Can one person insure two cars?

Absolutely.

Many insurers have what are known as multi-car discounts.

One of the best ways to save money on insurance is to have what is known as a "blanket policy", which covers your home, autos, and other amenities such as boats, and personal watercraft, should you be fortunate enough to own them.

There is not limit of how many cars you can insure. You usually get a discount for multiple cars since technically you should have less chance of wrecking both since you cant drive both at the same time.

Yes, however if you have more than one driver, you need make make sure that they are also covered on your insurance.
