Starting June 25, 2025, commercial truck drivers in the United States who fail to demonstrate sufficient English proficiency during roadside inspections will be immediately placed “out of service,” a measure that significantly tightens the enforcement of a long-standing federal regulation.
The new guidance requiring commercial truck drivers to master the English language, driven by a presidential executive order and formalized by the U.S. Department of Transportation (USDOT) and the Federal Motor Carrier Safety Administration (FMCSA), aims to bolster road safety across the country.
What Does the Measure Entail?
The federal regulation, specifically 49 CFR § 391.11(b)(2), has long required commercial truck drivers to be able to read and speak English well enough to:
- Converse with the general public.
- Understand road signs and traffic signals.
- Respond to questions and instructions from officers (police, customs agents, inspectors).
- Make entries in reports and records (such as travel logs and inspection reports).
The novelty is not the rule itself, but its strict enforcement starting in June 2025. Under the new guidelines, officers conducting roadside inspections (at rest stops, weigh stations, or roadside) will assess drivers’ English proficiency through a two-step process:
- Conversational Interview: The officer will begin the inspection and ask questions in English about the trip, the cargo, the driver’s documents, or the vehicle’s condition. The driver must respond in English without the help of translators, mobile apps, or any other type of assistance.
- Traffic Sign Identification: If the driver passes the interview, the officer may proceed to evaluate their ability to read and understand standard U.S. traffic signs.
The goal is not to assess perfect fluency, but a functional ability that ensures safe vehicle operation and effective communication in critical situations.
Consequences of Not Speaking English
The primary and most immediate consequence for drivers who fail this English assessment is being placed out of service (OOS).
This means that:
- The driver cannot continue operating the truck. The order takes effect immediately.
- The vehicle is immobilized until the transportation company can send another driver who meets the language requirement to continue the trip.
- A violation will be recorded on the driver’s and the carrier’s record, which may affect their safety ratings and potentially their insurance premiums.
In more serious or repeated cases, the FMCSA could take action to disqualify the driver from operating commercial vehicles in interstate commerce.
This new policy represents a significant shift from previous years, when a lack of English proficiency rarely resulted in an out-of-service order. Now, the administration aims to eliminate what it considers a risk to road safety, ensuring that all commercial drivers can understand and respond appropriately to laws, signs, and authorities on U.S. roads.
