December is the festive heart of the year — it’s also National Impaired Driving Prevention Month. This is a time when social gatherings, end-of-year celebrations, and holiday parties drive a surge of impaired drivers onto U.S. roads.
Seasonal traffic enforcement campaigns and public safety messaging are in full swing. There’s never been a better moment to understand the cold, hard facts about impaired driving.
Learn why this issue touches everyone who gets behind the wheel.
The Numbers Behind the Headlines
Driving while impaired remains a deadly reality. In 2023, more than 12,400 people died in alcohol-impaired motor vehicle crashes. This accounted for nearly one-third of all U.S. traffic fatalities.
That equates to about one death every 40-45 minutes and underscores just how severe the problem is nationwide. The holiday season amplifies these risks. December has some of the highest drunk driving death totals of the year. This month sees more than a thousand fatalities alone in recent years.
These are more than unfortunate “accidents.” They are preventable deaths tied directly to choices made before anyone ever sets foot in a car.
The Numbers Behind the Headlines
While alcohol gets the most attention, impairment isn’t limited to booze. Drug-impaired driving, including cannabis and prescription medications that affect reaction time and judgment, is a growing factor. A study found that roughly 25% of seriously injured or killed drivers had active THC in their system.
Driving under the influence is not limited to alcohol impaired drivers. Many prescription sedatives, opioids, and even some over-the-counter medications can degrade driving ability without users realizing it. Legal use is not always indicative of being safe for driving.
Practical tip
If a medication label warns against operating machinery, don’t drive.
Who’s Really at Risk
Impaired driving fatalities extend across age groups, though certain demographics are more represented. Young adults — especially those ages 21–34 — consistently show higher involvement in alcohol-impaired fatal crashes.
Middle-aged drivers and repeat offenders also play a role, and the impact reaches far beyond the impaired driver. Passengers, pedestrians, cyclists, and occupants of other vehicles make up a significant share of victims. This issue is far from a “personal choice” with isolated consequences.
Make This December Different
Most people already know impaired driving is dangerous. The gap lies in turning that knowledge into action. Simple steps can make a life-saving difference: designate a sober driver, plan your ride home before the party starts, or use ride-sharing and local safe-ride programs. NHTSA
During December, law enforcement agencies often provide enhanced patrols to deter driving under the influence of drugs or alcohol. Many communities also offer free or discounted rides home. Make sure to plan ahead and take advantage of these programs.
Instead of a vague intent to “be careful,” make a specific transportation plan before your next holiday gathering. This is one of the few decisions that can truly change the outcome of your night.
