Government Pushes Back Car Auto-Braking Safety Mandate Date

Published Date: 1/27/2025

Rule

Summary

The government is pushing back the start date for new rules that require all new light vehicles to have automatic emergency braking and collision warning systems. This delay gives car makers more time to get ready before the rules kick in. If you’re buying a new car soon, these safety features will be standard—but just a bit later than planned.

Analyzed Economic Effects

2 provisions identified: 1 benefits, 1 costs, 0 mixed.

Automakers Given More Time to Comply

The delay gives car manufacturers more time to meet the FMVSS No. 127 requirements for automatic emergency braking (AEB), pedestrian AEB (PAEB), and forward collision warning (FCW) on all new light vehicles. The document explicitly states the effective date of the November 26, 2024 final rule is being pushed back to allow more time for industry readiness.

Mandatory AEB Start Date Delayed

The agency delayed the effective date of the November 26, 2024 final rule that implements FMVSS No. 127. FMVSS No. 127 requires automatic emergency braking (AEB), pedestrian AEB (PAEB), and forward collision warning (FCW) systems on all new light vehicles, so these safety features will become standard on new cars but later than originally scheduled.
