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- 1The rule being withdrawn previously required large trucks and buses to have devices that electronically limit their maximum speed for safety reasons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
