A 26-year-old woman suffered severe injuries in a head-on collision with a truck on District Road 25, between Kaiserslautern-Einsiedlerhof and Rodenbach, according to Westpfalz police.

The accident occurred around 7 a.m., leading to significant emergency response and closing the road to traffic for several hours.

The woman was driving her Mazda 3 towards Einsiedlerhof when, for reasons yet to be determined, she veered into oncoming traffic, resulting in a frontal collision with a truck, police said. The impact was so forceful that her vehicle was thrown into the fence of a nearby U.S. military installation, causing the driver to sustain critical injuries.

She was transported to a hospital by ambulance and an emergency helicopter was deployed to the scene, according to police.

The cause of the accident remains under investigation, Westpfalz police said.
