The question in the title is the one people actually type, and it does not have one answer. What it has is four inputs, and every one of them is either printed on your citation or published by your state. This post is about finding them.
Before any of it: the deadline on your citation is the only date that matters right now. In most states paying the amount printed on it is a plea of guilty that closes the case, so the deadline is not just when the money is due — it is when every other option stops being available. Nothing below is worth reading if the date passes while you read it.
First, work out what is actually at stake
Most people answer this question by looking at the amount on the ticket. That is the smaller half of the decision in most states.
A conviction for a moving violation does three things. It takes the fine. It puts whatever points your state assigns on your driving record. And it becomes visible to your insurer at the next renewal that falls inside its lookback period, which is set by the insurer rather than by the state.
The fine calculator on this site exists to put those together, because the second and third are the ones people do not see coming. For a lot of drivers the three-year figure is several times the number on the citation. For a driver in one of the eleven states that assess no points for speeding at all, it can be close to the citation and nothing more.
That spread is the first input, and it is why there is no general answer. The same ticket is a minor expense for one driver and a serious one for another, in a way that has very little to do with how fast either of them was going.
Second, find out what your state lets you do
“Contesting” covers several quite different procedures, and which ones exist depends on the state and often on the court.
Pleading not guilty converts the citation into a case. You enter the plea by the deadline, the court sets a hearing, and the burden is on the prosecution. In most states that means appearing in person, and it means the citing officer is expected to appear too.
Trial by written declaration is available in a handful of states and is genuinely different: the case is decided on written statements from both sides, with no appearance by anybody. Where it exists it removes most of the cost of contesting, which changes the arithmetic considerably.
Mitigation is not contesting at all. It accepts the violation and asks the court to reduce what follows — a smaller amount, time to pay, or in some states a deferral that dismisses the citation if you stay clean for a stated period. A deferral is often the most valuable thing on the menu, because a dismissed citation is not a conviction and there is nothing for an insurer to see.
Traffic school is the fourth route, and in states that allow it, it is the one most first-time drivers are actually looking for. It is a large enough subject to have its own guide, and the important thing here is that electing it usually has to happen before you pay, for the same reason as everything else on this list.
Which of these your state offers is not something to guess at. The result panel in the calculator links straight to your state’s own DMV and court pages, and those are the pages that settle it.
Third, look at what is specific to your citation
Three facts on the paperwork change the answer more than anything else.
The speed. Every state’s penalty steps up with the margin over the limit, and in some states it steps into a different category entirely. Fourteen states in our dataset name a speed at which speeding stops being a traffic infraction and becomes a criminal charge on a first offence — the reckless driving page lists them with the statute for each. If your speed is above your state’s line, this is not the decision you think you are making, and paying the citation is generally not one of the options anyway.
Where it happened. A signed construction or school zone carries an enhanced penalty in nearly every state, and the enhancement usually attaches to the zone rather than to whether anybody was working. That is covered on the work zone page.
What you drive for a living. A commercial licence changes everything about this calculation. Convictions are recorded differently, masking is generally prohibited outright, and the threshold at which a licence is at risk is lower. A driver in that position is not weighing a fine against an afternoon in court.
Fourth, be honest about the process
Contesting costs time. An appearance means a day, or at least a morning, and sometimes two if the matter is continued. That is a real cost and it belongs in the comparison — for a small fine in a no-points state it can easily exceed what is being disputed.
It is also worth being clear about what a contested hearing turns on. Most speeding cases are decided on the evidence of the measurement and the officer’s account of it, and the questions that matter are mundane: whether the equipment was calibrated and when, whether the officer can identify the vehicle, whether the posted limit was where it was said to be. These are not gotchas, and the folklore about technicalities that automatically end a case does not reflect how these hearings run.
What is true, and less often said, is that many of these cases resolve before a hearing rather than at one. Reductions to a lower-point or non-moving violation are common in a lot of courts, and they are negotiated rather than won. Whether that is available where you are is a local question.
What this site can and cannot tell you
We can tell you what the ticket is likely to cost, what points your state assigns, whether traffic school is open to you, where your state’s criminal line sits if it has one, and what your state’s own documents say — each with the citation it came from.
We cannot tell you whether to contest yours. Nobody who has not read your citation can, and a site that gives everybody the same answer is not answering the question. What we have tried to do instead is make the size of the decision visible, because the most common mistake here is not choosing wrong — it is paying a citation without knowing that the number on it was the small part.
Start with your state’s page for the figures and the mechanism, and check the deadline before anything else.
