Iowa speeding ticket fines and penalties start at a $30 base fine for 1 to 5 mph over the limit and climb from there, with every ticket carrying a 15% state surcharge and at least $55 in court costs on top. Drive 25 mph or more above any posted limit and the Department of Transportation will suspend your license for 60 days to a full year, no matter how clean your record was before.
What a Speeding Ticket Actually Costs
Iowa uses a tiered base fine set by Iowa Code 805.8A:1Iowa Legislature. Iowa Code 805.8A – Motor Vehicle and Transportation Scheduled Violations
- 1 to 5 mph over: $30
- 6 to 10 mph over: $55
- 11 to 15 mph over: $105
- 16 to 20 mph over: $120
- 21+ mph over: $135, plus $5 for every mph above 20 over the limit
That figure is only the starting point. A 15% crime services surcharge is added to every speeding fine,2Iowa Legislature. Iowa Code 911.1 – Crime Services Surcharge and court costs of $55 apply to scheduled violations whether you appear in court or not, rising to $60 if the case is filed as a simple misdemeanor.3Iowa Legislature. Iowa Code 602.8106 – Collection of Fees in Criminal Cases
Two examples show how quickly the total grows. Get caught at 12 mph over, and the $105 base fine becomes roughly $176 once the $15.75 surcharge and $55 in court costs are added. At 25 mph over, the base is $160 ($135 plus $25 for the five mph above 20 over), the surcharge is $24, court costs are $55 or $60, and you’re looking at close to $240 before any suspension consequences kick in.
When Speeding Costs You Your License
Iowa does not run a point system. The Department of Transportation tracks every moving violation on your record and imposes consequences based on volume or on the severity of a single offense.
Three Tickets in 12 Months
Three or more moving violations within any 12-month window make you a habitual violator, and the DOT will suspend your license.4Iowa Department of Transportation. Suspension for Habitual Violators and Serious Violation Suspension length climbs with each additional violation:5Iowa Legislature. Iowa Administrative Code 761-615.6 – Suspension for Habitual Violators
- 3 violations: 90 days
- 4 violations: 120 days
- 5 violations: 150 days
- 6 violations: 180 days
- 7 or more: 1 year
Out-of-state tickets count. A citation picked up on a road trip still lands on your Iowa record.
25 mph or More Over the Limit
A single conviction for driving 25 mph or more above any posted limit is a serious violation and carries a mandatory suspension. The minimums:6Iowa Legislature. Iowa Administrative Code 761-615.10 – Suspension for a Serious Violation
- 25 mph over: 60 days
- 30 mph over: 90 days
- 35 mph over: 140 days
- 40 mph over: 190 days
- 45 mph over: 290 days
- 49+ mph over: 1 year
A hearing officer can reduce these periods for mitigating circumstances, but that isn’t something to plan around. If your violation is between 25 and 29 mph over, the DOT may let you attend an eight-hour driver improvement course in place of serving the full suspension. Completing it puts you on a one-year probation rather than clearing your record.7Iowa Department of Transportation. Driver Improvement Program
Where Fines Double or Jump
Work Zones
Fines for any moving violation double in a road work zone, whether or not workers are actually present. The zone begins at the first “Road Work Ahead” sign and continues through the sign marking its end. A $55 base fine for 8 mph over becomes $110 before the surcharge and court costs, and a work-zone moving violation can reach a maximum fine of $1,000.
Passing a Stopped School Bus
Passing a school bus with its signal arm extended is one of Iowa’s most expensive traffic offenses. A first offense carries a fine between $345 and $930, up to 30 days in jail, or both. A second offense is a serious misdemeanor with steeper penalties, and the DOT can require a driver improvement course and suspend your license.8Iowa Legislature. Iowa Code 321.372 – School Bus Violations
Move Over or Slow Down
Approaching a stationary emergency vehicle, tow truck, highway maintenance vehicle, utility vehicle, or any car with its hazard lights flashing, you must change lanes away from it or slow to below the posted limit. The base fine is $135 plus surcharges and court costs.9Iowa Legislature. Iowa Code 321.323A – Approaching Certain Stationary Vehicles Cause a crash while violating this law and the consequences escalate sharply: a 90-day suspension for property damage, 180 days plus a $500 fine for bodily injury, or a one-year suspension plus a $1,000 fine if someone dies.10Iowa Department of Transportation. Move Over Or Slow Down
The Posted Limit Isn’t Always the Legal Limit
A speed limit sign is a ceiling. Iowa Code 321.288 requires you to slow to a “reasonable and proper” speed whenever conditions call for it, including near pedestrians or animals on the road, at intersections and sharp curves, when approaching an emergency vehicle with lights or siren, near slow-moving vehicles marked by the orange reflective triangle, and in work zones.11Iowa Legislature. Iowa Code 321.288 – Control of Vehicle, Reduced Speed An officer can cite you for driving at the posted limit if the conditions made that speed unreasonable. You don’t have to exceed the number on the sign to get a ticket under this statute.
One boundary worth knowing: the interstate system is off-limits to any vehicle that cannot reach and maintain 40 mph.12Iowa Legislature. Iowa Code 321.285 – Speed Restrictions Farm equipment, mopeds, and other slow vehicles must take alternative routes.
What to Do After You Get the Ticket
The clock starts the moment you’re cited. You generally have about 15 days to enter a plea or pay the fine. Ignore the ticket, and your license is suspended once the fine goes 75 days past due.13Iowa Judicial Branch. Traffic Citations – FAQ
Three options are open to you. Pay the scheduled fine, which counts as a guilty plea and lands the conviction on your record. Plead not guilty and request a hearing, which sends the case to trial where the officer must appear and the state must prove you were speeding. Or plead guilty and request a hearing to argue for a reduced penalty. Radar and lidar cases are usually straightforward for the prosecution, though calibration records or unclear signage sometimes create an opening.
Do not assume the driver improvement course wipes the slate. Your record will show convictions, accidents, and suspensions from at least the past five years no matter what courses you take.7Iowa Department of Transportation. Driver Improvement Program The course can help you avoid a suspension in certain circumstances, but the conviction itself stays.
