  • Would block the Environmental Protection Agency from writing or enforcing any federal rule that requires these emissions parts on vehicles or engines.

    From policy text

What Happens Next

Projected impacts based on AI analysis

As soon as the bill becomes law

Federal requirements for emissions-control devices and onboard diagnostics on vehicles/engines stop being enforceable

Diesel owners and manufacturers would no longer face federal rules forcing installation, certification, or maintenance of these systems; federal penalties tied to these requirements would stop going forward

Immediately after the bill becomes law

EPA rules on installing/removing/maintaining emissions-control devices are treated as having no force or effect

Companies and vehicle owners would not have to follow those federal regulations anymore, though state rules could still matter
