Westminster, CO Traffic Laws: Speed, Right-of-Way, DUI

Transportation Colorado 4 Minutes Read · published March 01, 2026 Flag of Colorado

Westminster, Colorado maintains local traffic regulations that work alongside state law to govern speed limits, right-of-way, impaired driving, and traffic calming measures on city streets. This guide summarizes where those rules are codified, who enforces them, how common violations are handled, and the practical steps residents can take to request calming treatments or appeal enforcement actions. It references the city code and police enforcement pages for official text and contact points so you can find the controlling ordinance or submit a complaint. Municipal code[1]

Speed limits

Speed limits within Westminster are set in the municipal traffic code and by official signage. Local limits on residential streets, collectors, and arterials are established by ordinance or by traffic engineering determinations; posted signs govern actual limits drivers must follow. For legal text and specific posted-speed authority, consult the municipal code and traffic engineering procedures. Enforcement & traffic safety[2]

Posted signs control the enforceable speed at any location.

Right-of-way rules

Right-of-way at intersections, crosswalks, and when entering roadways is regulated by the city traffic code consistent with state statutes. Drivers must yield as specified by signs, signals, and statutory rules; pedestrians in marked crosswalks generally have priority. The municipal code contains the local adoption and any modifications to state right-of-way rules.

DUI and impaired driving

Impaired driving enforcement in Westminster is implemented by the Westminster Police Department under Colorado law. Local officers investigate and charge impaired driving under state DUI statutes; municipal code references enforcement authority but often defers to state penalties for criminal DUI offenses. For criminal penalties and license sanctions, see the Colorado statutes and DMV resources linked in Help and Support / Resources.

DUI offenses are prosecuted under state law and may include arrest even if a local ordinance is silent on specific penalties.

Traffic calming and local engineering

Traffic calming requests, engineering studies, and installation of physical measures (speed cushions, curb extensions, signage) are handled by the city Public Works or Traffic Operations division. Residents can request traffic studies or calming treatments; project prioritization follows engineering criteria and available budget.

Traffic calming follows an engineering evaluation and community input process.

Penalties & Enforcement

The city's traffic code establishes violations and enforcement processes; where the municipal code defers to state law (for example, criminal DUI), state penalties apply. The municipal code pages and police enforcement pages are the controlling sources for citation authority, fine schedules where listed, and appeal routes. See local code[1]

  • Monetary fines: specific dollar amounts for many traffic infractions are not specified on the cited page; see the municipal code and the citation form for amounts and court costs.
  • Escalation: information on first, repeat, or continuing offense escalations is not specified on the cited page when the municipal code references state law for criminal matters.
  • Non-monetary sanctions: officers and courts may issue orders, require compliance measures, suspend privileges, or pursue court action; seizure or immobilization may occur under specific statutes or court orders.
  • Enforcer and reporting: Westminster Police Department handles traffic enforcement and complaints; traffic engineering (Public Works) handles signage and calming requests. [2]
  • Appeals and review: traffic tickets and administrative notices include appeal instructions and court dates; time limits for filing an appeal or requesting a hearing are shown on the citation or notice and in the municipal code or court rules—if not printed, the time limit is not specified on the cited page.
  • Defences and discretion: officers and courts may consider permits, emergency actions, or reasonable excuses; specific statutory defenses appear in state law for criminal offenses.
If a penalty amount or deadline is not printed on your citation, check the municipal code or contact the police records or municipal court immediately.
