The California Highway Patrol saw Kardashian driving down the 101 Freeway and stopped her because the plate was missing, reported Aceshowbiz.
The 30-year-old apparently kept the plates in her glove compartment and got away without being ticketed. She has had the luxurious car for a couple of weeks now.
The "Keeping Up With The Karadashians" star rolled up the new Dash store on Melrose in Hollywood recently in her new Rolls-Royce with boyfriend Kanye West by her side.
They went in the store after being mobbed by fans and paparazzi.
