Colorado is not a no-fault state. It operates under an at-fault (tort) system, meaning the person who caused the crash is generally responsible for the resulting damages. Despite this, confusion is common, particularly when insurers refer to your own policy or use “no-fault” language loosely.
After a car accident in Colorado, one of the most common questions is whether the state follows a “no-fault” system. This distinction matters when pursuing personal injury compensation. It affects whether you can bring a claim against another driver, what evidence is needed to prove fault, and how insurance coverage applies.
At Ogborn Mihm, our Denver personal injury attorneys regularly handle cases involving disputed liability and complex insurance issues, including those involving head trauma and other life-changing consequences. In this article, we explain how Colorado car accident laws apply in practice and how they shape your options after a crash.
Colorado does not follow a no-fault system. It uses an at-fault, or tort, approach, where responsibility for a crash determines how compensation is pursued. Understanding this distinction is key to knowing what options may be available and how a claim is likely to be handled.
In a no-fault system, drivers turn to their own insurance for certain losses after a crash, regardless of who caused it. This is usually handled through personal injury protection (PIP) coverage, which pays for medical costs and related expenses up to a set limit, without needing to establish fault.
In Colorado’s at-fault system, liability is central from the outset. To recover compensation, you must show that another party’s negligence caused the crash and the losses that followed. This brings the focus onto how the collision occurred, including the actions of each driver, the sequence of events, and whether there is supporting evidence such as witness statements or a police report.
Colorado’s tort system means you are not limited to your own insurance after a crash. You may be able to pursue a claim against the driver who caused the accident. Your own coverage can still play a role in certain situations, but the direction of the claim will usually depend on establishing who is responsible.
Colorado previously operated under a no-fault system that required drivers to carry personal injury protection (PIP) coverage. This system was repealed in the early 2000s, with the state fully transitioning to an at-fault model by January 1, 2004. As a result, drivers are no longer required to carry PIP, and claims are now handled based on who caused the accident.
The repeal changed how compensation is pursued after a crash. Instead of relying on your own insurance for initial coverage, claims are typically directed toward the at-fault driver’s insurer. This places greater emphasis on establishing liability, particularly where fault is disputed.
The term “no-fault” is still used in ways that can be confusing. Some policies include optional coverages, such as MedPay, that may pay for certain expenses regardless of fault. Insurers may also direct you to your own policy first, which can create the impression that Colorado still follows a no-fault system.
Confusion about how claims work can affect what happens in the early stages after a crash. When it is not clear that fault must be established, key details may not be recorded at the right time.
In an at-fault system, early evidence often plays a decisive role in a claim. This includes how the vehicles were positioned, what each driver was doing, and whether there were witnesses. If this information is not documented early, it can be harder to establish liability later and recover full compensation.
Car accident claims in Colorado are governed by a set of established legal principles:
Liability must usually be established before compensation can be recovered. This is typically based on negligence, where one party failed to act with reasonable care and caused the accident.
Fault is assessed by looking at how the collision occurred. This may include driver behaviour, road conditions, and whether traffic laws were followed. In some cases, fault is clear. In others, it may be shared or disputed.
Common examples of evidence used to establish fault include:
Colorado applies a modified comparative negligence rule. You can recover compensation if you were partly at fault, provided your share of responsibility is less than 50%.
Any compensation is reduced based on your level of responsibility. For example, if you are awarded $100,000 after a car accident and found to be 20% responsible, your recovery is $80,000.
If you are 50% or more at fault, you may not recover compensation.
Colorado requires drivers to carry minimum liability insurance, commonly referred to as 25/50/15:
These limits may not fully cover losses in catastrophic injury cases.
Optional coverages can affect how a claim is handled. The most common are MedPay and uninsured or underinsured motorist coverage.
MedPay can help cover medical expenses regardless of fault. Uninsured or underinsured motorist coverage may apply where the at-fault driver does not have enough insurance to cover the loss.
If you have been injured in a collision, taking the following steps after an accident can help protect both your health and your legal claim.
Even if your symptoms seem minor at first, you should still seek medical attention. Some serious conditions, such as traumatic brain injuries (TBI) or internal bleeding, may not show symptoms until hours or even days after the collision. A medical evaluation can identify or rule out these issues, ensure appropriate treatment, and create a clear record linking your condition to the accident.
If it is safe to do so, take photographs of the vehicles, their positions, road layout, traffic signs, and any visible damage. These details can help show how the collision happened, particularly in cases involving turning vehicles, lane changes, or rear-end impacts.
Exchange details with the other driver, including name, contact information, vehicle registration, and insurance details. If there are witnesses, ask for their contact information as well.
Be cautious about accepting early settlement offers from insurers. The full impact of a collision, including ongoing symptoms or time away from work, may not be clear in the first few weeks. Early offers are often based on limited information and may not reflect the longer-term consequences of the crash.
Car accident claims in Colorado are governed by a number of important deadlines, including:
Claims arising from motor vehicle accidents are generally subject to a three-year statute of limitations. This applies to both personal injury and property damage claims. If a lawsuit is not filed within this period, the right to recover compensation through the courts is usually lost.
Different rules apply where a government entity may be involved, such as a city vehicle or a road maintenance issue. In these cases, a formal notice of claim must typically be served within 182 days of the incident. Missing this deadline can prevent a claim from proceeding, regardless of its merits.
Insurance policies often require prompt notice of an accident. In practice, this usually means reporting the collision within days, not weeks.
For uninsured or underinsured motorist coverage, policies may also require notice “as soon as practicable” after you become aware that the other driver may not have sufficient insurance. Delays can lead to disputes about coverage, particularly if the insurer argues that late notice affected their ability to investigate the claim.
In cases involving disputed fault, multiple vehicles, or serious harm, timing can affect the availability of evidence. Witness recollections may fade, and physical evidence may no longer be available. Acting early helps preserve the information needed to support your claim.
Below are some of the most common questions our car accident attorneys receive from injured clients.
Your insurer may direct you to use available coverage under your own policy to address immediate costs, particularly for medical treatment. This does not change how fault is assessed. The overall outcome still depends on establishing who caused the collision and pursuing recovery accordingly.
You may still be able to report the collision through the appropriate law enforcement agency and request that a report is created. In Colorado, crash reports are typically available through the responding police department or via the Colorado State Patrol or the Colorado DMV’s online crash report system, depending on who handled the incident.
If the other driver left the scene, the incident should be reported to the police as soon as possible, along with details about the vehicle or driver. Photographs, witness information, or dashcam footage can help establish what happened. Your own uninsured motorist coverage may apply in these situations, depending on the circumstances.
You may be contacted by the other driver’s insurer, but you are not required to provide a detailed statement immediately. It is usually sensible to limit early communication until you have a clear understanding of what happened and how you have been affected.
If the accident happened during your normal commute, it is usually treated as a standard road traffic matter, and any claim is brought against the driver who caused the collision. Fault and insurance apply in the same way as any other accident.
If you were driving as part of your job, such as making deliveries or travelling between work locations, additional coverage may apply. This can include your employer’s insurance or a work-related claim, depending on the circumstances.
Passengers can usually pursue a claim if they were injured in a collision, as they are rarely responsible for the accident. A claim may be brought against the driver of the vehicle you were in, another driver involved, or both, depending on who was at fault.
