First 72 hours after a car accident: an action sequence
The first 72 hours after a motor vehicle collision determine the strength of the injury claim. This guide lists every action a claimant must take in that window, in the exact order, with the legal reason behind each step.
First 72 hours after a car accident: an action sequence
A car accident claim is built or destroyed in the first 72 hours after impact. Police reports, medical records, photographs, and witness contact information that exist in this window are admissible evidence in every state. Information that is not captured in this window cannot be reconstructed later. This article specifies the exact sequence of actions a claimant must take, with the legal purpose of each step.
At the scene: minutes 0 to 60 after impact
A claimant at the scene of a motor vehicle collision must complete five tasks before leaving the location: confirm injuries and dial 911 if anyone is hurt, photograph all vehicles and the road, exchange identification and insurance information with every driver, collect contact information from every witness, and remain at the scene until law enforcement arrives.
State duties after a collision that causes injury or significant property damage
Every U.S. state requires drivers involved in a collision that causes injury, death, or property damage above a state-specific threshold to remain at the scene, exchange identification, and report the accident to law enforcement. Leaving before fulfilling these duties converts a civil matter into a criminal hit-and-run charge in all 50 states. The property damage threshold varies: California sets it at $1,000, Texas at $500, New York at $1,001, and Florida at any visible damage.
Photographs that hold up as accident reconstruction evidence
A claimant should capture at least 30 photographs at the scene of a car accident: wide-angle shots of vehicle positions before any vehicle is moved, license plates of all involved vehicles, close-ups of every point of impact damage, skid marks on the roadway, debris fields, traffic control devices, road conditions (wet, icy, gravel), visible injuries to the claimant, and any obstructed sightlines. Photographs that include a device timestamp are admissible in every state under self-authentication rules.
Calling police: when reporting is mandatory and when it is optional
Police must be called to a car accident scene any time a person is injured, a death occurs, a driver appears impaired, or property damage exceeds the state-set threshold. A police accident report is the single most-cited piece of evidence in personal injury settlement negotiations. Drivers who do not call police lose access to an officers diagram, the at-fault designation, and the officers contemporaneous notes.
How to request a copy of the police accident report
A claimant should request the police accident report from the responding agency 5 to 10 business days after the collision. Most agencies charge between $10 and $25 for a certified copy. California Highway Patrol delivers reports through the CHP-411 form. Texas Department of Public Safety releases reports through the Crash Records Information System (CRIS) for $6.00 for an uncertified copy. New York State Police charge $10.00 for a certified MV-104A report.
First medical visit: why a same-day record is the most valuable evidence in the file
A claimant should visit a medical provider on the same day as the car accident, regardless of how the claimant feels at the scene. Soft tissue injuries, concussions, and internal injuries often produce no symptoms for 24 to 72 hours after impact. A medical record dated the day of the accident establishes the temporal connection between the collision and the injury, which is the strongest evidence against an insurance defense that the injury came from a later, unrelated event.
Documentation a claimant should request from every medical provider
- Itemized billing record for every visit, with CPT and ICD-10 codes.
- Clinical notes including the providers description of the mechanism of injury.
- Imaging reports (CT, MRI, X-ray) with the radiologists narrative, not just the images.
- Treatment plan stating prognosis, expected duration, and recommended follow-up.
- Work status form if the provider restricts the claimant from working.
Insurance reporting within 24 hours: what to say and what to refuse
A claimant should report a car accident to their own insurance company within 24 hours of the collision, but should refuse to give a recorded statement to the at-fault drivers insurance company without legal counsel present. Recorded statements are designed to extract admissions that limit insurer liability: statements about speed, prior injuries, or fault are routinely used against claimants in settlement negotiations. See the companion guide on what to say to insurance adjusters in the first call for the specific phrases.
Acceptable initial statements to the claimants own insurer
The claimant should provide the following facts to their own insurance company in the first call: date and location of the accident, names and license plate numbers of involved vehicles, the police report number if available, and the name of the medical provider who examined the claimant. The claimant should not speculate about speed, fault, or prior medical conditions. Any uncertainty should be expressed as "I do not remember" or "I do not know."
Photographing visible injuries: a daily protocol for the first week
A claimant should photograph every visible injury daily for at least seven days after a car accident. Bruising, swelling, and abrasions evolve over a predictable timeline: bruises darken between days 2 and 4, peak between days 5 and 7, and fade between days 10 and 14. A photographic record of this progression corroborates medical testimony about the severity of soft tissue injury.
Common 72 hour mistakes that close a viable claim
- Signing a release before the medical picture is complete. Many insurers offer a quick low-five-figure settlement within 72 hours, before the claimant knows the extent of injury. A signed release ends the claim permanently.
- Giving a recorded statement to the at-fault drivers insurer. Adjuster questions are designed to lock in versions of events that favor the insurer.
- Posting on social media about the accident. Insurance defense teams routinely subpoena social media accounts; posts contradicting medical claims are used to reduce settlement value.
- Delaying medical care. Any gap longer than 72 hours between the accident and the first medical visit creates a defense argument that the injury came from another cause.
When to retain a personal injury attorney
A claimant should retain a personal injury attorney within 72 hours of a car accident if any of the following conditions apply: a medical provider has diagnosed an injury that may require ongoing treatment, the claimant has missed work or expects to, the at-fault drivers insurer has contacted the claimant, the police report does not assign fault clearly, or the claimant is uncertain about the value of the claim. Initial consultations are free in every U.S. state. Most personal injury attorneys work on a contingency fee, meaning the claimant pays nothing up front and the firm collects a percentage of any recovery (see how contingency fees work).
