Overview Of 2025 Trucking Law Changes
The Federal Motor Carrier Safety Administration (FMCSA) and the Department of Transportation (DOT) are implementing several key regulations in 2025:
These changes will affect carriers of all sizes, from owner-operators to large fleets. Many regulations will require updating equipment, adjusting operations, or completing additional documentation to maintain compliance.
With increased roadside inspection activities scheduled throughout 2025, staying informed about these changes is essential. For more detailed information about DOT inspections in 2025, visit the OTR Solutions DOT Blitz Week guide. Speed Limiter Mandate For Commercial Vehicles
According to the FMCSA’s official regulatory agenda, the agency is working on a speed limiter rule for commercial vehicles. The proposed rule would affect trucks weighing over 26,000 pounds that have electronic control units capable of limiting speed.
While the final speed threshold hasn’t been officially announced, the rule aims to reduce crash severity and improve overall highway safety. The FMCSA has pushed the publication date of the proposal to May 2025, indicating careful consideration of industry feedback.
For carriers, this will likely mean:
Mandatory English Proficiency For All Truck Drivers
The FMCSA continues to enforce its regulation under 49 CFR 391.11(b)(2), which requires commercial drivers to “read and speak the English language sufficiently to converse with the general public, understand highway traffic signs and signals, respond to official inquiries, and make entries on reports and records.”
This longstanding requirement is being emphasized in 2025 with clearer enforcement guidelines. The regulation applies to all drivers operating commercial vehicles in interstate commerce, including cross-border drivers from Canada and Mexico.
Carriers should ensure their drivers can:
Enhanced CDL Reviews For Non-Domiciled Drivers
The FMCSA is strengthening its review process for Commercial Driver’s Licenses (CDLs) issued to non-domiciled drivers. This initiative aims to ensure consistent safety standards across all commercial drivers operating on U.S. roads.
This increased scrutiny will include:
Transportation companies employing drivers with non-domiciled CDLs should prepare for these enhanced reviews by maintaining comprehensive driver qualification files and allowing additional time for license processing.
New Safety Technology Requirements
Based on the Bipartisan Infrastructure Law and FMCSA proposals, several safety technologies will become mandatory for commercial vehicles:
Electronic Stability Control (ESC) systems will be required for a broader range of heavy vehicles. These systems help prevent rollovers and loss-of-control crashes by automatically applying selective braking.
Automatic Emergency Braking (AEB) systems will also be mandated for new commercial vehicles. As described in theFMCSA’s proposed rule, AEB systems use sensor technologies to detect potential crashes and automatically apply braking when necessary.
The final rule was published in January 2025, with implementation now being phased in based on vehicle class and weight ratings. Class 7-8 trucks (over 26,000 pounds) must comply by 2027, while Class 3-6 vehicles must comply by 2028.
Changes To Medical Examiner Certification Reporting
The FMCSA is implementing a more integrated electronic system for medical examiner certification reporting. This change will streamline the connection between medical certification results and state CDL systems.
Benefits of this new system include:
Carriers should establish systems to track medical certification expiration dates and ensure drivers complete examinations with enough time to address any issues that might affect their driving status.
Updated Physical Qualification Standards For Drivers With Epilepsy
The FMCSA has revised its medical qualification standards for drivers with epilepsy or seizure disorders. These updated guidelines maintain safety standards while expanding opportunities for qualified individuals.
The revised standards include specific requirements for:
Carriers should familiarize themselves with these updated standards to ensure proper documentation while potentially accessing a broader pool of qualified drivers.
Elimination Of MC Numbers In Favor Of USDOT Numbers
The FMCSA is launching a new registration system in 2025 that will complete the transition from MC (Motor Carrier) numbers to USDOT numbers as the primary identifier for all carriers. This change is scheduled to take place by October 1, 2025.
According to official FMCSA information, the new system “will simplify the registration process, streamline identification, improve the user experience, and incorporate enhanced verification tools.”
This change will require updates to:
Companies should begin this transition early to ensure all materials and systems are updated before the official changeover.

The FMCSA is implementing a more integrated electronic system for medical examiner certification reporting. This change will streamline the connection between medical certification results and state CDL systems.
Benefits of this new system include:
- Reduced paperwork burden for drivers and carriers
- Elimination of potential fraud through direct electronic submission
- Faster processing of medical qualification information
- More consistent enforcement of health standards
Carriers should establish systems to track medical certification expiration dates and ensure drivers complete examinations with enough time to address any issues that might affect their driving status.

The revised standards include specific requirements for:
- Medical documentation and history
- Seizure-free periods under medical supervision
- Regular neurological evaluations
- Ongoing monitoring protocols
Carriers should familiarize themselves with these updated standards to ensure proper documentation while potentially accessing a broader pool of qualified drivers.
