More Time to Weigh In: Car Fuel Rules Comment Period Stretches to February

Published Date: 1/14/2026

Proposed Rule

Summary

The government is giving folks more time—until February 4, 2026—to share their thoughts on new fuel-efficiency and safety rules for cars and light trucks from 2022 to 2031. This affects car makers and drivers by shaping future vehicle standards that balance safety, fuel savings, and costs. No extra public hearings will happen, but everyone’s invited to comment online or by mail before the deadline.
