Inside a Central Florida Sheriff’s Office Bi-Fuel Propane Fleet Program

348 bi-fuel patrol vehicles. Eight fueling locations. More than a decade of experience.

Since 2015, the Polk County Sheriff’s Office in Central Florida has used propane to help

manage fuel costs across a county spanning 2,010 square miles.

Its bi-fuel vehicles allow officers to switch between propane and gasoline, extending driving range while supporting reliable patrol operations.

Building the program took more than vehicle conversions. The agency evaluated safety, tested equipment, developed fueling infrastructure, and learned the importance of dependable technical support.
