A vehicle struck a security barrier on Fort Hood Tuesday morning, causing damage to both the vehicle and the structure and backing up traffic nearby.

According to a Fort Hood official, the vehicle approached the West Fort Hood gate at Clarke Road and Highway 190 South. The official did not immediately say who was operating the vehicle or why the vehicle was there, but he said "a miscommunication" happened between the driver and the gate guards -- causing the guards to deploy the barrier system that prevents vehicles from entering the world's most sprawling military installation.

The Fort Hood official said no injuries were reported. But, as a precaution, the driver was transported to Carl R. Darnall Army Medical Center to be evaluated.

Repairs to the barrier were completed by 7:30 a.m., but there was a temporary traffic backup until then. Traffic flow has since returned to normal.

Following phone calls, Fort Hood officials declined to offer any specific details about the driver or why the vehicle was attempting to get on post. In an emailed response, an official said the matter was being investigated Tuesday by the Directorate of Emergency Services.
