Summary

On unincorporated Williamson County roads, parking follows the Texas Transportation Code, which bars stopping in an intersection, on a crosswalk, on a bridge, or where an official sign prohibits it.

City-specific rules exist: Round Rock, and Cedar Park have their own street parking limits rules that differ from Williamson County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

An operator may not stop, stand, or park a vehicle: (1) on the roadway side of a vehicle stopped or parked at the edge or curb of a street; (2) on a sidewalk; (3) in an intersection; (4) on a crosswalk; (5) between a safety zone and the adjacent curb or within 30 feet of a place on the curb immediately opposite the ends of a safety zone, unless the governing body of a municipality designates a different length by signs or markings; (6) alongside or opposite a street excavation or obstruction if stopping, standing, or parking the vehicle would obstruct traffic; (7) on a bridge or other elevated structure on a highway or in a highway tunnel; (8) on a railroad track; or (9) where an official sign prohibits stopping.

Full Breakdown

Williamson County has no municipal-style street-parking ordinance. On county-maintained roads the Texas Transportation Code controls: a driver may not stop, stand, or park in an intersection, on a sidewalk or crosswalk, on a bridge or other elevated structure, or where an official sign prohibits stopping. A vehicle also may not block traffic alongside a street excavation. The Commissioners Court can post specific no-parking zones, but most rural shoulders carry no restriction.

Violations & Fines

Illegal stopping or parking on a county road under Transportation Code 545.302 is a Class C misdemeanor, and law enforcement may have the vehicle towed.
