Miami Traffic Laws: Speed, Right-of-Way, DUI

Transportation Florida 4 Minutes Read · published February 08, 2026 Flag of Florida

Miami, Florida drivers must follow a mix of city ordinances and state traffic laws that govern speed limits, right-of-way, and driving under the influence (DUI). This guide explains which municipal and state authorities enforce those rules inside the City of Miami, outlines typical penalties and appeal paths, and gives practical steps to report, pay, or contest citations. It cites official municipal code and police sources so you can verify sections and forms before acting. For legal advice in a specific case, consult a licensed attorney.

Speed Limits & Road Types

Posted speed limits in Miami are enforced where signs are present; unposted local streets may follow city code or state default limits. Check the City of Miami Code of Ordinances for local speed and traffic-control provisions via the municipal code portal City of Miami Code of Ordinances[1]. Where the municipal code is silent, state traffic statutes and Florida Department of Transportation rules may apply.

Always follow posted signs and temporary work-zone limits.

Right-of-Way Rules

Right-of-way at intersections, pedestrian crossings, and when merging generally follows the city code provisions and state traffic law; the municipal code provides local rules and enforcement authority. When in doubt at an intersection, yield to the vehicle or pedestrian already in the intersection or as directed by traffic-control devices and officers.

Pedestrians in marked crosswalks have priority; failing to yield can lead to citation.

Driving Under the Influence (DUI)

DUI in Miami is prosecuted under Florida law; the state statute defines prohibited conduct, per se blood alcohol concentrations, and criminal penalties. For statutory language on DUI offenses and penalties, see the Florida statute text for 316.193 online Florida Statute 316.193[3]. For local enforcement and reporting within the City of Miami, contact the Miami Police Department Traffic Unit Miami Police Department[2].

DUI penalties increase with prior convictions and high blood-alcohol readings.

Penalties & Enforcement

Enforcement is primarily carried out by the City of Miami Police Department and municipal code enforcement officers; criminal DUI cases are prosecuted under state law by the appropriate state or county prosecutor. The penalties vary by violation type and by whether the offense is municipal, civil, or criminal.
