According to the National Highway Traffic Safety Administration (NHTSA), 37,133 people lost their lives in accidents on U.S. roadways in 2017 1. That means an average of 101 people died each day in motor vehicle crashes, equating to roughly one fatality every 15 minutes. The FAST Act has funded programs to ensure safety on our Nation's roads. These include grants to improve physical roadway infrastructure; grant programs to reduce crashes, injuries, and fatalities involving large trucks and buses; grant programs to incentivize States to adopt laws and regulations to improve highway safety; and grants to assist State enforcement of vehicle and driver safety measures. This book discusses traffic safety issues.
