Yolo County was one of the original counties of California, created in 1850 at the time of statehood.

The county is governed by a board of five district supervisors as well as the governments of its four incorporated cities: Davis, West Sacramento, Winters, and Woodland.

Addressing in Yolo County is based on a system of numbered county roads. The numbering system works in the following way:
North–South roads have numbers from 41 to 117 and increase from west to east. East–West roads have numbers from 1 to 38A, and then from 151 to 161, and increase from north to south. Each integer road number is generally 1 mile (2 km) apart, with letters occasionally designating roads less than 1 mile (2 km) apart. County roads entering urban areas generally become named roads once they cross a city boundary. Some examples include County Road 101 in Woodland being renamed Pioneer Ave. and County Road 102 (also known as County Route E8) in Davis being named Pole Line Road.

Yolobus (Yolo County Transportation District) runs buses throughout Yolo County and into Sacramento, and Sacramento International Airport. The University of California, Davis and the city of Davis jointly run Unitrans, a combination local city bus and campus shuttle. Fairfield Suisun Transit Line 30 also stops in Davis on its runs between Fairfield (Solano County) and Sacramento. Amtrak has a station in Davis.

The Port of Sacramento, now known as the Port of West Sacramento, is an inland port in West Sacramento, California, in the Sacramento metropolitan area. It is northeast of San Francisco, and is centered in the California Central Valley, one of the richest agricultural regions in the world.
