Every year, road traffic crashes kill 1.35 million people worldwide, a number that is equivalent to the population of Maine. In 2019, 44 responders—18 law enforcement officers and 26 other responders, including fire, EMS, mobile mechanics, and tow and recovery personnel—died after being struck by a vehicle in the United States. On average, another 20,000 first responders are injured in the United States annually while responding to traffic incidents. At risk are not only the lives of the drivers and passengers involved but also the welfare of surrounding motorists and bystanders, the safety of police officers and other responders, and even the health of the economy.
