How to Fight a Speeding Ticket in Colorado (2026)

Thinking about whether to fight a speeding ticket in Colorado? You may be able to get it reduced or dismissed — but only if you act before the deadline on your citation and follow Colorado’s actual contest process. This guide walks you through exactly how to fight a speeding ticket in Colorado: the steps to plead not guilty, the deadlines, the defenses that tend to work, and whether to do it yourself or hire an attorney. All information is general guidance, verified against Colorado sources as of June 2026.

How to Fight a Speeding Ticket in Colorado

Colorado uses an in-person arraignment process. When you receive a speeding citation (called a Penalty Assessment Notice), you have the option to plead not guilty on or before the court date printed on your ticket. You may enter your not-guilty plea in person at the courthouse, by mail, or through an attorney (Colorado allows a defendant to plead not guilty by counsel or written motion without being present).

For traffic infractions (speeding under 25 mph over the limit), the court schedules a final hearing where a county magistrate decides your case.

For traffic offenses (25+ mph over), the court sets a pre-trial conference where you or your attorney can negotiate with the district attorney, and if no agreement is reached, the case proceeds to trial before a judge or jury. Many Colorado county and municipal courts also allow you to contact the court clerk by phone or online to enter your plea and schedule your hearing date without appearing in person for arraignment.

How to plead not guilty: (1) Review your citation for the court name, address, and appearance date. (2) Contact the court listed on your ticket before the appearance date — many courts accept a not-guilty plea by phone, mail, or in person at the clerk’s window. You may also enter your plea through an attorney or by written motion filed with the court.

(3) At arraignment (your first court appearance), the judge or magistrate informs you of your rights and asks for your plea — state “not guilty.” (4) The court then schedules either a final hearing (for infractions) or a pre-trial conference (for misdemeanor traffic offenses). (5) Prepare your defense, gather evidence, and appear on your scheduled hearing date.

Your discovery rights: Yes, but with important limitations depending on case type. For traffic offenses (misdemeanor-level, 25+ mph over), defendants may request discovery of the prosecution’s case file at any time after the complaint has been filed — this can include the officer’s notes, radar/lidar calibration certificates, device maintenance records, dashcam or body camera footage, and training records.

For traffic infractions (most speeding tickets under 25 mph over), discovery rights are more limited — under the Colorado Rules for Traffic Infractions, a defendant is generally not entitled to inspect the prosecution’s documents until the day of the final hearing, at which point you may inspect the documents the officer intends to use as evidence.

To request discovery, file a written or oral motion with the court and send your request to both the citing law enforcement agency’s records division and the local prosecuting agency.

Common Defenses That Work in Colorado

Depending on the facts, drivers who fight a speeding ticket in Colorado may be able to raise defenses such as:

• (1) Radar or lidar calibration challenge — request the device’s calibration records and maintenance logs
• if the agency cannot produce current calibration documentation
• the speed reading’s reliability is in doubt. (2) Officer training challenge — question whether the officer was properly trained and certified to operate the specific radar or lidar unit used. (3) Pacing error — if speed was determined by pacing (following your vehicle)
• challenge the accuracy of the officer’s speedometer calibration and the distance and duration of the pace. (4) Signage defense — if the speed limit sign was missing
• obscured by vegetation
• knocked down
• or displaying incorrect information
• you may not have had proper notice of the speed limit. (5) Necessity or emergency — if you were speeding due to a genuine emergency (medical emergency

No defense is guaranteed — whether one applies depends entirely on your situation, so check with your court.

DIY vs. Hiring an Attorney in Colorado

Many drivers can handle a basic speeding infraction (under 25 mph over the limit) on their own, especially if they have a clean driving record, the fine is modest, and they are comfortable appearing in court. DIY is most practical when you have a clear defense (missing signage, calibration issues, officer no-show). However, you should strongly consider hiring a Colorado traffic attorney if: (1) you were cited for 25+ mph over the limit, which is a misdemeanor criminal offense that can carry jail time; (2) you are a CDL holder and points could affect your livelihood; (3) you already have points on your license and are at risk of suspension; (4) you want to negotiate a reduction to a non-moving violation or deferred judgment; (5) you cannot attend court in person and need an attorney to appear on your behalf; or (6) the ticket involves reckless driving, careless driving, or other serious charges alongside speeding.

If you contest and lose: If you plead not guilty and lose at trial, you will owe the original fine plus mandatory court surcharges, a docket fee of approximately 21 dollars (16-dollar base plus a 5-dollar surcharge), and any additional court costs. The DMV points assessed to your license remain the same whether you pay the ticket or lose at trial — Colorado does not add extra points for contesting.

However, if you delayed payment by going to trial, you will not have the option to attend traffic school in lieu of points in some jurisdictions.

Your insurance rates may increase once the conviction appears on your driving record. For misdemeanor speeding (25+ mph over), a conviction after trial can result in up to 90 days in jail and a fine up to 300 dollars, though jail is rare for first offenses. You may appeal an unfavorable verdict to district court within 35 days, but this adds additional legal costs.

Why Fighting a Colorado Ticket Can Be Worth It

Paying a Colorado speeding ticket is an admission of guilt — it adds points and can raise your insurance for years. That is why many drivers decide to fight a speeding ticket in Colorado even over a modest fine: avoiding the points and the surcharge can save far more than the ticket.

What Happens When You Fight a Colorado Ticket

Choosing to fight a speeding ticket in Colorado starts with a not-guilty plea, which you enter by the deadline on your citation. From there the case is set for a hearing where the officer who wrote the ticket usually has to appear and prove the violation. If the officer does not show up, the case is often dismissed. If they do, you get a chance to question the evidence — how your speed was measured, whether the equipment was calibrated, and whether the signage and conditions were clear.

Paying the ticket instead is treated as pleading guilty, so it adds the points and the insurance surcharge automatically. That is the trade-off: fighting costs you time and possibly an attorney fee, but it is the only path that can avoid the points entirely. No outcome is guaranteed — courts decide each case on its facts — so weigh the likely savings against the effort. Many drivers in Colorado can handle a straightforward first ticket on their own, while a high-speed or criminal-speed charge is usually worth an attorney.

If you do decide to fight a speeding ticket in Colorado, stay organized: note every deadline on your citation, keep copies of everything you file, and arrive early on your court date. Being prepared and respectful in court will not guarantee a win, but it gives you the best chance and avoids missing a step that could cost you the case automatically.

What to Do About Your Colorado Speeding Ticket

Once you have a Colorado speeding ticket, you generally have three choices, and the right one depends on the points involved, your driving record, and your insurance:

• Pay it — the fastest option, but paying is an admission of guilt that adds points and can raise your premium for years.
• Fight it — contesting can get the ticket reduced or dismissed, especially if the officer does not appear or the evidence is weak. See how to fight a speeding ticket in Colorado.
• Take traffic school — if you qualify, a state-approved course can keep points off your record. See the Colorado traffic school guide.

Before deciding, it helps to know the full cost — use our speeding ticket cost calculator and the Colorado points guide to see how close a ticket puts you to a suspension. There is no single right answer for everyone; the best choice depends on how many points the ticket adds, what your record looks like, and how much your insurance would rise.

Other Colorado rules to know: (1) Colorado classifies speeding into two tiers: under 25 mph over the limit is a class A traffic infraction (civil), while 25 mph or more over is a class 2 misdemeanor traffic offense (criminal) with potential jail time. (2) For infractions, the burden of proof is on the prosecution to prove liability beyond a reasonable doubt — the same standard as criminal cases, which is unusually high for a civil traffic infraction.

(3) A defendant may enter a not-guilty plea through an attorney or by written motion without personally appearing in court. (4) Colorado does not have a statewide online portal for contesting tickets — procedures vary by county and municipal court, so check with the specific court on your citation.

(5) Photo radar and red-light camera tickets have special rules — under Colorado law, photo radar citations must be served within 90 days and the driver can request a hearing; some municipalities have banned photo radar entirely. (6) Deferred judgment may be available — the court may allow you to plead guilty with the agreement that the conviction will be dismissed after a probationary period if you commit no further violations, keeping points off your record.

(7) You cannot collaterally attack the validity of a traffic infraction judgment more than 6 months after it was entered.
