The National Highway Traffic Safety Administration (NHTSA) report examined the costs of a single year of crashes that killed an estimated 36,500 people, injured 4.5 million, and damaged 23 million vehicles. The report found traffic crashes cost taxpayers $30 billion in 2019 and when quality-of-life valuations are factored in "the total value of societal harm from motor vehicle crashes in 2019 was nearly $1.4 trillion," the agency said.
