NHTSA Is 10 Rules Behind Congress and 236 Employees Short. The Backlog Has a Body Count.

On September 5, Automotive News published the count nobody at NHTSA wanted to see in print: the agency has proposed delaying at least 18 vehicle safety tests, while at least 10 rules Congress ordered it to write sit past their statutory deadlines.^[1] I pulled the agency’s own reports to price the backlog, and the invoice is written in bodies.

Start with the docket, because the docket is the crime scene. Between 2012 and 2015, Congress ordered NHTSA to issue 22 rules; by 2022, six were done, and every one missed its deadline.^[2] As of the agency’s own December 2024 report to Congress, 19 rules were still pending; across three authorization acts the agency had finished 38 of 57 mandates.^[2][4] That is a one-third failure rate on homework assigned by law.

Then the staffing, because arithmetic is undefeated: NHTSA peaked at 790 employees in 2024 and was down to 554 by January.^[2] Its budget request cut funding 6.8 percent, and Congress appropriated $23 million less than even that reduced number.^[2] Congress keeps assigning term papers and repossessing the typewriter, then holds hearings about the missing papers.

Now the per-rule math, which is where it gets grim. Consider the impaired-driving detection mandate, Section 24220 of the infrastructure law, with a final-rule deadline of November 15, 2024; it is now more than 660 days late.^[1] Alcohol killed 11,904 Americans on the roads in 2024.^[6] Worse, the heavy-truck speed limiter rule was not merely delayed but withdrawn in January, and the agencies’ own 2016 analysis said it would prevent 1,115 fatal crashes a year.^[7] Meanwhile the hot-car rule is two and a half years late, and about 37 children die in hot cars in an average year.^[8] The backlog’s addressable toll: roughly 13,000 lives a year, every year.

For contrast, look at the one they finished. FMVSS 127, automatic emergency braking with pedestrian detection, was finalized in April 2024 and takes full effect in September 2029, projected to save at least 360 lives and prevent 24,000 injuries a year.^[5] Finished rules work, which is exactly the point. Strip away the jargon and the backlog is a funding decision wearing a policy’s clothes.

Give the honest objections their full weight. On impaired driving, the technology may genuinely not exist yet: NHTSA’s March 2026 report to Congress admits no commercial system can passively detect impairment at the required accuracy, and a rule mandating the impossible would strand sober drivers at the grocery store.^[1] Rulemaking has a speed limit of its own, since rushed rules die in court and save nobody; the Administrative Procedure Act demands notice, comment, and judicial review. And the 13,000 figure is the addressable pool, not the yield: fleet turnover takes a decade and a half, so a rule issued on time in 2024 would not have saved its first life before 2028. Blaming the backlog for all 13,000 is fantasy math, and I say that as the guy who did the addition.

What you can do with this. When the next rulemaking notice opens for comment, show up: that impaired-driving docket drew 18,367 public comments, one of the decade’s most-commented, and produced zero final rules.^[9] Pressure is the only input that moves this docket. Buy the finished rule instead of waiting for the pending ones, and check that your next car has pedestrian automatic emergency braking now, because the 2029 mandate is three model years away. Interlocks work today for convicted offenders; NHTSA estimates they could avert up to 837 deaths a year, no sensor breakthrough required.^[6] And say the quiet part to your representative: you cannot order 57 rules and staff 554 people to write them. NHTSA owes Congress a rulemaking status report twice a year, and the December 2024 edition is the most recent one it has published.^[4]
