San Antonio's Bike Plan and SAMC Chapter 19 govern bicycle operation on city streets, requiring motorists to provide three feet of passing distance, while the citywide bike network expands protected lanes, neighborhood greenways, and bayou trails.
The San Antonio Bike Plan, adopted by City Council and updated periodically, sets a multi-decade roadmap for protected bike lanes, neighborhood bikeways, and shared-use paths along the San Antonio River and creeks. SAMC Chapter 19 governs vehicle and bicycle operation, requiring motorists to maintain at least three feet of passing distance from cyclists, with six feet for trucks and commercial vehicles under the SA Vulnerable Road User Ordinance. Cyclists must follow traffic signals, ride with traffic, use lights at night, and yield to pedestrians on shared trails. Sidewalk riding is prohibited in the central business district. The TCI Department coordinates with VIA, TxDOT, and Bexar County on regional connections and federal funding.
Motorist three-foot passing violations carry fines up to 500 dollars under SAMC Chapter 19. Blocking a bike lane is around 200 dollars plus tow. Cyclist signal violations and prohibited downtown sidewalk riding face fines up to 200 dollars.
