English Proficiency Rule for Truck Drivers: Out-of-Service Checks
What 49 CFR 391.11(b)(2) requires, how inspectors run the two-step check, what an out-of-service order means for the driver and the carrier, and where the 2026 proposed rule stands.
Federal rule 49 CFR 391.11(b)(2) requires commercial drivers to read and speak English well enough to talk with the public, understand highway signs, answer officials’ questions and fill out records. Since June 25, 2025, a driver who fails that standard at a roadside inspection is placed out of service under the CVSA criteria. FMCSA proposed writing that consequence into its own rules in August 2026.
This guide reflects the rules and guidance in effect as of November 2026.
What does the English proficiency rule require?
The rule lists English proficiency as one of the basic qualifications to drive a commercial motor vehicle in interstate commerce. Under 391.11(b)(2), a driver must be able to read and speak English sufficiently to:
- converse with the general public;
- understand highway traffic signs and signals in English;
- respond to official inquiries; and
- make entries on reports and records.
The requirement itself is old; a version dates to the 1930s. What changed in 2025 was enforcement. From 2016 until 2025, inspectors could cite the violation but did not place drivers out of service for it. States that take federal Motor Carrier Safety Assistance Program grants must have compatible rules, so the standard also reaches most intrastate drivers. The text is in 49 CFR 391.11 on the eCFR.
Why are drivers being placed out of service now?
The change came in a few steps over 2025 and 2026:
| Date | Action |
|---|---|
| April 28, 2025 | Executive Order 14286 directs FMCSA to issue new enforcement guidance and seek out-of-service treatment |
| May 1, 2025 | CVSA votes to add English proficiency violations to the North American Standard Out-of-Service Criteria |
| May 20, 2025 | FMCSA policy memo MC-SEE-2025-0001 sets the roadside assessment procedure |
| June 25, 2025 | Out-of-service enforcement takes effect for federal and state inspectors |
| April 16, 2026 | FMCSA memo MC-SEE-2026-0002 narrows the exception for U.S.-Mexico border commercial zones |
| April 19, 2026 | CVSA ties its criteria to current FMCSA guidance, so the April 2026 memo applies to state inspectors |
| August 10, 2026 | FMCSA publishes a proposed rule to codify the out-of-service consequence; comments closed October 9, 2026 |
How do roadside inspectors test English proficiency?
Inspectors start every inspection in English. If the first contact suggests the driver may not understand the inspector’s instructions, the inspector runs a two-step assessment set out in FMCSA’s enforcement guidance:
- Driver interview. The inspector asks questions in English to judge whether the driver can respond to official inquiries.
- Highway sign recognition. If the driver passes the interview, the inspector checks whether the driver understands U.S. highway traffic signs in English, including electronic changeable message signs.
A driver who fails either step is cited under 391.11(b)(2). The FMCSA memos apply directly to federal inspectors; state inspectors follow the same procedure because the CVSA criteria point to current FMCSA guidance.
What happens to the driver after an out-of-service order?
The driver may not drive a commercial vehicle from that point. The carrier has to send a qualified driver to move the truck and load. The out-of-service order is recorded on the inspection report and in FMCSA’s data for both the driver and the carrier.
The order does not by itself cancel the CDL, which is a state document. Being placed out of service does not end the problem either: the driver remains unqualified under 391.11 until he or she can meet the standard, and FMCSA keeps its long-standing option to issue letters of disqualification and civil penalties. Driving in violation of an out-of-service order is a separate, serious offense covered in our guide to CDL disqualification offenses.
What does it mean for the carrier?
A motor carrier may not require or permit an unqualified person to drive (391.11(a)), so dispatching a driver who cannot meet the English standard exposes the carrier to violations and penalties. Roadside violations count in the carrier’s Driver Fitness data in the CSA Safety Measurement System.
On May 22, 2025, FMCSA also published guidance for carriers on assessing English proficiency during the driver qualification process. Brokers and shippers who check a carrier before tendering freight can see out-of-service history in public FMCSA data; our guide to checking a trucking company’s safety record shows where.
How many drivers have been placed out of service?
FMCSA’s own figures, published with the August 2026 proposal, show the scale. Between January 2025 and June 24, 2025, inspectors issued 7,812 English proficiency violations, and 33 led to out-of-service orders. Between June 25, 2025 and March 19, 2026, there were 60,399 violations and 19,045 out-of-service orders.
Every one of those out-of-service orders was issued outside the U.S.-Mexico border commercial zones. Under the 2025 guidance, drivers inspected inside those zones were cited but not removed from service.
What would the 2026 proposed rule change?
The proposed rule (91 FR 51422, docket FMCSA-2026-0826) would add 391.11(b)(2) to the regulatory definition of an out-of-service order and add a new paragraph saying a driver who fails the standard must be placed out of service immediately. FMCSA says the proposal responds to a CVSA petition and aligns its rules with the criteria already used at roadside.
It would also write the border-zone exception into the rule in its narrower 2026 form. A driver inspected in a border commercial zone would still be cited, but placed out of service only if the current trip takes the driver into the United States beyond the zone. As of November 2026 the comment period has closed and no final rule has been published. The proposal is on the Federal Register.
Bottom line
Out-of-service enforcement is already in force through the CVSA criteria, so the pending rule changes little at the roadside outside the border zones. Its practical effect would be to make every state adopt a compatible requirement in state law, whatever CVSA decides later. Carriers that hire drivers with limited English carry the risk of a stranded load and a Driver Fitness violation on every inspection.
FAQ
Can I use a translation app during an inspection?
The rule measures your own ability to speak and read English, so a translation app does not show that you meet it. Ask your carrier how it expects you to handle inspections before you are dispatched.
Does the rule apply to intrastate drivers?
The federal rule covers interstate drivers. States receiving federal safety grants must adopt compatible rules, which generally extend the same qualification to intrastate commercial drivers.
Is an English proficiency failure a CDL disqualification?
Not automatically. It is an out-of-service violation, and FMCSA can pursue a separate disqualification action. Your state CDL stays valid unless the state acts on it.
Is the proposed rule final?
No. As of November 2026 it is a proposal, with comments closed on October 9, 2026. The out-of-service consequence already applies through the CVSA criteria.
