleet would take them back. It surfaces the no-shows and abandoned-load patterns a dates-only reference will never confirm, before you spend a dollar on orientation.

Be honest about what it is and isn’t. A peer driver-review database complements your reference calls and required checks — it doesn’t replace them. You still pull the MVR, run the PSP, query the Clearinghouse, and complete the §391.23 investigation; those stay mandatory. The reviews add the reputation layer reference calls leave behind. (CDLScan lists more than 1 million driver reviews and runs north of 20,000 searches a week; searching is free, with a full report from $2.75 — against a bad hire that runs $8,000 to $50,000.)

A note on third-party reference services and the FCRA

If you outsource reference calls to a screening vendor, the legal posture changes. When a third party gathers information about an applicant’s character, reputation, or performance through interviews, the result is an investigative consumer report under the Fair Credit Reporting Act (FCRA) — and the FCRA’s employer rules apply. That means you need the applicant’s written authorization up front, and if you decline to hire based on what the report says, you must follow the adverse-action process: send a pre-adverse-action notice with a copy of the report and a summary of FCRA rights, wait a reasonable period (the FTC suggests at least five business days), then send a final notice (FTC).

Calls you make in-house, with your own staff, generally don’t trigger the FCRA the same way — but the moment a vendor is in the loop, treat the output like any other consumer report. The same logic applies to the DAC report and any peer-review report you pay for; for how those obligations work in practice, see our walkthrough on how to get and dispute a DAC report.

Frequently asked questions

What is a truck driver reference check? It’s the practical call you make to a CDL driver’s prior carriers to ask how they performed — attendance, reliability, equipment care, and rehire eligibility. It’s distinct from the federally required §391.23 safety-history investigation, which is a documented inquiry limited to accident and drug-and-alcohol history.

Is a reference check the same as DOT employment verification? No. DOT employment verification under §391.23 is a mandatory, deadline-bound safety investigation into prior DOT-regulated employers. A reference check is the broader, voluntary conversation about reliability and performance. You should do both — they cover different ground.

What can a previous employer legally tell me about a driver? More than they usually will. Over 40 states have job-reference immunity laws protecting good-faith references, and most recognize a qualified privilege. The “dates and title only” practice is corporate caution, not a legal requirement — a former employer can lawfully share truthful performance information.

Why do so many carriers only confirm dates of employment? Fear of a defamation claim, usually on advice from HR or legal. In reality, truthful good-faith references are protected in most states, and the applicant would have to prove the statement was knowingly false or malicious to win.

What questions should I ask in a driver reference check? Narrow, factual ones: Is he eligible for rehire? What were the dates? What equipment did he run? Did he ever leave a load mid-route or miss dispatches? Why did he leave? Yes/no and fact-based questions get answered far more often than open-ended “how was he” questions.

How do I check driver references if the prior carrier won’t respond? Document the attempt — carrier, date, method, outcome — which satisfies your good-faith-effort obligation, then fill the gap with peer reviews from a driver-review database. The records show paper history; the reviews show the reliability signal a silent reference won’t.

Does the FCRA apply to reference checks? It can. If a third-party vendor conducts the reference checks, the result is typically an investigative consumer report, and you must get written consent and follow adverse-action steps before declining based on it. In-house calls by your own staff generally don’t trigger those rules the same way.

Do peer reviews replace the required §391.23 investigation? No. Peer reviews complement reference calls and required checks — MVR, PSP, DAC, and the Clearinghouse stay mandatory, and so does the §391.23 investigation. Reviews add the behavioral reputation layer those checks miss; they don’t substitute for any of them.
