Transportation Texas 3 Minutes Read ยท published February 05, 2026 Flag of Texas

San Antonio, Texas carriers must follow specific municipal rules and the official truck route map to avoid fines and enforcement. This guide explains where trucks are authorized, common route restrictions, permit basics, and how enforcement works under San Antonio city ordinances. It summarizes official sources, complaint and permit contacts, and practical steps carriers should take before routing heavy vehicles through the city.

Authorized Truck Routes & Restrictions

The City publishes an official truck route map and defines restricted streets where heavy or commercial vehicles are limited or prohibited. Always consult the City Code and the published route map before planning movements within San Antonio. See the City Code and route map for formal descriptions and limits: City Code - Code of Ordinances[1].

  • Designated truck routes require through trucks to remain on those streets unless making local deliveries.
  • Local restrictions may prohibit trucks on residential streets, low-clearance bridges, or weight-limited structures.
  • Special permits may be required for oversize or overweight loads or nonstandard routing.
Always review the official map before scheduling routes.

Routing, Signs, and Physical Restrictions

Truck route signage and physical restrictions (height/weight limits, bridge restrictions) are installed and maintained by City departments. Where posted limits conflict with a carrier's plan, carriers must follow posted signs and obtain necessary permits or choose alternate routes.

  • Bridge and structure weight limits govern allowed vehicle gross weight on specific spans.
  • Height and clearance signs apply to over-height loads; permits or escorts may be required.
  • Road work or temporary restrictions may create short-term route changes; check project notices.
