Driving without enough sleep can be just as dangerous as driving under the influence. Fatigue slows your reaction time, impairs focus, and clouds judgment—all of which are critical for safe driving. In fact, research shows that driving after sleeping only 3–5 hours in the past 24 hours can have effects comparable to driving under the influence (CDC, AAA Foundation for Traffic Safety).
Who’s Most at Risk
While anyone can experience drowsy driving, some groups face higher risk:
-
Young drivers (ages 16–25): They often get less sleep and have less driving experience.
-
Shift workers: Irregular or overnight schedules disrupt the body’s natural sleep rhythm.
-
Commercial and business travelers: Long hours behind the wheel increase fatigue risk.
-
People with untreated sleep disorders or chronic sleep deprivation: Conditions like sleep apnea can significantly impair alertness.
According to the National Highway Traffic Safety Administration (NHTSA), drowsy driving causes thousands of preventable crashes every year.
Recognize the Warning Signs
If you experience any of these symptoms, it’s time to pull over safely:
-
Frequent yawning or blinking
-
Trouble keeping your eyes open or your head up
-
Drifting out of your lane or hitting the rumble strip
-
Forgetting the last few miles driven
-
Missing signs, exits, or turns
Don’t try to “push through it.” Even short lapses in attention can be deadly. Pull over somewhere safe, rest, and recharge before getting back on the road.
Tips to Prevent Drowsy Driving
-
Get enough sleep: Aim for 7–9 hours a night to be your Best Slept Self® (National Sleep Foundation).
-
Avoid relying on caffeine: It’s a short-term fix that can wear off suddenly, leaving you even more tired.
-
Check your medications: Many prescription and over-the-counter drugs cause drowsiness (FDA).
-
Plan ahead: Schedule rest breaks or overnight stops on long trips.
-
Share driving duties: If you’re traveling with others, take turns behind the wheel.
-
Pull over safely: Never stop on a highway shoulder—find a rest area or a well-lit parking lot.
