This page explains how Ohio classifies traffic offenses, why most traffic tickets are criminal cases (usually minor misdemeanors), what the prosecution has to prove, and what "strict liability" means. It also covers the main exception: parking tickets that a city has made civil.
Ohio does not have a general category of civil traffic "infractions." Ordinary moving violations are criminal offenses, usually at the lowest level, the minor misdemeanor.
Ohio's offense classes include misdemeanors of the first through fourth degree and minor misdemeanors. R.C. 2901.02(A).
An unclassified offense is a minor misdemeanor if the only penalty is a fine of up to $150 (for offenses on or after January 1, 2004), community service, or a financial sanction other than a fine. R.C. 2901.02(G).
Example: speeding is a minor misdemeanor in the ordinary case, but becomes a fourth- or third-degree misdemeanor with prior speeding convictions within one year. R.C. 4511.21(P)(1).
The ticket is a criminal complaint. Traf.R. 3(A); Crim.R. 3(B). Where the Traffic Rules are silent, the Criminal Rules apply. Traf.R. 20.
A conviction is sent to the Bureau of Motor Vehicles and becomes part of your driving record. The judge must tell you this before you plead. Traf.R. 8(D)(5).
A city or other local authority may pass an ordinance making parking violations civil. If it does, the violation is "not ... a criminal offense for any purpose," it is handled under R.C. Chapter 4521, and you cannot be arrested for it. R.C. 4521.02(A); R.C. 4521.01. The local authority must set a deadline for answering the parking ticket. Check the ticket and the local rules for that deadline.
"Every person accused of an offense is presumed innocent until proven guilty beyond a reasonable doubt," and the prosecution has the burden of proof. R.C. 2901.05(A). The officer's ticket is an accusation, not a finding of guilt.
What you plead matters:
Not guilty: the prosecution must prove its case at trial.
No contest: not an admission of guilt, but an admission that the facts in the complaint are true, and the court then proceeds to sentencing. Traf.R. 10(B)(2), (3).
Guilty: a complete admission of guilt. Traf.R. 10(B)(1).
Paying the ticket by mail or at the clerk's office under R.C. 2935.26(C) counts as a guilty plea and waiver of trial. R.C. 2935.26(C).
No conduct is a criminal offense against the state unless the Revised Code defines it as one. R.C. 2901.03(A). Cities and villages also have traffic ordinances, and violations of those are also traffic cases. Traf.R. 2(A).
Generally, a person is guilty only if (1) the conduct includes a voluntary act, or a failure to do something the person was capable of doing, and (2) the person had the mental state the law requires for each element where one is specified. R.C. 2901.21(A).
Strict liability means guilt does not depend on what you knew or intended. If the law defining an offense names no mental state and plainly shows the legislature meant strict liability, no mental state is required. R.C. 2901.21(B).
For many crimes, if the law is silent about a mental state and does not plainly impose strict liability, the prosecution must prove you acted recklessly. R.C. 2901.21(C)(1). But that recklessness default does not apply to offenses in Title 45 of the Revised Code, which is the motor vehicle title. R.C. 2901.21(C)(2).
What this means for you: do not assume the prosecution must prove you were reckless just because the traffic statute does not mention a mental state. Whether a particular traffic law requires any mental state depends on that law's wording and on court decisions about it. Read the statute or ordinance listed on your ticket.
