How to Deal With the Other Driver’s Insurance After an Accident

September 10, 2026

The other driver’s adjuster will usually reach you before your own does, and the call is friendly. That is a professional choice, not a personality. The adjuster’s employer is contractually obligated to defend the person who hit you, and everything gathered on that first call is gathered with that obligation in mind.

This post covers what you actually owe the at-fault driver’s insurer, what you never have to provide, and how these companies price a claim in the weeks before anyone knows what the injury is. Boesen Law’s car accident lawyers in Denver can take the correspondence off your hands entirely, which is usually the cleanest solution.

Colorado Is an At-Fault State, So Their Carrier Pays

Colorado abandoned no-fault insurance in 2003. The at-fault driver’s liability coverage is what pays for the injuries that driver caused, which means the company evaluating your claim is the same company financially harmed by paying it. Anyone unclear on how the system works should start with whether Colorado is a no-fault state for car insurance, because the answer shapes every conversation that follows.

An adjuster is not your adversary in the personal sense. They are measured on cycle time and on the average value of claims closed, and a claim closed early for a modest number scores well on both. None of that requires anyone to behave badly. It only requires you to notice whose interests are being served.

The First Call and What It Is For

Three things are usually collected within the first ten days, and each has a purpose beyond the friendly framing.

A recorded statement. Presented as routine and necessary to process the claim, and requested before most people have read what to do after an auto accident. Its real function is to lock your account of the collision and your description of your symptoms in place on day four, before the diagnosis exists. A statement given while you are on muscle relaxants, describing yourself as “sore but okay,” is quoted back nine months later against a surgical recommendation.

A blanket medical authorization. Presented as required to review your treatment. As written, it typically opens your entire medical history rather than the records related to this crash, which is how a twelve-year-old back complaint becomes the centerpiece of a causation defense.

An early settlement offer. Presented as a convenience while your car is in the shop. Signing it usually releases the bodily injury claim as well.

What You Owe Them, and What You Do Not

Colorado law and basic practicality require some cooperation. Most of what is requested is not in that category.

  • Provide: your name, your contact information, the date, time, and location of the crash, the vehicles involved, and your own insurance information.
  • Provide: access to inspect the damaged vehicle, and the crash report number if one exists.
  • You are not required to give the other driver’s insurer a recorded statement. No Colorado statute compels it, and you have no contract with that company obligating you to sit for one.
  • You are not required to sign a blanket medical authorization. Records relevant to injuries you are claiming can be produced later, in a defined scope, at the appropriate stage.
  • You are not required to speculate about fault, speed, or distances. “I do not know yet” is a complete and accurate answer in the first week.
  • You are not required to accept the first valuation of anything, including your vehicle.

Your own carrier is a different matter. Your policy contains cooperation clauses, and much of what a car accident lawyer does early is separating obligations you genuinely have from requests that merely sound obligatory.

Property Damage and Bodily Injury Are Two Separate Files

They are frequently handled by different adjusters with different authority, and combining them is the single most expensive mistake people make.

Settling the property damage is fine and often necessary. Confirm in writing that the release covers the vehicle only. Releases that quietly encompass bodily injury have ended claims worth many times the repair estimate, and the person signing had a rental car deadline and no reason to read closely.

Photograph the vehicle from every angle before releasing it, particularly on a total loss. Once it is gone, the crush profile and the event data recorder go with it, along with the best available evidence of impact forces. Where the estimate seems low, a review of your available Colorado auto insurance coverages will show whether your own collision coverage gives you a faster route with a deductible you can recover later.

The Early Offer Arrives Before the Injury Does

Offers made in the first month are priced on a repair estimate and an emergency room visit, because that is all that exists yet. What they cannot price is the injection series in month three, the surgical consultation in month six, or the permanent lifting restriction that changes what you earn.

Once the release is signed, none of that reopens. This is the entire reason a fast offer exists, and it is why responding to a low settlement offer starts with the medical picture rather than with a counter-number.

If you are considering an early resolution, the minimum questions are whether every provider has released you from care, whether any recommendation remains outstanding, and whether anyone has calculated the wages lost to appointments and restrictions rather than to days fully missed.

Their Policy Limit May Be the Real Ceiling

The at-fault driver’s coverage is often smaller than people assume. According to the Colorado Division of Insurance, the minimum required liability limits are $25,000 per person for bodily injury, $50,000 per accident, and $15,000 for property damage, and the Division estimates that 15 to 20 percent of drivers are uninsured altogether.

A single night in a Denver hospital can exceed a $25,000 limit before rehabilitation begins. Two facts about your own policy matter enormously in that situation. Medical payments coverage of $5,000 is included unless you rejected it in writing, and it pays regardless of fault and ahead of your health insurance. Uninsured and underinsured motorist coverage is likewise included unless you rejected it in writing, and it is what responds when the at-fault driver cannot cover the harm they caused.

Where the limits run out, what happens when the at-fault driver is underinsured becomes the most important question in the case, and it should be asked early rather than after a release has been signed.

Have You Already Said Too Much?

Jason Carr, a motor vehicle injury attorney at Boesen Law who spent fourteen years as a commissioned officer in the United States Army Reserve Military Police, notes:

“Almost nobody says anything catastrophic on a recorded statement. What they do is speak casually about things that turn out to be technical. They say they are fine, meaning they can walk. They estimate a speed they never saw. They apologize because they are decent people. Nine months later a defense lawyer reads those three answers back in a deposition as though the client testified to them under oath. If you already gave a statement, it is not fatal, but somebody needs to read the transcript now and know exactly what is in it before the next conversation happens.”

Layered coverage is worth mapping at the same time. A commercial policy behind a driver who was working, a household relative’s underinsured motorist coverage, and your own medical payments benefit can all be in play, and none of them are volunteered by the adjuster on the other side.

What Cases Like Yours Have Recovered

  • $275,000 for a client injured in a high-speed rear-end collision who experienced concussion symptoms, whiplash, and continuing significant neck pain with numbness and tingling in the hands.
  • $250,000 for a client T-boned at an intersection with whiplash, a potential concussion, and hip and back pain.

Neither of those figures resembles what an early offer looks like in the first month. Our case results reflect claims documented before they were negotiated.

There is no version of this where you out-negotiate a claims department alone while injured. The imbalance is not about intelligence. It is that they do this several hundred times a year with the file in front of them and you are doing it once, on painkillers, with a rental car due back Friday.

Clients of Boesen Law across Colorado have recovered hundreds of millions of dollars, our phones are staffed around the clock, and there is no attorney fee unless we recover compensation for you. The adjuster’s name, the claim number, and any form they have asked you to sign are all a free, in-person consultation needs to start. Contact Boesen Law before you sign anything.

FAQs About Dealing With the Other Driver’s Insurance in Colorado

Do I have to give the other driver’s insurance company a recorded statement?

No. You have no contract with that company and no statutory obligation to be recorded by it. Declining is ordinary and does not stall the claim, because the information they legitimately need can be provided in writing. Your own insurer is different, since your policy contains a cooperation clause, though even there the statement should be about facts rather than about medical conclusions you are not qualified to reach yet.

Should I sign the medical release the adjuster sent me?

Not as written. Blanket authorizations typically reach your entire medical history rather than the treatment for this crash, and that history is where a causation defense comes from. Records relevant to the injuries you are claiming will be produced through counsel in a defined scope, and there is no legitimate reason for the other side to have your records from a decade ago before anyone has even valued the claim.

How long does the other driver’s insurer have to respond to me?

Colorado’s insurance laws set no fixed timeframe for a carrier to answer your calls or letters, which the Division of Insurance states plainly. The Division can address unreasonable delay with a company directly, and you can file a complaint with it. Silence, however, does not pause anything on your side. A motor vehicle injury claim in Colorado carries a three-year filing deadline, and the statutory clock on personal injury claims runs whether or not the adjuster is returning calls.

They admitted their driver was at fault. Do I still need a lawyer?

Admitted liability settles who caused the crash and says nothing about what the injury is worth, which is where nearly all of the money is. Once fault is conceded, the argument moves to causation, treatment necessity, wage loss, and permanence, and those disputes are decided by medical evidence rather than by the police report. An admission also hands you an advantage that is easy to waste by settling before the treatment is finished.

The adjuster keeps asking why I waited three days to see a doctor. Does that hurt me?

It is a standard line of attack rather than a defect in your claim, and it is answerable. Adrenaline masks soft-tissue injuries for a day or two, and people go to work before they go to a clinic. What matters is that the records from your first visit describe the collision, its date, and the mechanism of injury. A short, explained gap in a well-documented file carries far less weight than adjusters imply when they raise it.
