What Happens After a Car Accident: Step by Step

Most people go years between accidents — which means most people are navigating the repair process from scratch, while stressed, on a deadline, without their car. Here's the entire sequence, explained by a shop that's guided Milwaukee County drivers through it since 1964.

Step 1: At the Scene (and the First 24 Hours)

• Safety first, then documentation. Move out of traffic if drivable, check on everyone, call 911 if there are injuries or significant damage. Wisconsin requires reporting crashes involving injury or property damage over $1,000 — when in doubt, report.
• Photograph everything: all four corners of both vehicles, close-ups of damage, the scene, license plates, the other driver's insurance card.
• Exchange information, admit nothing. Fault gets sorted out later, with evidence.
• If it's not drivable, you choose where it gets towed. Sending it straight to your chosen body shop skips storage fees at a tow lot and gets the estimate started sooner.

Step 2: The Claim — and a Right Most Drivers Don't Know They Have

Report the accident to your insurer (or the at-fault driver's insurer). They'll assign a claim number — hold onto it; every later step references it.

Not sure the damage is even worth a claim? We wrote a separate guide for that: Should you file an insurance claim for a fender bender?

Step 3: The Estimate

Bring the car (or have it towed) to the shop. At Root River, estimates are free and written, no appointment necessary. We photograph and document the damage and share the estimate directly with your insurance company, speaking their language so nothing gets missed or lowballed.

Expect the insurer's initial approval to cover the visible damage — that's normal, and it's what supplements are for (Step 5).

Step 4: Parts & Scheduling

Once the repair is approved, parts get ordered — and here's a tip that saves days: a good shop orders parts before you drop the car off whenever possible, so your vehicle isn't sitting disassembled waiting on a bumper. You'll also settle the parts question — OEM, aftermarket, or recycled — which we explain honestly in our parts guide.

This is also when you arrange transportation. If your policy includes rental coverage, you can use it — or skip the rental counter entirely with one of our free loaner cars.

Step 5: Teardown & the Supplement

With the car in the shop, damaged areas are disassembled — and this is where hidden damage shows itself: a bent reinforcement bar behind an intact-looking bumper, a tweaked suspension mount behind a crumpled fender. The shop documents it and files a supplement with the insurer for the additional repairs.

Supplements are routine, not a red flag — the red flag is a shop that doesn't find hidden damage. Insurance pays for the supplement the same way it paid the original estimate.

Step 6: Structural & Body Repair

Now the actual fixing: frame or unibody straightening on precision measuring equipment to restore factory specifications, panel repair or replacement, welding, and alignment of every gap and body line. This is the heart of collision repair — and the part that determines whether your car drives straight and protects you properly in any future accident.

Step 7: Paint

Repaired and replaced panels are prepped, primed, and refinished with computerized color matching, then blended into surrounding panels and clear-coated. Done right, you will not be able to find the repair — that's the standard.

Step 8: Reassembly, Inspection & Pickup

Trim, lights, and hardware go back on; systems are checked; the vehicle is cleaned and inspected against the estimate line by line. You get your car back looking like the accident never happened — at Root River, backed by a lifetime guarantee on the workmanship.

How Long Does All This Take?

Parts availability is the wildcard — which is why the pre-ordering in Step 4 matters, and why a realistic timeline up front beats an optimistic one that slips.

The Short Version
