Out-of-State Travel Deaths Dropped 12%. Every Other Category Wishes It Could Keep Up.

Buried in NHTSA's November 2024 subcategory dump, between ejection rates and pedestrian counts, was a number that didn't belong: deaths during out-of-state travel fell 12% in the first half of 2024 compared to the same period in 2023. Nothing else came close. Not speed. Not booze. Not rollovers. Just driving on somebody else's road.

Pedestrian deaths fell 3%. Speeding crashes, 6%. Nighttime fatalities, 4%. Overall, 2024 closed at 39,254 dead, 3.8% below 2023's 40,901. A perfectly respectable body count reduction, as body count reductions go. But 12% is three times that pace. Something changed specifically about driving on roads you've never seen before, and it changed faster than almost anything else in American traffic safety.

Look at what else dropped hard. Ejected passengers: down 9%. Urban interstates: down 8%. Rollovers: down 6%. Roadway departures: down 5%. Not random categories. A checklist of exactly what lane-keeping assist, forward collision warning, and automatic emergency braking were built to prevent. Lane drift. Missed stops. Misjudged curves. The five fastest-declining subcategories all share one trait: they're failure modes of an inattentive driver on a road they don't know.

Which is either encouraging or deeply unsettling. ADAS appears to concentrate its lifesaving benefits where drivers are most distracted, and that's somebody else's state. Your Tuesday morning left turn onto the same four-lane you've taken since 2018? You've disabled lane departure warnings because they annoyed you. You know the curve tightens after the bridge. But on I-70 through Kansas at 11 p.m., four hours into a drive you've never made, that chirp saves your life.

Caveats are piling up in the hallway. "Out-of-state" in FARS means license state doesn't match crash state — New Jersey commuters crossing into Manhattan, families hauling to Yellowstone, same bucket. Post-pandemic remote work may have thinned the border-commuter subset. Cheaper flights may have pulled some long-haul drivers off the road entirely.^[1] And the 12% figure covers only the first half of 2024. It could revise. They always could.

Strip away what you can, and the signal persists. ADAS works best where you need it most. The 2024 fatality rate landed at 1.19 per 100 million VMT^[2]; the 2025 preliminary suggests 1.10.^[3] Real progress, genuinely lopsided. NHTSA doesn't publish in-state-vs-out-of-state rates separately, so we can't directly compare how much your familiar roads improved. But a 12% subcategory decline against a 3.8% overall decline is a spread wide enough to mean something. Unfamiliar roads got safer fast. Everything else got safer slowly.

Driving across state lines this summer? Activate every assist system your car has. Lane keeping. Adaptive cruise. Forward collision warning. Not a suggestion; it's an actuarial observation. These systems were built for the exact situation where your attention is worst and the road is least familiar. And if your vehicle predates them, the most important safety upgrade isn't a dashcam or a tire monitor. It's a newer car. The data just told you why.
