Is this ticket from a red light camera, or was she stopped by a real live police officer?
If the ticket was from a camera, no points are issued, it will not appear on her driving record, and it will not affect her insurance rates.
If it was from an officer, then that’s different. Points are issued, it will go on her insurance record, and it probably will affect her insurance rates.
Whatever the case, I like to walk on 16th Street. Please ask your sister to kindly refrain from running red lights when she comes to visit you.
