Thinking Process:

1. **Deconstruct the Source:**
* *Topic:* NHTSA developing a proposal for impaired driving prevention technology in new passenger vehicles.
* *Action:* Advance Notice of Proposed Rulemaking (ANPRM) released Jan 5.
* *Scope:* Passenger vehicles only. Explicitly excludes Commercial Motor Vehicles (CMVs).
* *Stats:* 13,384 lives lost in drunk driving incidents in 2021.
* *Quotes/Notes:* "Alcohol-impaired driving is a major cause..." NHTSA involved since 1970s. Tech presents new opportunities.
* *Tech Challenges:* Distinguishing impairment states, false positives, prevention measures.
* *Exclusions:* Drugged driving excluded due to "technology immaturity and lack of testing protocols."
* *Legal Basis:* 2021 Infrastructure Investment and Jobs Act directives. National Traffic Motor Vehicle Safety Act requirements.
* *Comment Period:* 60 days starting Jan 5. Privacy/security concerns, consumer acceptance.
* *Docket:* NHTSA-2022-0079 on regulations.gov.
* *Source Date/Context:* Source mentions Jan 5 release. Current date is Sept 9, 2026. This suggests the event happened in the past relative to "Today," or the source is old and the rewrite needs to frame it as current news or recent development. *Wait, the prompt says "TODAY: September 9, 2026". The source mentions "Jan 5". If the source is from Jan 5, 2026, that's about 8 months ago. If the source is from Jan 5, 2025, it's over a year ago. Usually, in these prompts, the "TODAY" date is the publication date. The source text says "released... on Jan. 5". It doesn't give a year in the text body, just "Jan 5". However, the docket number "NHTSA-2022-0079" suggests the docket opened in 2022. An ANPRM usually happens before a rule. If the docket is 2022, and the ANPRM is Jan 5, it could be Jan 5, 2023, or Jan 5, 2024, or Jan 5, 2025. Given "TODAY" is Sept 9, 2026, writing this as "New Impaired Driving Mandate May be on the Docket" suggests it's fresh news. I should treat the "Jan 5" as recent relative to the article's context, or perhaps the source is a recap. *Crucial Check:* The source says "released an advance notice... on Jan. 5". If I'm writing on Sept 9, 2026, and the source is the only input, I must assume the source is the news being reported. The date discrepancy (Jan vs Sept) might mean this is a follow-up or the "Jan 5" is from the current year (2026) and the article was written in Jan, but the user is asking for a rewrite *now*? Or is the "Today" date just a constraint for the output metadata? Usually, the rewrite should reflect the news as if it's happening or just happened. If the source says "Jan 5", and today is "Sept 9", and the title is "New... May be on the Docket", it implies the news is current. I will write the dateline as Washington, D.C., and reference the Jan 5 date as the trigger event, perhaps noting the comment period or the ongoing nature. *Actually, looking at the docket NHTSA-2022-0079, that's a real docket. The ANPRM was published in Jan 2023 or 2024? A quick mental check (simulation): NHTSA-2022-0079 is likely the docket
