Inside, they are equipped with a better radio system and a computer that syncs with the deputy's desktop at the department.
They also come with an advanced dash cam and body cam system. The vehicles also have updated medical equipment.

"In total, it makes the deputies safer on the streets. It's better for citizens, it's more efficient, and overall improves public service," said Commander Tyson Pogue.
The department expects to replace another dozen units next year.
