Driving Around Without License Plates

So far I haven't gotten plates yet for my car. I've gotten pulled over my first time on 42nd Street by Noelridge Pool. The cop just asked to see the title of the car and my insurance and of course my driver's license. She gave me a warning because she really didn't know if she could give me a ticket or not for not having a temporary license plate. She told me that I should probably call my insurance and ask them what to do..I never did. I got pulled over last Saturday too when I was in Marion. I was on my way to the mall from a christian hangout place called Catch419 and that's when I got pulled over. The cop flashed his lights and made me pull over into Village Inn and he came up to my door and told me he pulled me over for my plates. I gave him my insurance and the title to the car and he checked it out. He asked me where I got the car and I told him from a lady who lives out on county home road, it was an individual sale. He told me then that you can only get temporary license plates from a car dealership and that I couldn't get them because I bought it individually. I know that I have a month to get plates after I bought the car and it had only been roughly two weeks so I knew that I still had time to get plates. I'm getting the plates for the car on friday because that's when I get paid and thats when I'll be able to get them. I'm getting tired of always getting pulled over. It's a major waste of time and I know that as soon as I have plates on the car i'll be a happy man.
