In 2016, the National Safety Council estimated that roughly 40,000 people were killed in motor vehicle accidents across the country. According to an insurance industry news source, this represents a 6% increase in fatalities over the previous year and reflects the highest number of deaths since 2007. The National Highway Traffic Safety Administration reported similar numbers, with an 8% increase in traffic deaths year-over-year.
In fact, since 2007, the number of traffic deaths has dropped dramatically. It was not until 2014 that the rate of traffic deaths started to slowly increase. However, since 2014, there has been a 16% increase in the number of traffic deaths.
Those who conducted the study point to several non-problematic factors that contributed to the sharp increase, including reasonable gasoline prices and a healthy economy. However, the researchers note that even taking these factors into account, the year-over-year total increase in miles traveled was only a 3% increase. This suggests that other factors are also in play.
