English Proficiency and the Clearinghouse: The Driver Violations Now Pulling Trucks Off the Road

A lot of carrier-safety conversation fixates on the truck — brakes, tires, maintenance. But a truck is only as safe as the person driving it, and two driver-qualification rules have just gotten serious enforcement teeth in a way that's reshaping roadside inspections and CDL eligibility right now. Both are exactly the kind of thing that turns up in the FMCSA data you screen *before* a load moves, and both are worth understanding in plain terms.

The two: **English Language Proficiency (ELP)**, which is an out-of-service violation again, and the **Drug & Alcohol Clearinghouse**, which now forces states to strip the CDLs of drivers in prohibited status. Let's take each one, then connect them to what a careful broker or shipper actually does with the information.

English Language Proficiency is an out-of-service violation again

The requirement itself isn't new. Federal regulation **49 CFR § 391.11(b)(2)** has long required that a commercial driver be able to "read and speak the English language sufficiently" to converse with the public, understand highway traffic signs and signals, respond to official inquiries, and make entries on reports and records. What changed is *enforcement.*

In 2016, FMCSA had issued guidance that effectively stopped inspectors from placing drivers out of service for ELP violations. That changed in 2025:

• Executive Order 14286, "Enforcing Commonsense Rules of the Road for America's Truck Drivers," was issued **April 28, 2025**, directing FMCSA to rescind the 2016 policy and issue new ELP enforcement guidance.
• On **May 20, 2025**, FMCSA issued an internal policy memorandum **restoring inspectors' authority to place a driver out of service** for failing to meet the ELP standard.
• The **Commercial Vehicle Safety Alliance (CVSA)** voted to add non-compliance with § 391.11(b)(2) to its **North American Standard Out-of-Service Criteria, effective June 25, 2025.**
• And it's no longer just policy: the **Consolidated Appropriations Act of 2026** (signed February 2026) contains a provision requiring FMCSA to update its regulations so that non-compliance with § 391.11(b)(2) triggers an out-of-service order. ELP-as-OOS is now backed by statute, not just executive guidance.

How it's assessed. Per FMCSA's guidance, inspectors begin the roadside inspection in English. If a driver appears unable to understand the initial instructions, the inspector conducts an ELP assessment — a driver interview conducted **entirely in English, without interpreters, cue cards, or translation apps.** A driver who can't meet the standard is placed out of service.

Here's the operational consequence that matters for vetting: an out-of-service order is an out-of-service order. When an ELP violation pulls a driver off the road, it becomes a **driver out-of-service event** that feeds the carrier's **driver OOS rate** and its **Driver Fitness BASIC.** A carrier whose drivers are getting placed OOS for ELP is a carrier whose driver-qualification process has a hole in it — and that shows up in the public data.

The Drug & Alcohol Clearinghouse now has real consequences

The second rule is the FMCSA **Drug & Alcohol Clearinghouse**, and it has quietly become one of the most consequential driver-qualification tools in the system.

The basics, since the first rule took effect **January 6, 2020:**

• The Clearinghouse is a secure federal database of CDL/CLP holders' **drug and alcohol program violations** — positive tests, refusals, and other violations.
• Employers must query it before hiring a CDL driver and **at least once per year** for current drivers.
• A driver with a violation is placed in **"prohibited"** status and cannot lawfully operate a commercial vehicle until they complete the **return-to-duty (RTD) process** under 49 CFR Part 40, Subpart O.

For the first few years, "prohibited" status was a serious problem for the employer's compliance — but a determined bad actor could sometimes keep driving by hopping carriers. That loophole is now closing, hard. The **"Clearinghouse II" rule took effect November 18, 2024**, and it changed the stakes:

• State Driver Licensing Agencies (SDLAs) must now query the Clearinghouse before issuing, renewing, upgrading, or transferring a CDL or CLP.
• And critically, **states must downgrade the CDL of any driver in "prohibited" status** — meaning a prohibited driver actually *loses the license* until they complete RTD and clear their status.

In other words: a drug or alcohol violation is no longer just an employment problem the driver might dodge by changing jobs. It now reaches the license itself. That's a structural tightening of driver qualification, and it surfaces in the **Controlled Substances/Alcohol BASIC** and in driver-qualification violations.

Why both of these show up in compliance investigations

Step back and notice what category both of these fall into: **driver qualification.** And driver qualification is exactly what FMCSA digs into during a compliance investigation.

When FMCSA investigates a carrier, it doesn't just glance at scores — it examines **acute and critical violations** (the categories defined in the safety-rating regulations) across the safety-critical areas: hours-of-service, vehicle condition, controlled substances/alcohol, and **driver qualification** (Part 391, which is where ELP and medical certification live). An investigation is where the granular, acute violations get pulled into the open — the missing driver-qualification file, the driver who shouldn't have been behind the wheel, the controlled-substances program gaps.

ELP and Clearinghouse violations are precisely the kind of driver-qualification problems that an investigation surfaces and that a roadside inspection now acts on immediately. They're not abstract paperwork issues — they pull trucks and drivers off the road.

A note on the out-of-service data — and how current it is

One thing worth getting right, because there's a lot of loose talk about it: FMCSA's roadside inspection and out-of-service data is **reasonably current** — it's collected at the roadside, loaded into FMCSA's systems, and refreshed regularly, so the picture you pull is close to a carrier's recent reality (not literally real-time, but far from stale). And the headline numbers are sobering on their own: across the big annual inspection blitzes, vehicle out-of-service rates run on the order of ~20% and driver out-of-service rates in the single digits — *before* you layer in the renewed ELP enforcement, which is pushing fresh attention onto the driver side of the ledger.

The point isn't a specific percentage. The point is that a meaningful share of the trucks and drivers inspected are found unfit to continue *that day* — and the data recording it is current enough to be useful at tender time.

Where this shows up before you tender — and in the app

Here's the practical payoff. ELP and drug/alcohol problems are driver-qualification failures, and driver-qualification failures are visible in a carrier's public FMCSA profile through three signals a careful screen already captures:

• The Driver Fitness BASIC — built from driver-qualification violations (licensing, medical, and now ELP-related driver OOS events feed the driver-side picture).
• The Controlled Substances/Alcohol BASIC — the category that reflects drug and alcohol program violations.
• The driver out-of-service rate — read against the national average, the share of a carrier's inspections where the *driver* (not the truck) was pulled off the road. ELP-as-OOS now contributes here.

These are exactly the signals DOTScreener pulls from the FMCSA record and freezes into the dated screening record. A carrier with an elevated driver OOS rate, a Driver Fitness BASIC alert, or a Controlled Substances/Alcohol alert is telling you — on the public record, before you tender — that its driver-qualification process has gaps. The app surfaces and documents those signals; it doesn't run the carrier's drug-testing program or conduct the ELP interview (those are the carrier's obligations and the inspector's job), but it makes sure that what the FMCSA record shows about driver qualification is part of your documented decision.

Two rules, both tightening, both landing on the driver side of safety. The trucks get the headlines, but the driver-qualification data — Driver Fitness, Controlled Substances, and the driver OOS rate — is where ELP and the Clearinghouse show their teeth. Screen it, read it against the averages, and keep the record.
