Modoc County, CA Parking Rules: Snow Removal Parking Rules (2026)

Despite Modoc County's heavy mountain winters, its code does not contain a standalone snow-removal or seasonal winter-parking chapter that bans parking on county roads during storms (unlike some neighboring snow counties). The county's Title 10 traffic code regulates speed zones, through-highways, no-parking areas near emergency buildings, and abandoned vehicles, but has no November-to-May roadside parking ban. What the county can use during snow operations is its general no-parking authority: under Modoc County Code Chapter 10.12, the county road commissioner may designate and post no-parking areas on county highways and rights-of-way, and posted restrictions are enforceable. For vehicles that obstruct plowing or are left on the road, the California Vehicle Code provides removal authority - Section 22651 allows removal of vehicles obstructing the normal movement of traffic or snow-removal operations, and Section 22651(k) covers vehicles left standing 72 or more hours. The Modoc County Public Works / Roads Department conducts plowing and may post temporary no-parking or vehicle-removal signage during storms. Because the county code does not fix specific winter dates or fines, residents in snow-prone areas such as Alturas, Cedarville, Adin, and Cedarville should follow posted signs and clear roadways and driveway aprons ahead of plows; confirm current winter parking guidance directly with Public Works.
