As daylight saving time kicks off, the New York State Partnership Against Drowsy Driving is emphasizing the danger of being tired behind the wheel.
Officials say being fatigued can cause a whole lot of problems for people on the road, including slowing their reaction time and impairing their vision.
They say it can increase the odds of crashes, injuries and fatalities.
One study even showed being awake for 24 hours straight left people more impaired than if they were over the legal alcohol limit.
Authorities recommend drivers pull over and rest if they feel sleepy.
The National Highway Traffic Safety Administration estimates there are at least 100,000 drowsy-driving-related crashes in the U.S. ever year.
