Electric Vehicle Safety Rules Hit Snooze Until March
Published Date: 2/14/2025
Rule
Summary
The government is pushing back the start date for new safety rules on electric vehicles to March 20, 2025. These rules, called FMVSS No. 305a, make sure electric cars and trucks have safer batteries and provide emergency responders with important info. This delay gives manufacturers and responders more time to get ready without any extra costs right now.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
FMVSS No. 305a Replaces No. 305
FMVSS No. 305a replaces FMVSS No. 305 and applies to light and heavy vehicles. The new standard includes performance requirements for the propulsion battery.
Compliance Date Pushed to March 20, 2025
The agency delayed the effective date of the December 20, 2024 final rule until March 20, 2025. That delay (and the delayed approval of referenced publications) gives vehicle manufacturers more time before FMVSS No. 305a’s requirements take effect.
Emergency-Response Documentation Requirement Delayed
The final rule created 49 CFR part 561, which requires manufacturers to compile risk mitigation documentation and submit standardized emergency response information to assist first and second responders. Because the rule’s effective date is delayed until March 20, 2025, those documentation and submission requirements will also be delayed until that date.
