Two cars drove into each other on the Autobahn 5 near the Taunusblick service area on Friday night.
The cause of the accident at Eschborn is currently unclear, said a police spokesman on Friday.
A driver was slightly injured and had to be taken to the hospital, as the fire department reported on Twitter.
The accident left a huge field of rubble on vehicle parts, which is why the motorway in the direction of Kassel was completely closed for an hour.
