Drowsy driving isn't something people aim to do behind the wheel. Most people get into their vehicles feeling perhaps a little tired or like they didn't get enough sleep. They don't think that this could lead to an accident, but it can. Nodding off even for a few seconds is enough time to cause a serious collision.
A 2005 poll from the National Sleep Foundation reported that around 60 percent of adult drivers had admitted to getting behind the wheel when feeling drowsy. Over a third had actually drifted off to sleep. Maybe more unexpected is that around 4 percent of those people were either in accidents or nearly in accidents because of how tired they were.
