FMCSA Proposes Rule to Make English Proficiency a Permanent 'Out-of-Service' Violation for Truck Drivers

The Federal Motor Carrier Safety Administration (FMCSA) has officially proposed a rule to permanently codify English language proficiency as an out-of-service violation for commercial truck drivers. Announced by U.S. Transportation Secretary Sean P. Duffy in August 2026, the rulemaking aims to write the severe consequence directly into federal safety regulations. This move closes a long-standing gap between what the standard requires and how it is enforced at the roadside, ensuring that drivers who cannot communicate with inspectors are immediately sidelined.[1][3]

The underlying requirement is far from novel; English language proficiency has been a federal driver qualification standard since 1937. Under Title 49, Code of Federal Regulations (CFR) 391.11(b)(2), an interstate commercial motor vehicle driver must be able to read and speak English well enough to carry out specific safety and recordkeeping duties. This includes conversing with the general public, understanding highway traffic signs, responding to official inquiries, and making entries on reports and logs.[4][5]

Despite the law's longevity, its enforcement has fluctuated wildly depending on the administration in power. In 2016, the FMCSA adopted a softer enforcement approach, downgrading the violation to a simple civil penalty. Under that guidance, inspectors could cite a driver for lacking English skills, but they were not directed to place the driver out of service, allowing them to drive away with a warning.[3][5]

That leniency ended abruptly in April 2025, when a presidential executive order directed the agency to reinstate strict enforcement. Following the order, the Commercial Vehicle Safety Alliance (CVSA)—the body that governs roadside inspection standards across North America—utilized an emergency bylaw provision to add English proficiency back to its out-of-service criteria, effective June 25, 2025.[5]

Now, the Department of Transportation is taking the final step to lock that strict enforcement into law. By codifying the rule, the DOT intends to prevent future administrations from quietly weakening the standard via internal agency memos. Secretary Duffy emphasized that the rule ensures roadside inspectors will always have the full force of federal regulation behind them to issue immediate out-of-service orders.[3]

The scale of the enforcement shift is already evident in the data. According to the DOT, since the strict enforcement was reinstated in 2025, more than 26,000 commercial drivers have been placed out of service for failing the proficiency evaluation. Federal regulators argue that drivers who cannot read a "Steep Grade" or "Runaway Truck Ramp" sign pose an unacceptable and preventable risk when operating 80,000-pound vehicles on public highways.[1][3]

For fleet owners, safety managers, and independent owner-operators, the proposed rule shifts compliance from a moving target to a hardcoded operational reality. Roadside inspectors evaluate a driver's proficiency using a practical, two-step process during standard weigh-station or roadside stops. The evaluation is designed to test functional safety communication, not perfect grammatical fluency.[5]

First, the law enforcement officer asks the driver standard questions in English to gauge basic conversational ability and comprehension. Next, the driver is asked to identify and explain standard traffic signs pulled directly from the Manual on Uniform Traffic Control Devices (MUTCD). Failing either step results in an immediate out-of-service order, meaning the truck cannot move until a qualified, English-speaking driver arrives to take over the load.[5]

The rulemaking also specifically targets cross-border freight operations, closing a major enforcement loophole at the U.S.-Mexico border. Under the proposed guidelines, any driver who fails the English-language evaluation must be placed out of service before they are permitted to travel beyond the designated commercial border zone. This ensures that unqualified foreign-domiciled drivers cannot transit further into American communities.[1][2]

Driver training organizations have strongly backed the proposal, framing it as a necessary baseline for professional instruction. The Commercial Vehicle Training Association (CVTA) issued a statement supporting the rule, noting that reading the road and communicating without hesitation are fundamental safety skills, not political talking points. The CVTA emphasized that quality entry-level driver training programs already build their curriculums around these exact federal standards.[6]

For industry training groups, making the consequence clear and consistent across all states levels the playing field. It ensures that all commercial drivers are held to the same rigorous professional standards, regardless of where they were licensed, and prevents the regulatory confusion that arises when enforcement tolerances shift from year to year.[6]

With the public comment period open until October 9, 2026, motor carriers are being urged to proactively audit their driver pools and hiring practices. Fleets that fail to ensure their drivers can operate safely in an English-speaking environment risk severe supply chain disruptions. An out-of-service order not only delays freight and damages customer relationships, but it also negatively impacts a carrier's federal safety rating, leading to higher insurance premiums and increased regulatory scrutiny.[2][4]
