Why Motor Claims Are Structurally Slow.

A Claim Is A Supply Chain, Not A Transaction

An insurance policy is a promise, and a claim is the moment the promise is tested. From the insurer's side the test looks like a single event: a customer reports a loss, the insurer investigates, the insurer pays. From the operational side it is nothing of the kind. A single motor claim of ordinary severity can pass through the hands of a policyholder, a first responder, a tow operator, a storage yard, a claims handler, an appraiser or estimator, a collision repairer, one or more parts suppliers, a replacement-vehicle provider, a salvage buyer, a subrogation team, and, where injury is involved, a medical provider and a legal representative on each side.

Each of these parties is an independent commercial entity. Each has its own systems, its own incentives, its own working hours and its own view of the file. None of them reports to the others. The insurer is accountable for the outcome but controls only a fraction of the chain. This is the central structural fact of motor claims, and it does not change when an insurer buys a better claims system, because the claims system only ever sees the insurer's own side of the exchange.

The practical consequence is that a claim spends a great deal of its life waiting. Not being worked on, not being disputed: waiting. Waiting for a vehicle to be moved. Waiting for an inspection to be scheduled. Waiting for a part to arrive. Waiting for an authorisation to come back. Cycle time in claims is overwhelmingly composed of queue time rather than work time, and queue time is a property of the chain, not of any single participant in it.

The Notification Gap

A loss happens at a moment. The insurer learns about it at a later moment. The interval between the two is the first and least examined source of delay in the whole process, and it is almost entirely outside the insurer's control.

During that interval, several things are happening that will shape the cost of the claim and cannot be undone afterwards. The vehicle is being moved, possibly by an operator the policyholder did not choose. Decisions about where it will be stored are being made by whoever arrives first. The physical state of the vehicle, which is the primary evidence in any subsequent dispute about what the collision actually caused, is changing. Third parties with a commercial interest in the claim may be making contact with the policyholder before the insurer has. In jurisdictions with a significant staged-collision problem, this window is exactly where organised activity operates.

Every hour in this interval is an hour in which the insurer is accountable for a file it does not yet know exists. No amount of downstream process improvement recovers it.

Information Is Re-Collected At Every Hand-Off

The second structural problem is that information does not travel well across organisational boundaries. The same facts about a single vehicle and a single event are gathered repeatedly, by different parties, in different formats, for different purposes, and reconciled by hand.

Consider how many times the basic identity of the vehicle is established during one claim: at notification, at tow, at intake to storage, at appraisal, at repair authorisation, at parts ordering, at quality check and at delivery. Consider how many times the damage is described: by the policyholder in their own words, by an estimator in estimating software, by the repairer in a supplement, and potentially by an independent appraiser in a dispute. Each description is made independently, by a party with a different commercial position, at a different point in time, after the physical evidence has degraded a little further.

This is why supplements exist, why they are routine rather than exceptional, and why they are one of the industry's most reliable sources of friction. A supplement is, in the general case, a correction to an assessment made with incomplete information. CCC's 2026 analysis puts the share of United States repairable claims carrying a supplement at roughly 70%, with supplements accounting for something in the range of 20% to 25% of total repair cost. (CCC Intelligent Solutions, Crash Course 2026, March 2026, United States data.)

Verification Is Expensive Because Trust Is Structurally Absent

Insurers must verify. Not because policyholders are dishonest, but because the system cannot distinguish between the honest and the dishonest without doing the work, and the cost of failing to verify is borne by every other policyholder in the pool.

Verification in a motor claim is essentially a question about causation and sequence: was this damage caused by this event, and did it exist beforehand? Answering it well requires evidence captured close to the event, in a form that has not passed through an interested party. Answering it badly, or late, produces two distinct failures at once. Legitimate claims are delayed by friction that exists only because illegitimate claims are possible. Illegitimate claims succeed because the evidence needed to challenge them was never captured.

Most of the industry's fraud spend goes on detecting problems after settlement rather than preventing them before it. That is a rational response to the evidence actually available, and it is expensive. The integrity dimension is set out in full here.

The Cost Tail Nobody Underwrote

The indemnity payment is the visible cost of a claim. It is frequently not the whole cost, and in a slow claim it is not even the fastest-growing part. Several categories accrue with time rather than with severity:

• Towing and recovery. Priced per event and per kilometre, often set by whoever attends the scene rather than by any party to the insurance contract. Several jurisdictions are now legislating on it: the Insurance Council of Australia has called for enforceable caps on accident towing and storage fees across all Australian states and territories, citing Queensland and Western Australia as examples. (Insurance Council of Australia, Motor Insurance Policy Paper, 23 March 2025.)
• Storage and impound. Priced per day. A vehicle that sits for three weeks awaiting an inspection decision accrues three weeks of storage regardless of whether the eventual repair takes two days or twenty.
• Replacement vehicle. Priced per day and tied directly to repair duration. Enterprise Mobility reported United States collision-related length of rental at 15.5 days in the third quarter of 2025, down 0.9 days year over year but still above pre-pandemic levels. (Enterprise Mobility, US Length of Rental Q3 2025.) In Australia, the cost to insurers of providing rental cars rose 70% between 2019 and 2024, which the ICA attributes in part to extended repair wait times. (Insurance Council of Australia, 23 March 2025.)
• Loss adjustment expense. Every additional touch on a file by a human being has a cost that is not part of the indemnity and does not benefit the policyholder.
• Customer retention. CCC's analysis found that in 40.4% of United States collision claims resulting in a total loss, the insured moved to another carrier. (CCC Intelligent Solutions, Crash Course 2026, citing its 2024 Moments of Truth study.) The claim is the single most consequential service interaction an insurer has, and it is the one that goes wrong most visibly.

These are not obscure line items. They are openly discussed at every claims conference in every market covered on this site. They are listed here because they explain why duration, not severity alone, is the variable an operations leader actually manages.

Duration Is The Master Variable

Three separate costs move together with the length of a claim. Storage accrues daily. Replacement vehicle accrues daily. Adjuster attention accrues per touch, and long claims attract more touches. Meanwhile the probability of dispute rises with time, because memories fade, evidence degrades and representation arrives.

This is the reason the industry has spent two decades trying to compress cycle time, and the reason it remains hard. The levers available to a single insurer act on the insurer's own steps. The delay is mostly in the joints between steps, and the joints belong to nobody.
