Colorado Highway Speed Enforcement Cameras: Fines and Warnings

Colorado’s speed camera laws allow automated enforcement in school zones, residential streets, construction and maintenance zones, streets bordering municipal parks, designated corridors, and, since 2023, interstate highways operated by the state. Tickets are civil penalties capped at $40 in most locations and up to $75 or $80 in work and school zones, carry no license points, and are not reported to insurance companies. Ignoring one, however, sets off an escalation that adds service fees and eventually strips your right to contest.

Where Colorado Allows Speed Cameras

Before 2023, automated speed enforcement in Colorado was limited to four settings: school zones, residential neighborhoods, construction and maintenance zones, and streets adjacent to municipal parks. Senate Bill 23-200 expanded that authority by creating a new “automated vehicle identification corridor” that counties and municipalities can designate for camera enforcement, and by authorizing the Colorado Department of Transportation to place cameras on interstate highways. Local governments cannot put cameras on the interstates; only CODOT can.¹

New camera installations have to be announced on the jurisdiction’s website at least 30 days before activation, and the cameras are limited to issuing warnings for the first 30 days of operation.¹

Signage: The 300-Foot Rule

Every speed camera location must have a warning sign posted at least 300 feet before the camera, whether it sits in a work zone, a school zone, or a designated corridor.² For corridors, a permanent sign must appear at least 300 feet before the corridor starts, with additional signs at least 300 feet before each camera inside it.³ Red-light cameras and other non-speed enforcement use a different band, between 200 and 500 feet. Missing signage is a legitimate ground for challenging a citation.

The First-Violation Warning

If a camera catches you at less than 10 mph over the limit and it’s your first violation as the registered owner, the jurisdiction can only send you a warning. No fine, no surcharge.² After that first warning, later violations at any speed over the limit can trigger a full citation. Some local jurisdictions set stricter thresholds than the state floor; certain mountain towns, for instance, only issue $40 citations at 11 mph or more over the limit.

How Much the Fines Are

The caps are intentionally low compared to an officer-issued ticket:

Corridors: maximum $40, including any surcharges.
School zones: the $40 cap doubles to $80.²
CODOT’s highway program: $75 in work and school zones, $40 in designated corridors.³

An officer-issued speeding ticket, by contrast, can run several hundred dollars once surcharges are added. The camera program’s deterrent effect is meant to come from consistency of detection, not the size of each penalty.

No Points, No Insurance Impact

Camera-generated speed citations do not add points to your Colorado driver’s license.² They are civil violations rather than traditional traffic infractions. Because no points are assessed, they are not reported to insurance companies, so a camera ticket will not raise your premium.⁴ That’s a real difference from a ticket handed to you at a traffic stop, which carries points and appears on your driving record.

What the Notice of Violation Must Include

The notice arrives by mail and has to include a photograph of your license plate, the recorded speed, and the posted speed limit at the time. Most jurisdictions add a website and a unique citation number so you can pull up the photos and video of the alleged violation before deciding what to do.⁴ Reviewing the evidence is worth the few minutes it takes, especially if the speed reading looks off or you want to confirm the camera captured your vehicle.

The mailing deadlines matter. The jurisdiction must send the notice within 30 days of the violation for Colorado-registered vehicles, or within 60 days for out-of-state vehicles. A late notice can be grounds for dismissal.²

Paying the Ticket

Most jurisdictions accept online payment through a portal listed on the notice, along with credit card, debit card, or a mailed check or money order. The deadline printed on the notice must give you at least 45 days from issuance to pay or request a hearing.² Don’t miss it. The escalation process runs automatically once that date passes.

How to Contest It

You can request a hearing to dispute the violation. The request has to be submitted in writing by the deadline on the notice, which is at least 45 days from issuance. The case then proceeds to the county court where the violation occurred or the relevant municipal court.¹

Common grounds include missing or improperly placed signage, a notice mailed after the statutory deadline, a photograph too unclear to identify the vehicle, or proof that the vehicle was reported stolen at the time. Colorado law does not require you to identify who was driving, but you can submit evidence showing you were not the driver.¹

What Happens If You Ignore It

The escalation runs on a fixed track:

Initial notice: at least 45 days to pay or request a hearing.
Civil penalty assessment: if you do nothing, the jurisdiction issues a second, more urgent notice within 30 days.³
Personal service: still no response, and the jurisdiction may send a process server. Denver adds a minimum of $29 for personal service, and the actual charge can be higher depending on the cost of locating you.⁴
Final order of liability: miss the civil penalty deadline and you waive your right to contest. The jurisdiction enters a final order against you as the registered owner.¹

A $40 corridor ticket can end up costing $70 or more once service fees are tacked on, and by then the ability to dispute the charge is gone. Handling the ticket inside that first 45-day window is cheaper and preserves your options.

If Someone Else Was Driving Your Car

Colorado holds the registered owner liable for the civil penalty regardless of who was behind the wheel, and the state does not require you to identify the driver.³ If a friend borrowed the car, or a renter was driving, the ticket lands with you.

You have two practical paths. Pay it and collect from the driver yourself, or submit evidence to the jurisdiction that you were not driving; the specific process varies by municipality. If the vehicle was stolen or had been sold before the violation, you can dispute the ticket with documentation of the theft report or sale.³

Out-of-State Drivers

If a Colorado camera catches an out-of-state vehicle, the notice goes to the registration address within 60 days rather than the 30-day window that applies to Colorado plates.² Because these are civil violations without points, they generally are not reported to your home state through the Driver License Compact, which mainly covers point-bearing moving violations and license suspensions. Your home DMV and insurer are unlikely to hear about a $40 camera ticket from Colorado.

Ignoring the notice does not make it go away. The same escalation applies, and a final order of liability can still be entered against the registered owner. Whether Colorado actively pursues collection across state lines over a small fine is a separate practical question, but the legal authority to do so exists.
