Rulemaking Delays: What to Expect for Speed Limiter and AEB Regulations

Press Center

The rulemaking process for significant safety regulations affecting commercial motor vehicles has experienced delays. Two key rules, the speed limiter rule and the automatic emergency braking (AEB) systems rule, have been postponed, affecting timelines and compliance requirements for fleet operators.

Speed Limiter Rule Delays

The speed limiter rule, initially proposed in 2016 by the National Highway Traffic Safety Administration (NHTSA) and the Federal Motor Carrier Safety Administration (FMCSA), has been delayed with a new proposed publication date set for May 2025. This rule aims to establish speed limits for commercial motor vehicles (CMVs) with a gross vehicle weight rating (GVWR) of 26,001 pounds or more. Once published, the rule will specify the speed limit and initiate another comment period, allowing stakeholders to provide input before finalization.

Automatic Emergency Braking (AEB) Systems Rule Delays

Another critical rulemaking process involves the implementation of automatic emergency braking (AEB) systems on heavy trucks. This joint rulemaking effort by NHTSA and FMCSA aims to set performance standards, maintenance requirements, and test procedures for AEB systems. Initially scheduled for publication this year, the rule has been delayed until January 2025. The rule will mandate AEB systems for heavy trucks, enhancing safety and reducing collision risks.

Implications of Rulemaking Delays

These delays impact the timeline for compliance and preparation for fleet operators. Understanding the new timelines and the expected requirements is crucial for staying ahead in the industry.

Preparing for the Speed Limiter Rule

  • Stay Informed: Keep abreast of updates from NHTSA and FMCSA regarding the proposed speed limiter rule.
  • Prepare Your Fleet: Evaluate current fleet capabilities and plan for necessary adjustments once the speed limit is determined.
  • Engage in the Comment Period: Use the upcoming comment period to provide feedback and influence the final rule.

Preparing for the AEB Systems Rule

  • Understand AEB Technology: Familiarize yourself with AEB systems, their benefits, and their operation.
  • Plan for Maintenance: Develop a maintenance plan for AEB systems to ensure compliance with upcoming regulations.
  • Monitor Regulatory Updates: Keep track of updates on performance standards and test procedures for AEB systems.

Final Thoughts

Rulemaking delays for the speed limiter and AEB systems regulations provide additional time for preparation and compliance. Staying informed and proactive will ensure your fleet is ready to meet the new safety standards when they are implemented.

Remember, proactive preparation and engagement during the comment periods are key to navigating these regulatory changes successfully.
