The second driver, who stood in front of the first driver to protect him, was also punched in the face, which knocked his glasses into the gutter, the court heard.
Torlesse walked off but was found by police a short time later.
The court heard that Torlesse told police that the first driver "got lippy" with him, so he "kicked him the a***", punched and kneed him.
The "second guy started picking on him" so he punched him in the head too, the court heard.
The first driver's injuries included a 2.5cm cut on the back of his head and bruising on his upper thigh, and the second driver suffered tenderness to his head and a bloodshot eye.
Torlesse was remanded on bail for sentencing on April 26.
