Speed limits and right-of-way basics

The City enforces speed limits and right-of-way rules through local traffic regulations and by applying the California Vehicle Code on city streets. Local speed limits and traffic controls are established under the City municipal code and traffic resolutions; see the official municipal code for ordinance language and adopted rules Simi Valley Municipal Code[1].

Local speed limits often reflect engineering studies and council actions.

Penalties & Enforcement

Enforcement is handled primarily by the Simi Valley Police Department for moving violations and by city departments for parking and local ordinance violations. Exact fine amounts for many moving and municipal violations are not always listed on the city pages and may follow state schedules or fee resolutions; if a specific amount or schedule is not shown on the cited page it is noted below.

  • Fines: specific dollar amounts for many traffic violations are not specified on the cited municipal code page; many fines are set by state statute or by separate fee schedule.[1]
  • DUI criminal fines: amounts vary by offense level and are not fully specified on the local pages; see state resources for statutory ranges.[3]
  • License actions: administrative license suspension and the right to request a DMV hearing are governed by the California DMV; you typically have 10 days to request an administrative hearing after an arrest for impaired driving per DMV instructions.[3]
  • Non-monetary sanctions: common sanctions include license suspension, probation, mandatory programs, vehicle impound or release conditions, and court-ordered restrictions; local procedures for impound or release are handled by Simi Valley Police Department or towing administrators and may require payment of fees not specified on the cited city pages.[2]
