The current primary Louisiana State Police patrol vehicle is the Chevrolet Tahoe.
 The agency began a conversion to the Tahoe in 2012.
 Previously, the agency used the Ford Crown Victoria "Police Interceptor."
This vehicle was the main patrol vehicle used by the agency from 1997 to 2011, when it replaced the Chevrolet Caprice in 1996, and when the Crown Victoria was discontinued in 2011.
The vehicle's markings include "State Trooper" written on each front quarter panel, a state badge on the center of each front door, the words "Louisiana State Police" written above and below the door badge, and the words "State Police" written on the trunk.
Note that the markings on the Tahoe include a slight variation to the previously used designs.
 In 2012 all markings were re-designed.
 The door badge has been redesigned from a light blue to a darker blue.
Also the badge state seal in center was updated to reflect a 2008 change showing a more angular "Pelican in Her Piety" state seal done in white.
It is completely different from the prior one used from 1964 to 2012 except in dimension.
The red "LSP" lettering was also upgraded to a more reflective prismatic shade of ruby red, and each letter now has a small dark blue border around it.
An "ACE" insignia, consisting of a blue State of Louisiana with a red lightning bolt, is awarded to troopers who recover five or more stolen vehicles within a year.
Since approximately 2001, a majority of the marked patrol vehicles utilized by this agency have been equipped with onboard video cameras.
Other 'marked' patrol vehicles currently used include Harley-Davidson motorcycles, the Chevrolet Camaro, the Chevrolet Tahoe and Suburban, with incidental examples fielded since 2013 of the Ford Taurus Interceptor, Ford Explorer Police and Caprice PPV.
Announced on January 31, 2018, beginning in the succeeding month [February], newer models of the Dodge Charger were introduced.
The latter included "less visible, semi-marked and unmarked" vehicles to "[...]combat aggressive, impaired, and distracted driving."
