Federal Motor Vehicle Safety Standards; Federal Motor Carrier Safety Regulations: Parts and Accessories Necessary for Safe Operation; Speed Limiting Devices; Withdrawal

Transportation

Summary

The National Highway Traffic Safety Administration is proposing to withdraw a previous rule that required heavy trucks and buses to have speed-limiting devices installed to prevent them from driving too fast. This change means the government is reconsidering whether these safety devices should still be mandatory for commercial vehicles.

Key Points

  • 1The rule being withdrawn previously required large trucks and buses to have devices that electronically limit their maximum speed for safety reasons
  • 2This is a proposed withdrawal, meaning the agency is suggesting the rule should be removed rather than kept in effect
  • 3The change primarily affects commercial truck and bus operators who would no longer be required to install speed limiters in their vehicles
  • 4This regulation falls under federal motor vehicle safety standards and motor carrier safety rules that govern commercial transportation
  • 5The public and interested parties can comment on whether this withdrawal is a good idea before the rule change becomes final

Impact Assessment

If you are a transportation company or truck operator, this means you may no longer be required to install speed-limiting devices on heavy trucks and buses, potentially reducing equipment costs but possibly increasing safety risks on highways.
