A crash involving a FBI agent completely shut down the outer loop of Interstate 485 near Steele Creek Road Thursday afternoon.

According to North Carolina Highway Patrol, an on-duty FBI agent driving a black SUV was parked on the left shoulder off the highway when a pickup truck veered off the road and crashed into the SUV.

Three people suffered potentially life-threatening injuries and the driver of the pickup truck was airlifted to Carolinas Medical Center—Main.

Witnesses say the woman driver of the truck that struck the SUV was speeding.

Highway Patrol directed traffic off of I-485 at the exit ahead of Steele Creek Road while crews worked to clear the scene.

As the speed of a car increases, the chances of being in a dangerous, potentially fatal crash increase exponentially.  In fact, a driver going 35 miles per hour is two times more likely to kill someone than if they were driving 30 miles per hour or less.  Long story short, speed is no stranger to motor-vehicle crashes, and obeying the speed limit saves lives.  If you are involved in a serious accident, call 704-499-9000 or 877-374-5999 toll-free to contact the trusted Accident Attorneys of Reeves, Aiken, and Hightower.  Our attorneys are will help you along each and every step in your path to recovery.
