It is important to note that some insurance companies may not offer coverage to individuals who do not own the vehicle they are driving. If this is the case, your son may need to find an insurance company that is willing to provide coverage for him.
It is also important to be aware of the legal requirements for insurance in your state. In some states, it is illegal to drive a vehicle without insurance, regardless of who owns the vehicle. If your son is caught driving a vehicle without insurance, he could face fines, penalties, and even the loss of his driver's license.
If you have any questions about insuring a car that your son does not own, it is best to contact your insurance company or an independent insurance agent. They will be able to provide you with the most up-to-date information on the laws and regulations that apply to your son's situation.
