English proficiency requirement for truck drivers, answered
The rule has been on the books since the 1930s. Since June 2025, failing it at an inspection ends the driver's trip, and FMCSA has now proposed writing that consequence into the regulations.

English proficiency enforcement in numbers
The English proficiency requirement for truck drivers, 49 CFR 391.11(b)(2), says a driver must read and speak English well enough to talk with the public, understand highway signs, answer official questions, and fill out records. Since June 25, 2025, a driver who fails the roadside check is placed out of service.
For a carrier, an English proficiency out-of-service order is a driver qualification problem that surfaced at the roadside. The rule itself has barely changed since the 1930s. The enforcement has.
I lead operations at Simplex, and I treat English proficiency the way I treat any other qualification: a documented check before the first dispatch, not a hope at the scale.

Key takeaways
The standard is 49 CFR 391.11(b)(2)
Drivers must read and speak English well enough to converse with the public, understand highway signs, respond to official inquiries, and make entries on records.
Failing it means out of service
Since June 25, 2025, CVSA's out-of-service criteria treat a violation as a driver out-of-service condition, not just a citation.
The roadside check has two steps
An interview answered in English, then highway sign recognition. Interpreters, cue cards, and phone apps are not allowed in the interview.
There is no certificate or official test PDF
The regulation names abilities, not a level, and FMCSA has not published the inspectors' question list.
The rule is being written into the regulations
FMCSA proposed codifying the out-of-service consequence on August 10, 2026. Comments close October 9, 2026.

What is the English proficiency requirement for truck drivers?
Under 49 CFR 391.11(b)(2), a person is qualified to drive a commercial motor vehicle only if they can read and speak English well enough to:
- Converse with the general public
- Understand highway traffic signs and signals in English
- Respond to official inquiries
- Make entries on reports and records
It is a driver qualification, like minimum age or a valid license, and 391.11(a) bars a carrier from requiring or permitting an unqualified person to drive. The Interstate Commerce Commission first set the requirement in its 1936 safety rules. What changed in 2025 was enforcement.
The federal rule governs interstate drivers. Every state takes part in FMCSA's Motor Carrier Safety Assistance Program and must keep compatible rules, which generally reach intrastate drivers too.
Is there a required English level or certificate?
No. The regulation names abilities, not a score, a language level such as B1, or a certificate. The question is functional: can the driver respond to an inspector and understand highway signs in English?
One carve-out: under FMCSA guidance from 2014, a driver with an FMCSA exemption from the hearing standard meets the requirement if they can read and write English, even without speaking it.
How is English proficiency enforced in 2026?
Since June 25, 2025, a driver who fails the English proficiency assessment during an inspection is placed out of service, not just cited. Before that, a 2016 FMCSA policy had inspectors cite the violation only. Here is how the change happened, and where it stands as of September 2026.
| Date | What happened |
|---|---|
| April 28, 2025 | Executive Order 14286 directs FMCSA to restore out-of-service enforcement |
| May 20, 2025 | FMCSA issues roadside policy MC-SEE-2025-0001, rescinding its 2016 cite-only policy |
| June 25, 2025 | CVSA's out-of-service criteria make a 391.11(b)(2) violation a driver out-of-service condition |
| February 3, 2026 | Public Law 119-75, Sec. 131, directs DOT to update its regulations so noncompliance triggers an out-of-service order |
| April 16, 2026 | Revised policy MC-SEE-2026-0002 narrows the U.S.-Mexico border-zone exception; CVSA adopts it April 19 |
| August 10, 2026 | FMCSA proposes adding the out-of-service consequence to 49 CFR 391.11; comments close October 9, 2026 |
The effect showed up in the data. FMCSA counted 7,812 English proficiency violations in 2025 through June 24, with 33 out-of-service orders. From June 25, 2025 to March 19, 2026, it counted 60,399 violations and 19,045 out-of-service orders.
During International Roadcheck, May 12 to 14, 2026, inspectors placed 361 U.S. drivers out of service for English proficiency: 9.5% of U.S. driver out-of-service violations, the fourth most common reason.
What happens in a DOT English proficiency test?
There is no written exam. Under FMCSA's current roadside policy, inspectors start every inspection in English and run a two-step assessment only if the first contact suggests the driver may not understand their instructions. It can happen during any of the CVSA inspection types that include the driver.
Step 1: The driver interview
The inspector asks questions in English, and the driver must answer in English. Interpreters, I-Speak cards, cue cards, phone apps, and telephone interpretation are not used in this step, because they can mask the gap. Inspectors are told to speak slowly but naturally and to rephrase in English.
A driver who cannot respond sufficiently is cited, and the assessment stops there.
Step 2: Highway sign recognition
A driver who passes the interview is asked to explain U.S. highway signs from the Manual on Uniform Traffic Control Devices, plus electronic changeable message signs. In April 2026, FMCSA removed signs with little or no lettering from its examples, so the step tests reading English, not only recognizing symbols.
Where are the actual test questions?
FMCSA has not published them. The inspector question list and sign examples are redacted in the public version of the policy, so no official test questions PDF exists. FMCSA's hiring guidance for carriers does suggest interview topics: a recent or planned trip, time on duty and the logbook, the driver's license, shipping papers, and vehicle equipment subject to inspection.
The check happens wherever an inspection does, including weigh stations. Texas DPS, for example, says its inspectors run English proficiency evaluations during routine traffic stops and at weigh stations.
What is the border-zone exception?
In the commercial zones along the U.S.-Mexico border, a driver who fails is cited but not placed out of service, only when the current trip stays inside those zones. If the trip went or will go beyond them, such as a Laredo pickup bound for Detroit, the driver is placed out of service.
What happens if a driver fails the English proficiency check?
Outside the border-zone exception, the driver is placed out of service immediately and told not to drive a commercial vehicle in interstate commerce until the condition is remedied. The inspector documents the driver's responses as evidence.
FMCSA can go further. When warranted, it may start a driver qualification proceeding by issuing a letter of disqualification under 49 CFR 386.11(a).
For the carrier, the load needs another driver, and the violation goes on its inspection record. FMCSA notes that repeated violations can hurt a carrier's Safety Measurement System results. If you believe a violation was recorded in error, our guide to recovering from a DOT violation covers the next steps.
What a carrier cannot do is dispatch the same driver again as if nothing happened. Under 391.11(a), a carrier may not permit an unqualified person to drive.
Does the CDL test have to be in English?
The skills test does. Under 49 CFR 383.133(c)(5), interpreters are prohibited, the applicant must understand and respond to the examiner's commands in English, and neither side may use another language during the test.
Federal rules still let states give the knowledge test in a foreign language, as long as no interpreter is used. Some states have dropped that option: Texas has given CDL and CLP knowledge tests only in English since June 1, 2026. Our Texas commercial driver handbook guide covers the Texas details.
Passing the CDL tests does not settle the question for good. The roadside assessment is a separate check of the same qualification, made whenever an inspector has reason to run it.
How can carriers and CDL drivers prepare?
FMCSA expects carriers to assess English proficiency as part of driver qualification, before dispatch, and its May 2025 guidance describes how. It fits into the hiring sequence alongside the other checks.
Step 1: Interview in English at hiring
A manager asks, in English, about a recent or planned trip, time on duty and the logbook, the driver's license, shipping papers, and the vehicle equipment subject to inspection. No interpreters or apps for this part. Once the assessment is done, the rest of the interview can continue in another language.
Step 2: Check highway sign comprehension
Choose signs from the MUTCD and examples of electronic message signs, and ask the driver to explain them. FMCSA's hiring guidance allows the explanation in any language the manager understands. Don't assume an inspector will allow the same; that part of the roadside procedure is not public.
Step 3: Record the result
Write down who assessed the driver, when, and the outcome, and keep it with the driver qualification file. The regulation does not list this record, but it shows the check was made.
Step 4: Build English for CDL drivers around the job
FMCSA does not require carriers to train drivers in English, but carriers are free to. The most useful practice mirrors the interview: answering questions about the trip, hours, license, paperwork, and equipment out loud, in English, without notes, and reading worded road signs.
