Auto Insurance question that is not my car?

My uncle just bought a 2010 Civic Coupe and HES let me go, can I add to my uncle the car on my insurance if it is not my car

thats not how it works, it needs to add you to be, but unless you live in one house, and it can drive his car, which probably has a comprehensive coverage, your uncle’s deal with it in his car after all, and not your responsibility, is the right way to do this, you into their policy in this way, you’re a driver named on the insurance contract as well.
