Whether you're legally required to report a crash depends on your state — but in most states reporting is mandatory when there's an injury, a death, or property damage above a set dollar threshold. Even when it isn't required, a police report is one of the most useful documents a claim can have. The exact reporting rules and dollar thresholds vary by state, so check your own state's DMV or motor-vehicle agency.
Most states require you to report a crash — to police, the DMV, or both — when someone is injured or killed, or when property damage passes a dollar threshold the state sets. Some states give you a deadline to file a written report if police didn't respond. Because the threshold and the deadline differ by state, confirm yours with your state's motor-vehicle agency.
A police report captures the date, location, vehicles, drivers, often a diagram, and sometimes the officer's notes on what happened and whether a citation was issued. Insurers and, later, a court treat it as a neutral, contemporaneous record. Having one can make a claim move faster and reduce 'he said, she said' disputes about the basics.
Ask the responding officer for the report number before you leave the scene. Reports are usually available a few days to a couple of weeks later from the responding agency — often a city police department, county sheriff, or state highway patrol — sometimes online, sometimes in person, often for a small fee. Keep a copy with your photos and notes.
In busy areas or minor crashes, officers may not respond. If that happens, document the scene thoroughly yourself — photos, witness contacts, the other driver's information — and ask whether you can file a report at the station or online. Several states let or require you to submit a self-report form within a set number of days; your DMV's website will say.
