Police say the accident happened just after 7 a.m. Saturday morning when troopers were notified of a motor vehicle crash with injury on Interstate 10.
The crash involved Lieutenant Robert Hodges with the Louisiana State Police.
Officials say Lt. Hodges was assigned to patrol during the holiday weekend and was parked on the right shoulder of I-10 west at mile post 218.5 conducting speed enforcement.
Investigators say as Lt. Hodges was exiting the driver's side door of the fully marked LSP Chevrolet Tahoe and was standing between the door and the frame of the Tahoe,a 2003 Toyota Corolla, driven by 20-year-old Kirby McCaskill of Donaldsonville, was traveling in the left lane approaching Lt. Hodges' location.
Traffic in front of McCaskill began to slow down, causing McCaskill to swerve into the right lane and into the right shoulder, striking Lt. Hodges and the driver's door of the Tahoe.
Lt. Hodges sustained moderate injuries and was transported to a local hospital for treatment.
Police say McCaskill voluntarily submitted to a breath test in which no detectable alcohol was found.
Following too close and speed are considered factors of the crash and charges are pending.
