just wanted to know something

my insurance is coming up soon, gotta put out like a grand or so to pay for it, but i just wanted to know, if i sell the car, and buy a new car, does the insurance move over to the new car?

so lets say i pay the insurance, but a week later i sell the car, and buy a new car, does it mean i have to buy new insurance for the new car, which means i wasted 1.5k on insuring the other car?

or what? yea i know its probably a stupid questions, as my dad called for the insurance, as its under his name, so yeah.
