After a minor fender bender, a lot of drivers swap information, assess the small dent, and go their separate ways figuring that's the end of it. For a lot of accidents in a lot of states, that's fine. For others, skipping the report means a suspended license, a voided insurance claim, or legal exposure you didn't see coming. It's one of those things where the cost of getting it wrong is pretty steep. If you're still figuring out the on-scene side, what to do after a car accident covers the first 30 minutes step by step.
Here's how the whole system actually works.
Two reports, two different systems
This is the part most people don't know. There are two separate types of accident reports, and they're not the same thing:
The police report
Filed by law enforcement at the scene. When officers respond, they write an official report documenting what happened, who was involved, and their assessment of the situation. You request a copy from the responding agency, get a report number, and that's what your insurance company asks for. In minor accidents with no injuries and low damage, police may not respond at all — or they might respond but not write a full report. That's normal.
The DMV report (SR-1, FR-300, or equivalent by state)
This is the one people forget about. Most states require you to file a separate report directly with the DMV when an accident meets certain criteria — regardless of whether police showed up. This is your legal obligation. The police don't handle it for you.
What triggers a DMV reporting requirement?
Most states require you to file when the accident involves any injury, any fatality, or property damage above a specified dollar threshold. The property damage threshold is where it gets interesting — it varies a lot.
Based on current state data, thresholds range from $250 in Washington D.C. on the low end up to $3,000 in Hawaii and Vermont. Most states land somewhere between $1,000 and $2,000. If the total damage across all vehicles clears your state's number, you're required to report.
Time limits
Deadlines vary significantly by state — there is no single national standard. California and New York require filing within 10 days. Some states allow up to 30 days. Others require notice within 24 hours when there are injuries. A handful allow considerably longer windows in limited circumstances. Check your specific state's DMV website for the current deadline; these rules do change, and you want the version that's actually in effect today, not something posted three years ago.
What happens if you don't report?
Consequences vary but can include a license suspension, fines, and complications with your insurance claim. A missing report can apparently be used as evidence that the accident wasn't serious enough to document — which makes things awkward if the other driver later claims injuries you weren't aware of at the scene. That happens more than you'd think, particularly in low-speed rear-end collisions where whiplash doesn't always show up immediately.
When police don't respond
In a lot of jurisdictions, police won't come out for an accident where nobody's hurt and both cars can drive away. Especially in busy urban areas. In those cases, it's on you to document the scene yourself, exchange information, and — if damage is over your state's threshold — file the DMV report within the required window. Some states have online self-reporting systems. Others still want a paper form. Your state's DMV website has whatever format they use. One other thing to handle at the scene: if you need a tow, predatory tow trucks show up uninvited at a lot of accidents — the tow truck scams guide explains your rights before someone hooks up your car without asking.
Should you report even if you're technically not required to?
Generally, yes. Filing creates a record of what happened, when, and how it was documented. If the other driver later claims injuries that weren't apparent at the scene, having a contemporaneous report on file is a lot better than not having one. Your insurance company will appreciate the documentation too.
The honest reality: most people don't know their state's reporting threshold, let alone whether they're over or under it after an accident. A reference card in the glovebox with your state's rules takes care of that problem before it ever comes up. The full list of what should be in your glovebox is worth ten minutes to set up.
If someone was injured
If anyone was hurt — passengers, the other driver, a pedestrian, anyone — the reporting requirements are stricter in every state. With injuries, filing is almost always mandatory regardless of damage amounts, and the timeline is often tighter. Always call 911 when there's any possibility of injury. The responding officers will document everything, and that report becomes essential to everything that follows.
