Background Info

Speeding puts the driver and everyone else on the road in danger of a serious injury or a fatal crash. In 2021, approximately 2.50 million people were injured in motor vehicle crashes in the United States (U.S.) [1] During the same year, according to the National Highway Traffic Safety Administration (NHTSA), 12,330 people were killed in speeding related crashes in the U.S. [2].

Reportedly, per the National Safety Council (NSC) data in 2021, the proportion of speeding related crashes decreased as the age of the driver increased [3]. At the time of a fatal crash, male drivers were more likely to be engaged in speeding than their female counterparts across all age groups, with the most frequent being young male drivers in the range of 15-24 years [3].

Transitioning to Nevada data, in a report published by Zero Fatalities Nevada, for the years 2017-2021, there were 436 speeding related fatal crashes and 491 speeding related fatalities [4].
