The Idaho State Police has saved money since hiring three employees to upfit police vehicles with radios, cameras, and prisoner transport systems in 2018. Each car — Dodge Chargers — take about 50 hours of work before they’re ready for service, and the program has saved the agency $100,000 over using outside shops, Idaho News reported.

Cars that reach 110,000 miles or 10 years are replaced, and some parts are then reused on new vehicles.
