Johnson County Courthouse — Iowa City
417 S Clinton St, Iowa City, (319) 356-6060. Traffic citations issued in Coralville, North Liberty, Iowa City, on I-80 or I-380 in Johnson County are filed at the Johnson County Clerk of District Court. There is no separate "traffic court" building. Most simple-misdemeanor traffic matters are handled by magistrates at the Johnson County Courthouse.
Who's writing the ticket
Citations issued to Coralville drivers come from several agencies:
- Coralville Police Department — city streets and Coralville stretches of major roads
- Iowa City Police Department — Iowa City limits
- Johnson County Sheriff — unincorporated Johnson County and county roads
- Iowa State Patrol — I-80, I-380, and US highways
- University of Iowa DPS — UI property
Regardless of which agency issued the citation, the case is filed at the Johnson County Courthouse in Iowa City — not at Coralville City Hall.

Your three options on a citation
| Option | What it means | License consequence |
|---|---|---|
| Pay the fine | Guilty plea entered, conviction on record | Counts as a moving violation |
| Contest in court | Trial before a magistrate or judge | If dismissed, no conviction |
| Request deferred | (Limited availability) Plea held, dismissed if you stay clean | No conviction if successful |
Option 1 — paying = pleading guilty
Paying the scheduled fine before the court date is an admission of guilt. The conviction goes on your driving record and is reported to your insurance and to the Iowa Department of Transportation. For most drivers with a clean record and a simple speeding ticket, this is the path of least resistance. For everyone else, read on.
Option 2 — contesting
You request a court date and appear (or have an attorney appear). You can challenge the basis for the stop, the accuracy of the radar or pace, the officer's observations, or argue for a reduced charge. Many simple traffic charges are resolved at first appearance through a plea bargain with the prosecutor — often a reduction to a non-moving violation (which doesn't go on the driving record).
Option 3 — deferred / driving school
Iowa allows a deferred judgment on some traffic offenses if the judge agrees. You're typically required to complete a defensive driving course and stay violation-free for a probationary period; the case is then dismissed. Not available for every offense or every defendant — judges look at your driving history.
Iowa scheduled fines
Iowa publishes a scheduled fine for routine traffic offenses — the amount printed on the citation is the same statewide for the same offense. Examples (current amounts can change):
| Violation | Scheduled fine |
|---|---|
| 1–5 mph over (interstate) | $20 |
| 6–10 mph over (interstate) | $40 |
| 11–15 mph over (interstate) | $80 |
| 16–20 mph over (interstate) | $90 |
| 21–25 mph over (interstate) | $100 |
| 1–5 mph over (non-interstate) | $30 |
| Failure to stop (stop sign / signal) | $195 |
| Failure to yield | $135 |
| Following too close | $135 |
| Improper lane change | $135 |
| Seat belt | $45 (+ surcharge) |
| No proof of insurance | $330 |
| Driving while suspended | $330+ |
Add Iowa criminal surcharge (15%) and court costs ($60+) to most fines. The bottom line on a "$80" ticket is often $150 or more.
Iowa license points — sort of
Iowa does not use a traditional points system like many other states. Instead, Iowa tracks moving violations and certain serious offenses directly:
- 3 moving violations in 12 months can trigger an Iowa DOT license review and possible suspension
- Certain serious offenses (reckless driving, racing, eluding) trigger automatic license action regardless of count
- Habitual offender — 3 major offenses (OWI, reckless, leaving scene, etc.) in 6 years = mandatory 2-year revocation under Iowa Code 321.555
Your auto insurance carrier maintains its own internal point system — and a single moving-violation conviction can raise rates 20–40% for three years.
Reckless driving — not just a ticket
Other moving offenses that are criminal rather than civil: eluding (321.279), drag racing (321.278), leaving the scene (321.263), driving while barred or while license is suspended (321.218, 321.561), OWI of course (321J.2). See Coralville OWI lawyer and criminal defense.
CDL drivers — far stricter rules
If you hold a commercial driver's license, traffic citations cost you more — even when driving your personal vehicle.
- Lower BAC threshold for OWI while operating a CMV: 0.04% (vs. 0.08% for regular drivers)
- "Masking" prohibited — CDL drivers cannot accept a deferred judgment or plea-bargain reduction that hides a moving violation. Federal regulation prohibits deferred adjudication for CDL holders.
- Serious traffic violations (15+ over, reckless, improper lane change with fatality, etc.) — 60-day disqualification on second conviction in 3 years; 120-day on third
- Major violations (OWI, leaving scene, drug felony with CMV, etc.) — 1-year CDL disqualification on first offense, lifetime on second
- Convictions in your personal vehicle still count against your CDL
If you hold a CDL, almost any traffic citation justifies a consultation with a lawyer before you pay or appear.
When to hire a traffic attorney
- You hold a CDL — almost always
- You've had 2+ moving violations in the last 12 months
- The charge is reckless driving, eluding, leaving the scene, or another criminal traffic offense
- The fine is $300+
- You're charged with driving while suspended, barred, or without insurance
- Your insurance is already high — even small rate increases compound
- The case involves an accident or injury
- You're a teenager or under 21 (under graduated licensing)
- You're a non-citizen (some convictions affect immigration status)
Typical fees
| Service | Typical fee |
|---|---|
| Simple speeding ticket (negotiate to non-moving) | $250–$500 flat |
| Multi-charge citation or CDL matter | $500–$750 |
| Reckless driving (misdemeanor) | $750–$2,000 |
| Driving while suspended / barred | $750–$2,500 |
| License reinstatement / habitual offender hearing | $1,500–$5,000 |
For routine citations, an attorney often resolves the case without your needing to appear. Whether it's worth the fee depends on what you'd save in insurance increases and what your license can tolerate.
Out-of-state drivers and the I-80 ticket
Iowa is a member of the Driver License Compact — most states share conviction data. Your Iowa I-80 speeding ticket will likely show up on your home state's record and your insurance. Ignoring an Iowa citation also triggers a hold on your driving privileges: pay it or contest it; don't let it lapse.
FAQ — Iowa traffic tickets
What happens if I just ignore my Iowa traffic ticket?
The court will enter a default conviction, your license can be suspended for non-appearance, and the case is reported to your insurance and (for out-of-state drivers) your home state. Costs add up fast.
Does Iowa use a points system?
Not in the traditional sense. Iowa tracks moving-violation convictions directly. Three moving violations in 12 months can trigger DOT review. Three major offenses in 6 years triggers habitual offender status — mandatory 2-year revocation.
Can I get a deferred judgment on a traffic ticket?
For many non-major violations, yes — at the magistrate's discretion. CDL holders cannot accept a deferred to "mask" a violation under federal regulation.
Will my insurance go up if I pay the ticket?
Paying = guilty plea = conviction reported. A moving-violation conviction typically raises auto insurance 20–40% for three years. Reckless driving and serious speeding cause larger increases.
Do I need to show up in court if I just pay the fine?
No. Paying the scheduled fine before the court date resolves the case (and enters a guilty plea). If you want to contest or seek a reduction, you must request a court date.
I'm a CDL driver. Should I hire a lawyer?
Almost always. Federal regulations prohibit CDL holders from using deferred judgments to mask violations, and CDL disqualification thresholds are lower than for regular drivers. A small attorney fee often protects a livelihood.
