Florida law enforcement fleet sees significant fuel savings and reduces their carbon footprint with Derive’s software upgrades.

On average, police vehicles idle up to 65% in a 12-hour shift.
Port St. Lucie’s fleet exceeded this, idling 76% in each shift. Consequently, the department’s unnecessary fuel usage during idle was higher than normal. With this problem in mind, their Police Chief John Bolduc approached Derive with the following goals: Gain significant fuel cost savings by reducing idle fuel consumption without impacting the fleet’s performance, and Maintain their strict emission standards.


Port St. Lucie started with a pilot to test the software upgrades.

Derive installed its technology in a sample set of the fleet that included sedans, SUVs and a K-9 unit. As part of the validation Derive established a baseline, then used that data to create a refined solution.


After two months, Port St. Lucie’s PD fleet saw a meaningful reduction in the amount of fuel consumption.
