# SACrashDetectionEvent

Describes the information about a vehicular crash.

## Declaration

```swift
class SACrashDetectionEvent
```

## Overview

Overview When a vehicular crash occurs, SafetyKit calls your delegate’s crashDetectionManager(_:didDetect:) method with an SACrashDetectionEvent object. Inspect this object to determine information about the crash, including the date and time, location, and if the system attempted to contact emergency services.
