A off-duty Louisiana State Police trooper was arrested Sunday morning after a single-vehicle crash on Interstate 55 at the Interstate 12 interchange in Tangipahoa Parish.

The investigation revealed that a 2013 Chevrolet Cruze, driven by 27-year-old Isaiah Gilbert of Hammond, was traveling southbound on Interstate 55 when it traveled off the roadway to the left and impacted a sign, said Trooper William Huggins.

As a result of the crash investigation, Gilbert was arrested and charged with driving while intoxicated, first offense, and careless operation.

Huggins said Gilbert, who was off-duty and in his personal vehicle at the time of the crash, is assigned to the patrol section of the Louisiana State Police.

Gilbert has been placed on administrative leave, and all law enforcement property was recovered pending the conclusion of the criminal and administrative investigation.  He has been employed with the Louisiana State Police since 2021.
