FMCSA English Proficiency Rule: How the Roadside Test Works and What Carriers Need to Know (2026)

Reviewed by Austin Park, founder of ICR Filings · Updated October 28, 2026

English language proficiency, or ELP, is one of the most searched trucking topics this fall, and for good reason. A driver who cannot pass the roadside check is placed out of service on the spot, which stops the load, the truck, and the revenue. Here is what the rule says, how the check works, what FMCSA proposed in August 2026, and what owner-operators and small fleets should do now.

What the rule says

Under 49 CFR 391.11(b)(2), a person may drive a commercial motor vehicle in interstate commerce 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

The requirement itself is old. FMCSA traces it to 1937. Section 391.11(a) also puts it on the company: a motor carrier may not require or permit someone to drive unless that person is qualified.

What changed in 2025

1. 2015 to 2016The violation was dropped from the out-of-service criteria, and a 2016 FMCSA policy stopped inspectors from placing drivers out of service only for ELP. Drivers got a citation and kept driving.
2. April 28, 2025Executive Order 14286 directed FMCSA to rescind the 2016 policy and issue new enforcement guidance.
3. May 20, 2025FMCSA issued new ELP enforcement guidance to its inspectors.
4. June 25, 2025ELP violations became out-of-service violations under the North American Standard Out-of-Service Criteria.
5. April 16, 2026FMCSA updated its guidance on trips inside the U.S.-Mexico border commercial zones and published FAQs.
6. August 10, 2026FMCSA proposed writing the out-of-service rule into the regulations (comments closed October 9, 2026).

How the roadside check works

1. 1
   The inspection starts in English

   FMCSA's guidance tells inspectors to begin every roadside inspection in English.
2. 2
   Step 1: the interview

   If the driver seems not to understand, the inspector asks questions to see whether the driver can respond to official inquiries.
3. 3
   Step 2: highway signs

   A driver who passes the interview then takes a highway traffic sign recognition test, including electronic message signs in English.
4. 4
   Fail either step: out of service

   The driver is placed out of service and cannot keep driving. The truck needs a qualified driver to move.

The numbers

Enforcement is also showing up in targeted operations. In Operation Saturday Night Fever on September 26, 2026, officers in South Carolina, North Carolina, Florida, and Georgia did 552 inspections and placed 78 drivers out of service, 12 of them for ELP.

What the August 2026 proposed rule would do

• Write the out-of-service consequence into 49 CFR 390.5, 390.5T, and 391.11, so it no longer depends only on the out-of-service criteria.
• Make every state apply the same standard, since states that receive MCSAP funding must adopt compatible rules.
• Keep one limited exception: a driver whose current trip stays entirely inside the U.S.-Mexico border commercial zones is cited, not placed out of service, unless there is evidence they have gone or plan to go beyond the zones.

FMCSA says the proposal creates no new requirement, because drivers are already placed out of service under the current criteria. As of late October 2026 the rule is still a proposal.

The other driver rule in the news: non-domiciled CDLs

Searches for non-domiciled CDLs are rising too. FMCSA's final rule, effective March 16, 2026, limits new and renewed non-domiciled CDLs and learner's permits to drivers in certain employment-based statuses (H-2A, H-2B, and E-2), plus a few cases tied to U.S. territories and decertified state programs. If you or a driver holds one, check with your state licensing agency about your own license before it comes up at the roadside.

What carriers and owner-operators should do

• Treat it as a hiring check. English proficiency is a driver qualification, the same as a valid CDL and a medical card. Your company is responsible for not letting an unqualified driver drive.
• Plan for an out-of-service stop. In its own cost estimate, FMCSA assumes about two days to get a replacement driver to the truck and the freight moving again.
• Keep your records clean. An out-of-service driver violation lands on your company's record and your driver out-of-service rate. If an inspection was recorded wrong, use DataQs.
• Know what your record shows. Read your FMCSA company snapshot the way a broker does.
