How to Fight a Red-Light Camera Ticket in Colorado (2026)

Q: Does a Colorado red-light camera ticket add points to my license?

No. Under C.R.S. § 42-4-110.5(3) (effective June 1, 2024), the department has no authority to assess points for automated enforcement violations, and the violation is not kept in DMV official records. There is no insurance channel.

Q: What is the Colorado no-collection-without-personal-service rule?

Under C.R.S. § 42-4-110.5(2)(a)(IX), no state, county, city, or municipality may initiate or pursue a collection action against a registered owner for an unpaid camera penalty unless the owner was personally served — in person by a process server — with the Notice of Violation or the Final Order of Liability. A mailed-only NOV does not satisfy this requirement. If you received only a mailed NOV and are facing collection pressure, this is a statutory defense to the collection action (though it does not dismiss the underlying ticket).

Q: How long do I have to respond to a Colorado camera NOV?

The response deadline must be at minimum 45 days from the NOV issuance date (C.R.S. § 42-4-110.5(2)(a)(IV)). The NOV itself must have been issued within 30 days of the alleged violation for in-state vehicles (60 days for out-of-state). Missing the response deadline waives your right to contest the violation and penalty amount.

Q: Can I fight a Colorado red-light camera ticket if the notice was mailed late?

Yes. Under C.R.S. § 42-4-110.5(2)(a)(II)(A), the NOV must be issued and sent to the registered owner no later than 30 days after the violation (in-state vehicle). If the NOV was postmarked more than 30 days after the violation date, it is untimely and should be dismissed. Check the postmark on the envelope.

Q: What signage is required before a Colorado red-light camera location?

Under C.R.S. § 42-4-110.5(2)(d)(II), a sign must be placed not fewer than 200 feet nor more than 500 feet before the red-light camera, with lettering at least 4 inches high for uppercase letters and 2.9 inches for lowercase. A border or jurisdictional sign alone does not satisfy this requirement.

Colorado red-light camera tickets are civil penalties under C.R.S. § 42-4-110.5 (as amended by SB 23-200, eff. June 5, 2023). There are zero points and violations are not reported to DMV (§ 42-4-110.5(3)). Fine cap is $75 including all surcharges. Colorado's most unusual rule: no collection action may be pursued unless the owner was personally served the NOV or final order of liability (§ 42-4-110.5(2)(a)(IX)). The NOV must be issued within 30 days of the violation (in-state vehicles), and you have at minimum 45 days from the NOV date to respond.

Your Defenses in Colorado

Defenses are ranked by strength: high, medium, conditional. Statutory hooks are traceable to primary-source legal research verified 2026-06-07.

Late Notice of Violation — 30-Day Issuance Window

high

Under C.R.S. § 42-4-110.5(2)(a)(II)(A), the jurisdiction must issue and send a Notice of Violation to the registered owner no later than 30 days after the alleged violation if the vehicle is registered in Colorado (60 days if out-of-state registered). If the NOV was issued or postmarked more than 30 days after the violation date for an in-state vehicle, the notice is untimely and enforcement is barred.

C.R.S. § 42-4-110.5(2)(a)(II)(A)-(B) — 'within thirty days after the alleged violation occurred if the motor vehicle involved in the alleged violation is registered in the state; or within sixty days after the alleged violation occurred if the motor vehicle involved in the alleged violation is registered outside of the state.' Source: content.leg.colorado.gov/sites/default/files/2023a_200_signed.pdf (SB 23-200, signed June 5, 2023)

The postmark date on the envelope controls, not the date you received the notice. Check the envelope before using this defense. If the postmark is within 30 days of the violation date (in-state vehicle), this defense does not apply.

No Collection Action Without Personal Service

high

Under C.R.S. § 42-4-110.5(2)(a)(IX), the jurisdiction 'shall not initiate or pursue a collection action against a registered owner of a motor vehicle for a debt resulting from an unpaid penalty assessed pursuant to this section unless the registered owner is personally served the notice of violation or the final order of liability.' A mailed-only NOV does not satisfy personal service. This defense blocks collection enforcement — it does not dismiss the underlying ticket.

C.R.S. § 42-4-110.5(2)(a)(IX) — 'The state, a county, a city and county, or a municipality shall not initiate or pursue a collection action against a registered owner of a motor vehicle for a debt resulting from an unpaid penalty assessed pursuant to this section unless the registered owner is personally served the notice of violation or the final order of liability.' Source: content.leg.colorado.gov/sites/default/files/2023a_200_signed.pdf (SB 23-200, p. 6)

This defense blocks collection only — it does not dismiss the underlying ticket or invalidate any final order of liability. If you have already been personally served in person with a Penalty Assessment Notice or Final Order of Liability by a process server, this defense does not apply to that service. Do not use this letter to ignore a court summons.

Owner Was Not the Driver — Evidence of Non-Operation

high

Under C.R.S. § 42-4-110.5(2)(h), the state, county, or municipality may NOT require the registered owner to disclose the identity of the driver detected through the automated system. The owner may be required to submit evidence that the owner was not the driver, but cannot be compelled to name the actual driver. This is confirmed by the Denver DPD FAQ: 'You are not required to nominate (or identify) the driver in order to have your Not Pictured Affidavit reviewed by the Denver Police Department.'

C.R.S. § 42-4-110.5(2)(h) — 'The state, a county, a city and county, or a municipality shall not require a registered owner of a vehicle to disclose the identity of a driver of the vehicle who is detected through the use of an automated vehicle identification system. However, the registered owner may be required to submit evidence that the owner was not the driver at the time of the alleged violation.' Source: content.leg.colorado.gov/sites/default/files/2023a_200_signed.pdf (SB 23-200, p. 9)

You must have actually not been the driver. Submitting a false statement that you were not the driver may subject you to criminal prosecution. Denver Revised Municipal Code § 38-40 (False Information) applies in Denver; equivalent ordinances exist in other CO jurisdictions.

Signage Non-Compliance

medium

Under C.R.S. § 42-4-110.5(2)(d), the jurisdiction must post a sign notifying the public that an automated vehicle identification system is in use. For speed cameras, the sign must be in a conspicuous location not fewer than 300 feet before the area of system use. For red-light cameras, the sign must be placed not fewer than 200 feet nor more than 500 feet before the camera system, with specified minimum lettering sizes. A border or jurisdictional sign alone does not satisfy this requirement.

C.R.S. § 42-4-110.5(2)(d)(I) — speed cameras: sign 'in a conspicuous place not fewer than three hundred feet before the area in which the automated vehicle identification system is to be used.' C.R.S. § 42-4-110.5(2)(d)(II) — red-light cameras: sign 'placed in a conspicuous location not fewer than two hundred feet nor more than five hundred feet before the automated vehicle identification system' with minimum lettering sizes. Source: content.leg.colorado.gov/sites/default/files/2023a_200_signed.pdf (SB 23-200, pp. 6-7)

This defense is strongest when supported by documentary evidence (photographs of the sign or its absence, GPS measurements of sign distance). Dismissal on signage grounds may be discretionary at the administrative level.

Plate Misread or Wrong Vehicle in Photo

medium

Under C.R.S. § 42-4-110.5(6)(a)(I), the automated system simultaneously records a photograph of the vehicle, the operator, and the license plate at the time of the alleged violation. A Notice of Violation is issued to the registered owner of the vehicle identified in that photograph. If the plate number shown is not the owner's plate, or the vehicle in the photograph is a different make, model, or color from the owner's vehicle, the notice was erroneously issued. Denver DPD FAQ explicitly lists 'plate misread' as a basis for cancellation.

C.R.S. § 42-4-110.5(6)(a)(I) — system 'simultaneously record[s] a photograph of the vehicle, the operator of the vehicle, and the license plate of the vehicle'; notice is issued to 'the registered owner of the motor vehicle involved in the alleged violation' (§ 42-4-110.5(2)(a)(II)). Source: content.leg.colorado.gov/sites/default/files/2023a_200_signed.pdf; denvergov.org photo radar page

Before filing, review the enforcement photographs if available (the URL to view evidence is printed on the Notice of Violation). If the photograph clearly shows your plate and your vehicle, this defense does not apply.
