Buy Car Insurance

Can I buy a car without Insurance?
Im 19 and planning on buying a car soon and I wanted to know if i need Car Insurance to buy a car or will they provide me with one when I buy the car. Also the car will be in my mother’s name she has her own car but also doesn’t have any Insurance.
It is hard to say,call you local agent or do some research yourself by using seach engine,you should get the idea.
