# SACrashDetectionEvent

Describes the information about a vehicular crash.

```
class SACrashDetectionEvent
```

## Overview

When a vehicular crash occurs, SafetyKit calls your delegate’s [`crashDetectionManager(_:didDetect:)`](/documentation/SafetyKit/SACrashDetectionDelegate/crashDetectionManager(_:didDetect:)) method with an [`SACrashDetectionEvent`](/documentation/SafetyKit/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.

## Topics

### Determining the event type

[`Response`](/documentation/SafetyKit/SACrashDetectionEvent/Response-swift.enum)

An enumeration that defines possible emergency responses to a Crash Detection event.

[`date`](/documentation/SafetyKit/SACrashDetectionEvent/date)

The date and time the crash occurred.

[`location`](/documentation/SafetyKit/SACrashDetectionEvent/location)

The longitude and latitude where the crash detection occurred.

[`response`](/documentation/SafetyKit/SACrashDetectionEvent/response-swift.property)

An indication of whether the system attempted to call an Emergency SOS provider.
