Police are inquiring as to whether a crime may be behind the incident, which left a crack on the car’s windscreen, local media Horsens Folkeblad reports.
Recent years have seen a string of incidents in which rocks have been thrown from motorway bridges into oncoming traffic. Once such act resulted in the death of a German woman who was a passenger in a vehicle which was hit. The case, which is being treated as murder, is yet to be solved.
The latest episode occurred when a woman from Svendborg on the island of Funen drove under a bridge on the Danish motorway at around 9:40am on Thursday.
Her car received a crack to the windscreen around three centimetres in length, but the woman was able to keep the vehicle and control and continue driving. She reported the incident shortly afterwards, inspector Lars Peter Madsen of South East Jutland Police confirmed to Horsens Folkeblad.
“We are taking this quite seriously because it is potentially very dangerous to be hit by a rock on the motorway,” Madsen said.
The inspector added he hoped for potential witnesses who may have seen something on the bridge, which is on the Bredalsvej road near Hedensted, to come forward.
On Wednesday this week, a similar incident saw a car hit by an unidentified object on the E45 motorway in South Jutland, close to the exit for Christiansfeld.
In that instance, the car’s sunroof was smashed but nobody was injured.
Police subsequently closed the motorway in order to search an extended area, but this did not turn up any further information.
