How did Juneteenth reshape US road traffic in 2025? A full-week study of June 14–22 - bracketing the federal holiday on Thursday, June 19 - measured against a four-week per-day-of-week baseline, with a Texas city deep dive honoring the holiday's origins.

June 6, 2025 - a Friday. D-Day is not a federal holiday, so the national fleet barely moves: −2.1%, within normal weekday variance. But beneath that quiet aggregate lies a sharply structured signal a −24.3% collapse in Washington DC, an afternoon suppression, and a late-night surge.

A collision spike, a vanishing fleet, and the one segment that tells the truth - across 263,877 Orlando rides, 2025 vs 2026.

Across 739,950 rides in two matched five-month windows, the Las Vegas collision rate rose +231% (139 → 460 per million), yet hard braking improved 16% and harsh acceleration fell 71%. The spike is not city-wide: it concentrates in North Las Vegas and the first two months of 2026.

Race Day Sunday, May 25, 2025. The Indianapolis 500 drew an estimated 275,000 spectators to the Indianapolis Motor Speedway, yet Nexar fleet data captured a striking paradox: a city-wide traffic suppression, not a surge. This is what 275,000 people in one place looks like on the road network around them.

The next Blue Moon rises on Sunday, May 31, 2026, only the third since 2021. Drawing on Nexar's May 2025 fleet baseline and peer-reviewed traffic-safety literature, this study models a "watch-for" narrative, a ceiling scenario consistent with external research, not a verified forecast.

What happens to professional driving networks when America stops working? A full-week study of May 19-26, 2025, bracketing the federal holiday on Monday, May 26, measured against a four-week same-day-of-week baseline.

What happens to professional driving networks when Americans commute by bicycle? A full-season study of May 15, 2025, the US national Bike to Work Day.

Nexar telematics data shows a +79.7% rise in IMU-detected collision rate year over year, coexisting with an all-time record low in NYC traffic fatalities. This study traces the structural causes (Congestion Pricing, fleet composition, a Feb 2026 penalty law) and finds the gap closing in April.

Conventional wisdom says the days after New Year's Eve should be dangerous. The data tells a different story. January 2025 flips the script: the first week of the year was actually safer than average, while the middle of the month emerged as the real danger zone.

Analysis of 910,363 rides during the New Year period reveals critical safety patterns around the midnight transition. Between 19:00-20:00, danger peaks at 169% as roads fill with last-minute travel; after midnight, from 00:00-04:00, danger drops to just 23-48%. High risk doesn't follow the clock. It follows human behavior.

It's clear to anyone who knows the importance of Thanksgiving across the US that it impacts the regular life of all Americans. But how significantly, and in what ways, does driving activity during Thanksgiving week deviate from a regular week?
