Topic overview

This chapter covers what to do immediately after a crash — stopping safely, helping the injured, calling 911, and exchanging information — plus the rules for when a driver is legally required to file a crash report.

The most-tested facts are the timing and thresholds: drivers generally have 30 minutes to report a crash, and a report is mandatory once damage, injury, or death crosses specific thresholds, regardless of who was at fault.

A common mistake is confusing the duty to report a crash with the Safety Responsibility Law and Financial Responsibility Law, which are separate insurance-related requirements that can suspend a license even after a report is properly filed.

How soon must a driver report a crash to police?

Generally within 30 minutes of the crash. Many towns and cities also require notifying local police directly if the crash happens within their limits, or the county sheriff or state police in rural areas.

What happens if I leave the scene of a crash that caused injury or death?

It can lead to criminal charges, and the Secretary of State's office is required to revoke the driver's license — this is separate from, and in addition to, any penalty for the crash itself.

What's the difference between the duty to report a crash and the Financial Responsibility Law?

Reporting a crash is about notifying authorities that it happened. The Financial Responsibility Law is a separate insurance requirement — it applies when a driver is uninsured and at fault, or has repeated insurance violations, and can suspend a license independently of whether the crash was reported.
