The Auto Theft Prevention Act aims to provide financial support to state and local law enforcement agencies to help them tackle the issues of auto theft and the trafficking of stolen vehicles. The main goal is to reduce the incidence of these crimes and improve public safety. The Act establishes a grant program that allocates federal funding to state and local law enforcement agencies specifically for combating auto theft. States wishing to receive these grants must apply and demonstrate their need for assistance, including providing evidence of past efforts to reduce auto theft.
