Quick Overview

  • The Federal Motor Carrier Safety Administration (FMCSA) is seeking through a proposed rule to formally exempt English proficiency-related out-of-service penalties within the U.S.-Mexico border commercial zone. Theproposalis scheduled to be officially published on Monday.
  • The proposed rule notice codifies an April 2026memorandumthat clarified its English proficiency enforcement policy. In the memorandum, the agency stated that out-of-service penalties do not apply to drivers operating exclusively within the designated border commercial zone and provided guidance on how to enforce the policy.
  • "If there is evidence that a driver intends to operate outside the U.S. border commercial zone or has been operating a commercial motor vehicle (CMV) beyond it, this exemption does not apply," FMCSA said in the proposed rule.

In-Depth Analysis

The agency's April 2026 memorandum and its2025 standardstate that "federal inspectors" should not place drivers who remain within the U.S.-Mexico border commercial zone out of service.

FMCSA's April 2026 policy and proposed rule require agency enforcement personnel conducting inspections within the U.S.-Mexico border commercial zone "to determine the scope of the driver's current trip before deciding whether to issue an out-of-service order for an English proficiency violation," the notice states.

The April 2026 guidance "clarified how to apply the exemption to drivers stopped in the border commercial zone, noting that drivers stopped in the U.S.-Mexico border commercial zone whose current trip does not involve transportation beyond the U.S. border commercial zone should be cited but not placed out of service," Adrienne Gildea, deputy executive director of the Commercial Vehicle Safety Alliance (CVSA), said in an email to Trucking Dive.

The guidance provides several examples to clarify how the out-of-service criteria apply:

  • If a driver operates only within the U.S.-Mexico border commercial zone—for example, transporting goods from Laredo, Texas, to Nuevo Laredo, Mexico—an English proficiency violation does not constitute grounds for an out-of-service penalty.
  • However, if a driver operates outside the zone—for example, transporting goods from Laredo, Texas, to Detroit, Michigan, or from Nuevo Laredo, Mexico, to San Antonio, Texas—the driver may be placed out of service for an English proficiency violation.

The government standard further details how bills of lading, dispatch records, and other transportation documents can help assess these situations.

Existing English proficiencyregulations requirecommercial drivers to "be able to read and speak English sufficiently to communicate with the public, understand English highway traffic signs and signals, respond to official inquiries" and meet other objectives. According to 2025 FMCSA guidance (directed by a White House executive order), violations of this rule can lead toout-of-service penalties。

In advocating for the proposed rule, the agency estimated that unnecessary downtime could cost fleets up to $800 per day. FMCSA expects the measure to save the industry approximately $14 million annually, based on an estimated 9,000 drivers no longer being placed out of service.

Federal officials said in the notice that the proposed rule merely codifies existing policy and aligns with CVSA's North American Standard Out-of-Service Criteria, which added "enforcement tolerance" in an April 19, 2026 revision.

FMCSA's rule alignment reflects its own policy, even as it incorporates CVSA's broader support. On April 19, 2026, the CVSA board voted to revise its out-of-service criteria, replacing references citing FMCSA's May 2025 policy memorandum with "current FMCSA enforcement guidance," the agency's proposed rule states.

"By turning this guidance into codified rules, future administrations will not be able to weaken English proficiency requirements," the U.S. Department of Transportation said in apress release.
