Discription of Events: On 8/23/2024, while driving from West Point to Starkville on Highway 82, I encountered a black Ford F-150 truck with extended side mirrors and a B-10 license plate. The driver of this truck displayed aggressive behavior by preventing me from merging into the exit lane, driving parallel at the same speed, and brake-checking me, forcing me to slam on my brakes. The truck then alternated between speeding up to 80 mph and slowing down to block my path, creating a hazardous situation for myself and other drivers.This sudden maneuver caused a potential risk of collision, especially with multiple vehicles behind me and others passing in the fast lane. The truck continued its aggressive behavior by alternating between speeding up to approximately 80 mph and abruptly slowing down, preventing me from passing. This pattern of dangerous driving persisted all the way to the Starkville exit. Once on Highway 82 towards Starkville, the truck moved into the fast lane and began tailgating other vehicles in an intimidating manner. The truck eventually exited in Starkville, taking the exit towards Clayton Village on Old Highway 82 East.
