Bexar County follows Texas Transportation Code rules for bicycles on roadways. Cyclists ride with traffic, use lights at night, and may use the full lane when the lane is too narrow to share. Few unincorporated roads have dedicated bike lanes.
Texas Transportation Code 551 governs bicycle operation across Bexar County. Cyclists are treated as vehicles, must ride with the flow of traffic, signal turns, and use a white front lamp and red rear reflector or lamp at night. Riders may take the full lane when the lane is too narrow to share safely or when avoiding hazards. Most unincorporated Bexar County roads are rural shoulders without striped bike lanes; San Antonio and other incorporated cities maintain their own bike network. The Bexar County Sheriff and Texas Department of Public Safety enforce traffic rules on county roads. Local advocacy partners with VIA on bike-on-bus integration.
Riding without required lights at night, against traffic, or violating helmet rules in cities that adopt them can result in traffic citations under Texas law.
