Car accidents pose significant risks, with around 5.25 million occurring annually in the U.S. alone, resulting in approximately 40,000 deaths. Key causes include distracted driving, bad weather, drunk driving, fatigue, and speeding, with spikes in accidents during certain hours, particularly in the evening and under the influence of alcohol. Preventative measures, such as wearing seatbelts and adhering to traffic rules, along with increased awareness, are essential to reduce the growing number of accidents.
