Grandparents can add grandchildren to their car insurance policy if they have a Hyundai Venue. In most cases, the car will stay covered under the terms of permissive use if a grandchild borrows the car. It is possible to add someone who doesn't live with you to your car insurance policy, depending on your insurance company's policies. Typically, insurance companies allow you to add immediate family members or someone who regularly drives your vehicle. However, this could change depending on a few factors. To add a grandchild to a car insurance policy, it is best to contact the insurance company directly to confirm their policies and procedures for adding a non-resident driver to the policy.
