Who Has Authority Over Vehicle Violations? A Quick Guide

Introduction

Traffic violations are enforced and adjudicated by a mix of law enforcement, prosecutors, and courts. Authority is shared and varies by jurisdiction, so the exact process can look different from place to place.

Enforcement authorities

Police, sheriff, and highway patrol officers are typically the first to observe violations and issue tickets. Local, county, and state agencies may all have enforcement roles, depending on the road type and the law being enforced.

Police, sheriff, and other enforcers

• Issue citations on the spot for observed violations.
• Enforce state and local traffic laws.
• May also perform roadside checks for impaired driving, registration, and insurance compliance.

Prosecutors and the courts

• Some violations are handled as civil infractions in a traffic or municipal court.
• In more serious cases, or for offenses like DUI, reckless driving, or driving with a suspended license, prosecutors decide whether to file charges.
• Courts or administrative agencies determine guilt and impose penalties.

Administrative actions and license penalties

• Many jurisdictions give a transportation department or DMV the power to suspend or revoke licenses, impose fines, and assign driving points.
• License actions may be issued administratively, separate from a criminal case.

Jurisdictional variations

• Countries and states differ in terminology and procedures.
• Some places use civil administrative hearings, others use traditional criminal courts.
• Penalties can include fines, points on a license, mandatory driving courses, or license suspensions.

What to do if you receive a ticket

• Read the ticket carefully for deadlines and instructions.
• Consider requesting a hearing or contesting the ticket if you believe it is inaccurate.
• Seek general information from the relevant DMV or court website about timelines and options.
• If needed, consult a qualified attorney for jurisdiction-specific guidance.

Key takeaways

• Authority over vehicle violations is shared among police enforcers, prosecutors, and courts.
• Administrative agencies (like the DMV) often handle license penalties.
• Processes and terminology vary by jurisdiction, so check local rules.
