So do you need a police report? If anyone was hurt, yes — call 911 from the scene. If nobody was, it depends on your state and the damage, but a report is almost always worth having, because it's the first record of fault an insurer reads. Below: when to call, what goes in the report, how to get a copy, and what it can and can't do for you.

General Information — Not Legal Advice
01
When to
Call the Police
Call 911 if anyone is hurt. For everything else, the rules vary — but police don't always come.

Call 911 from the scene

Officers usually respond
  • Anyone injured, even slightly
  • A driver leaves or refuses to share details
  • A driver seems impaired
  • Cars blocking traffic
  • Damage to public property

Often no officer comes

File it yourself instead
  • Minor crash, no injuries
  • Cars already moved off the road
  • Both drivers exchanged details
  • Many departments take these online
  • Or at the station, after the fact
⚠️ A police report and a DMV report are two different things
Many states also require a report to the DMV. In California, an SR-1 is due within 10 days if anyone was injured or damage exceeds $1,000 — whether or not police came, and whoever was at fault.
02
What Goes
in the Report
Facts first, then the officer's opinion. Insurers read both — only the facts are easy to correct.

The facts

What was recorded
  • Date, time, location
  • Drivers, owners, insurers
  • Vehicles and visible damage
  • Witness names and contact
  • Road, weather and lighting

The opinion

What the officer concluded
  • Each driver's statement
  • A diagram of the collision
  • The likely cause
  • Any citations issued

Your statement goes in the report. Describe what happened in plain facts — where you were, which way you were going, what you saw. Avoid guessing about speed or apologizing, both of which can be read as admissions later.

03
How to Get
a Copy
You request it from whichever agency responded. Start at the scene.
1
Get the report number before you leave
Plus the officer's name and agency. Without the number, finding the report later takes much longer.
2
Know which agency has it
City police, the sheriff, or state highway patrol — in California, freeway crashes usually go to the CHP.
3
Wait for it to be finalized
Reports usually take a week or more. Open your insurance claim now anyway — give the adjuster the report number.
4
Request it
Online, in person or by mail, depending on the agency. Drivers and owners involved can usually get a copy, sometimes for a small fee.
5
Read it the day it arrives
Check names, plates, insurers and the diagram. Factual errors are easiest to fix early.
04
What the Report
Can and Can't Do
It carries real weight with insurers. It isn't the final word on fault.
1
Insurers lean on it
The first thing an adjuster reads
A clear report in your favor makes the other insurer much harder to argue with on who caused it.
2
It doesn't decide fault
The insurer does
The officer's view is one input. Insurers make their own liability decision, and courts have their own rules on how much a report counts.
3
Errors can be fixed — opinions rarely
Ask for a supplement
A wrong plate or insurer can usually be corrected. For a disputed opinion, ask to add your own statement with photos or witness details.
4
No report isn't fatal
Other evidence carries it
You can still file a claim. Photos, witnesses and camera footage matter more — and filing a report late is better than never.
⚠️ Report, photos and estimate — together
The report records who and how. Your photos and an independent repair estimate record what it cost. An adjuster weighs all three — our guide to accidents that weren't your fault shows where each one fits.

Document the damage while you wait for the report.

Common
Questions
Do I need a police report after a car accident?
If anyone was injured, call 911 from the scene — many states, including California, require injury crashes to be reported to police. For minor crashes with no injuries, requirements vary by state and police may not respond, but filing a report online or at the station is usually worth doing, because it is the first official record of what happened.
How long do I have to file a police report after an accident?
It depends on the state and the department. Some require injury crashes to be reported within 24 hours, and a report filed promptly is more useful than one filed weeks later. If you didn't report at the scene, contact the local police or highway patrol as soon as you can to ask how to file.
How do I get a copy of my accident report?
Request it from the agency that responded — city police, the county sheriff or the state highway patrol. Most accept requests online, in person or by mail, and drivers and owners involved in the crash can usually obtain a copy, sometimes for a small fee. Reports typically take a week or more to be finalized, so have the report number ready.
Does the police report decide who was at fault?
No. The officer's opinion carries real weight with insurers, but each insurer makes its own liability decision, and courts have their own rules about how much weight a report gets. Photos, witness statements and camera footage can support or challenge what the report says.
What if the police report is wrong?
Factual errors, such as a wrong plate number, insurer or name, can usually be corrected by contacting the reporting agency. Officers rarely change their opinion about the cause, but you can often ask to add a supplemental statement with photos or witness details. Raise errors as soon as you notice them.
Do I need to report the accident to the DMV too?
Often, yes — it is separate from the police report. In California, an SR-1 report is due to the DMV within 10 days if anyone was injured or killed or if property damage exceeded $1,000, regardless of who was at fault or whether police responded.
Can I file an insurance claim without a police report?
Yes. A police report is helpful but not required to open a claim. Without one, other evidence carries more weight: photos of both vehicles and the scene, the other driver's details, witness contact information, any camera footage, and an independent repair estimate.
