We understand how important it is for crash detection to work when you need it the most. If an accident wasn’t detected, it could be due to one of the following reasons:

Note: Crash Detection and professional emergency dispatch services are available only within the United States.

1️⃣ Speed and Duration

The app is designed to detect accidents when your vehicle has been moving at 25 mph for at least 30 seconds before the collision.

If:

• You were driving at a lower speed, or

• The trip duration was too short

The system may not recognize the event as a crash.

2️⃣ How the Vehicle Stops After Impact

For a crash to be identified, the vehicle must come to a complete stop quickly after the impact.

If the stop:

• Was gradual, or

• Was not a full stop

It may not meet the detection criteria required by the system.

3️⃣ Phone and Connection Requirements

For crash detection and alerts to function properly, your phone must be:

• Turned on

• Set to “Always” allow Location Access

• Connected to a stable cellular network

These conditions allow the app to detect the crash and send alerts in real time.

4️⃣ Crash Detection Settings in the App

Please make sure the OtoZen app is properly set up to detect accidents.

You can verify this by going to:
OtoZen App → My Safety → Emergency Crash Response

5️⃣ Phone Placement While Driving

Keep your phone in a secure and stable position, such as a dashboard or windshield mount.

This helps the app accurately track motion and improves the chances of detecting a crash.

Important Note

Even when all the above conditions are met, there may be rare instances where a crash isn’t detected.

This can happen due to factors such as:

• Temporary network outages

• Limited GPS availability

• Sensor malfunctions on the phone

• Algorithm errors

• Crashes occurring in areas with poor or no wireless coverage
