Speed Limits and Right-of-Way Basics

Speed limits and right-of-way in San Tan Valley are governed primarily by Arizona state traffic law; local county roads may have posted limits set by Pinal County. Drivers must obey posted speed limits and state right-of-way rules; when signs or signals conflict with unwritten local expectations, the posted device controls.

  • Obey posted limits on local and county roads; where none are posted, refer to state statutory speed limits.[1]
  • Yield rules for intersections, pedestrian crosswalks and emergency vehicles follow Arizona statutes and are enforced by county or state officers.
When in doubt at an uncontrolled intersection, yield to the vehicle on your right.

Penalties & Enforcement

Enforcement in San Tan Valley is carried out by the Pinal County Sheriff, Arizona Department of Public Safety on state highways, and municipal or county traffic officers where applicable. Citations may result in fines, court appearances, administrative actions against a driver license, and other sanctions depending on the violation.

  • Fines and civil penalties: not specified on the cited statute page for local application; consult the cited statutes and county fee schedules for amounts.[1]
  • Escalation: statutes and county rules describe differing consequences for first, repeat, and continuing offences; specific escalation amounts or schedules are not specified on the single cited state statute page.[1]
  • Non-monetary sanctions: driver license suspension or revocation for DUI, orders to appear in court, probation, community service, and vehicle impoundment may apply under state law.[2]
  • Enforcer and complaints: traffic stops and collisions are handled by Pinal County Sheriff; administrative questions for motor vehicle licensing are handled by Arizona MVD.[3]
If you receive a traffic citation, note the deadline on the citation for payment or contesting in court.
