A new national analysis from Bader Law reveals that December remains one of the most dangerous months on U.S. roads, with impaired driving contributing to a disproportionate share of crashes, injuries, and fatalities during the holiday season. The study draws on federal crash data, arrest records, trauma‑center toxicology reports, and multi‑year fatality trends to identify where and why December risk spikes.
Every hour, an impaired driver kills someone in the United States. More than 14,000 people die each year in impairment‑related crashes, and the CDC estimates the economic cost of drunk‑driving deaths alone reached $123.3 billion in 2020. Yet Bader Law’s analysis shows that official arrest numbers capture only a fraction of the problem: national survey data suggests 18.5 million Americans drive after drinking, 11.7 million drive after using marijuana, and 2.4 million drive under the influence of other illicit drugs.
Repeat offenders remain a major threat. Drivers with a prior impairment conviction are 4.1 times more likely to be involved in a fatal crash, and the average drunk driver has driven impaired 80 times before their first arrest.
States With the Highest Impaired‑Driving Fatalities
From 2023 fatal‑crash data, the states with the most drunk drivers involved in deadly collisions were:
- Texas – 6,121
- California – 5,564
- Florida – 5,027
- Georgia – 2,261
- North Carolina – 2,211
Georgia stands out: despite being only the eighth‑largest state, it ranks fourth in impaired‑driver fatalities — a pattern Bader Law attributes to rapid urbanization, congestion, and high‑speed corridors.
States with the fewest impaired‑driver fatalities include the District of Columbia (56), Alaska (87), Rhode Island (89), and Vermont (90 — all states with smaller populations and strong enforcement programs.
Arrest Patterns Don’t Match Fatality Trends
Between November 2023 and November 2025, the FBI recorded 1.39 million impaired‑driving arrests, with men accounting for 75% of all cases.
The top arrest states were:
- California – 189,743
- Texas – 119,917
- Pennsylvania – 66,379
- Ohio – 49,553
- Washington – 45,699
Notably, Florida, despite ranking third in impaired‑driving fatalities, does not appear in the top ten for arrests — a mismatch Bader Law says reflects differences in enforcement intensity, policing strategy, and resource allocation.
Georgia again shows a disparity: it ranks fourth in fatalities but only tenth in arrests, suggesting enforcement gaps relative to risk.
December: A High‑Risk Month for Every Age Group
In December 2024, 3,165 people died in U.S. crashes — far higher than the 2,675 deaths recorded in January 2025. Older adults (65–74+) accounted for 23% of December fatalities, largely due to physical vulnerability and slower reaction times.
But when isolating alcohol‑impaired drivers, the risk shifts dramatically toward younger adults:
- 28% of impaired drivers in fatal crashes were ages 21–24
- 26% were ages 25–34
- 23% were ages 35–44
During Christmas 2023 alone, drivers aged 25–34 accounted for 21 impaired‑driving deaths — more than any other age group.
Poly‑Drug Use Is Now a Leading Threat
A multi‑state trauma‑center study found that 54% of seriously injured drivers tested positive for alcohol and/or drugs. Among them:
- 25% tested positive for marijuana
- 22% for alcohol
- 10% for stimulants
- 9% for opioids
- 8% for sedatives
Poly‑drug impairment — any combination of substances — accounted for 44% of fatal‑crash toxicology cases, making it the single most dangerous impairment category.
Cannabis‑related impairment is rising sharply. Since Colorado legalized recreational marijuana, traffic deaths involving cannabis‑positive drivers increased 138%, and overall state traffic deaths rose 29%. In legalized states across the West, crash rates increased 6% compared with neighboring states.
Yet public perception lags behind reality: only 70% of drivers believe it’s dangerous to drive within an hour of using cannabis.
Fatigue: The Overlooked Impairment
Drowsy driving remains a major contributor to December crashes. According to the CDC:
- 1 in 25 adults has fallen asleep at the wheel
- Driving after 20+ hours awake mimics a BAC of 0.08
- Fatigue contributes to 21% of fatal crashes
AAA estimates drowsy driving causes 300,000+ crashes, 100,000 injuries, and up to 6,400 deaths annually.
Holiday Weekends Are the Deadliest Days of the Year
Christmas Eve and New Year’s Eve consistently rank among the most dangerous driving days in America. Bader Law’s analysis shows that alcohol, cannabis, prescription drugs, stimulants, sedatives, and fatigue all converge during December — creating a perfect storm of risk.
The firm notes that lowering the national BAC limit from 0.08 to 0.05 — a standard already adopted in Utah — could save an estimated 1,790 lives each year.
