Reporting unsafe driving

Has anyone reported to the police department for unsafe/illegal driving? Tesla this morning was using the middle turning lane to pass drivers on the left INCLUDING a school bus that was picking up children down on east main heading towards meridian. I have their license plate number but have never reported before. I was irritated when she passed me but pissed when she passed the bus full of kids as they were getting situated. Or should I just contact the school district with the information?
