Got a traffic ticket for ing in line?

I was entering the turnpike in PA, I rode on the outside lane, and then merged into the front to cut down on the amount of time i had to wait. Sure it is rude, and unfair to the other drivers that wait patiently, but is it illegal. I didnt swerve around other cars, I slowly waited for a break in traffic, made eye contact with the car that was next, got the wave, and merged in. Then i got pulled over and was told i was driving recklessly...the ticket states: "OTHER: defendant cut off other vehicles entering turnpike on-ramp". is this illegal. i've never heard of this. at any exit ive ever seen, there is a line of car trying to "cheat" by sneaking to the front of the line.
