After a crash, one of the first words you hear from your insurance company is "adjuster." The auto insurance adjuster is the person responsible for looking at your car, documenting the damage, and producing an estimate the insurer uses to determine how much to pay. That estimate feels official -- it arrives quickly, it has line items, it looks final. What surprises most drivers is that it rarely is. Understanding what actually happens during the claims adjuster inspection process, and what comes after, puts you in a far better position to get your car fixed correctly.

What an auto insurance adjuster actually does

The adjuster's job is to evaluate your claim: assess the damage, confirm coverage, and produce a written repair estimate. As the Insurance Information Institute explains, adjusters are professionally trained and licensed, and complex claims may involve more than one specialist on the insurance side.

Adjusters are paid by the insurer, not by you. Most are straightforward professionals working within their company's guidelines. What matters to understand is that their estimate is a starting point based on what they can observe, not a final accounting of everything the repair requires. Until a shop disassembles the car, some damage is simply not visible to anyone.

Our guide on working with your adjuster covers the relationship side of the claim in depth. This post focuses on the inspection event itself.

The three types of adjuster inspection

Not every inspection looks the same. Which format you get depends on your insurer, the severity of the damage, and how far along your area is in adopting photo-based claims technology. The table below outlines the three common types.

Regardless of format, every inspection covers the same ground: visible exterior damage. What it cannot cover is everything behind a panel, inside a frame rail, or buried in the car's electronics. That gap is why supplements exist, and why they are routine on every type of claim.

The claims adjuster inspection process, step by step

Here is how a typical in-person auto insurance adjuster inspection unfolds.

1. Scheduling. After you file the claim, the insurer assigns an adjuster and schedules the visit. On in-shop or drive-in inspections this typically happens within a few business days. The NAIC recommends keeping a log of all dates and conversations -- a habit worth starting from this first call.
2. Walk-around and exterior assessment. The adjuster notes every damaged panel, broken lens, missing trim piece, and paint transfer mark, photographing everything and recording gap measurements to document visible deformation.
3. Underhood and structural review. On front-end impacts the adjuster opens the hood to check the radiator support, core support, and front rail tops. On rear impacts they check the trunk floor and rear rails. This is a visual check -- the car is not disassembled at this stage.
4. Pre-existing damage notation. Anything that appears unrelated to this accident -- prior dents, rust, worn trim -- is noted and typically excluded from the claim. Your own pre-accident photos are the best way to avoid disputes here.
5. Writing the estimate. Using estimating software, the adjuster prices out parts, labor hours, paint materials, and related procedures for every item they documented. The estimate reflects what is visible and does not account for damage that requires disassembly to find.
6. Explaining next steps. A thorough adjuster explains what the estimate covers, how supplements work, and what the payment process looks like. If yours does not, ask.

Why the first estimate is almost never the final one

The adjuster estimate is almost always revised upward once a certified shop takes the car apart. This is not a sign that something went wrong -- it is simply how collision repair works.

What the adjuster can see versus what the shop finds

An adjuster inspects a vehicle that is still assembled. Outer panels, bumper covers, and trim pieces hide the structural members underneath. A crumpled fender tells you the fender is damaged. It does not tell you whether the inner wheelhouse is pushed in, the front rail is kinked behind the bumper beam, or the impact sent a fault code through the airbag control module. You only know those things once the outer parts come off.

I-CAR documents this consistently: indirect damage is frequently overlooked because of where it sits -- a front bumper impact can transfer force to a headlamp assembly in a way that is only visible once the headlamp is removed. Electronics add another layer: a pre-repair scan surfaces diagnostic trouble codes that document sensor and module damage no visual walk-around would catch.

The supplement process explained

When the shop finds damage not covered in the original estimate, they write a supplement: an updated line-item document with photos, part numbers, labor hours, and an explanation of why the damage was not visible at the time of the initial inspection. The insurer reviews it and, in most cases, approves it. Under California Code of Regulations Section 2695.8, if the insurer chooses to reinspect the vehicle in response to a supplement request, they must act within six business days of receiving it. They may send an adjuster back or accept the documentation and photos without a second visit.

Supplements are normal. On any vehicle with meaningful collision damage, one or more supplements is the rule, not the exception. Our full guide on how repair supplements work walks through the documentation and approval process in detail.

The adjuster's first estimate is what the damage looks like from the outside. The supplement is what it looks like once the repair actually starts. Both are expected parts of the same process.

Your rights during the inspection and claim

California law gives you clear protections, and knowing them costs nothing.

You choose the shop

California's Auto Body Repair Consumer Bill of Rights gives you the right to select the repair shop of your choice. The insurer cannot require you to use a specific facility. Insurers may suggest preferred shops -- but suggesting is not requiring.

This matters because preferred shops work within cost structures negotiated with the insurer. A certified shop outside that network can advocate more freely for the repair your car actually needs. See our guide on the collision claim timeline for a fuller look at how this plays out.

You are entitled to a written, itemized estimate

California regulations require insurers to provide written estimates itemized by part and labor cost, and to reasonably adjust estimates prepared by a repair shop of the claimant's choice. If the adjuster's number and the shop's assessment differ, the insurer must work through those differences in writing.

You have recourse if the process stalls

If the insurer is not responding within required timeframes, the California Department of Insurance accepts consumer complaints at 1-800-927-4357. Most claims resolve without this step, especially when a certified shop manages the documentation.

What to do before, during, and after the inspection

Before the inspection

• Document everything yourself. Photograph every angle of the damage in good lighting -- close-ups and wide shots. This record is yours, separate from whatever the adjuster captures.
• Choose your shop first if you can. Ask your chosen shop to receive the adjuster. When a technician is present for the walk-around, they can flag concerns and the supplement process starts in a much better position. Our auto body repair page explains how we coordinate this at Lakeside.
• Gather your records. Pre-accident photos, maintenance records, and the police report all support your claim and document prior condition.

During the inspection

• Be present. Being available to answer questions and point out areas you noticed keeps things moving and makes sure nothing obvious gets missed.
• Ask questions. The NAIC recommends asking the adjuster for a written explanation of their decisions. Ask what the estimate covers, whether supplements are expected, and what the approval timeline looks like.
• Do not agree to a total-loss settlement on the spot. If the adjuster raises total-loss, ask for time to have the vehicle reviewed by your chosen shop first. You have options.

After the inspection

• Review the estimate against your photos. Note anything that looks missing and bring the list to the shop.
• Take the estimate to your chosen shop for review. A certified shop can read the estimate line by line, identify items that are underpriced or missing, and tell you what the supplement process is likely to address once disassembly begins.
• Let the shop manage adjuster communication. Once you choose a shop, they are your point of contact for supplement approvals. You should not have to manage that back-and-forth yourself.

Why calling the shop before the adjuster matters

The most effective move after a collision is choosing a repair shop before the adjuster visits. When you call Lakeside first, we receive the adjuster at our facility, walk the car with them, and build documentation that supports every supplement before it is needed. When the adjuster visits first and the driver brings the finished estimate to a shop later, the shop inherits a document the insurer already considers settled -- supplements still happen but take longer.

We handle the claim from first call to finished repair -- estimates, supplement submissions, adjuster communication, and approvals. Our computer diagnostics capability lets us run a pre-repair electronic scan early, surfacing fault codes and module damage before the insurer's estimate hardens.
