Bad Rodach (dpa / lby) - A paper cup carelessly thrown out of the car window triggered a traffic accident in Upper Franconia.

A co-driver threw away his coffee mug on State Road 2205 near Bad Rodach (Coburg district), the police said on Monday.

As a result, an 18-year-old driving behind it was frightened on Sunday, dodged the cup and hit a delineator.

The police used the license plate to identify the driver and front passenger of the other car.

Both are now being investigated.
