Should Our 18 Year Old Son Have His Own Car Insurance Policy? 
I love CPA 's . They give great accounting advice and some of them even know other things . But the `` minimum limits '' advice defies his training in some important ways . What your son lacks in `` assets '' he more than makes up for in terms of `` potential '' . What I mean here is that he may not have it now , but due to his young age , he 'll have a long time to earn and pay . Even though he is only 18 does not mean that he can not be responsible for an injury or death , or damage to property , and be subjected to an order of the court to garnishee his wage to make reimbursement to those who were injured , killed , or had property damaged . Now , should have have his own insurance ? Assuming he owns the car , he probably needs his own insurance . Staying in the household under household coverage is also OK but some insurers concern themselves with the owner of the car being different than the insured on the policy so proceed with caution when the vehicle is not actually owned by the policyholder . As a practical matter , the discounts that you might enjoy are lost to the child in many cases when they have their own policy . Some companies will extend multi-policy discounts to children of the policy owner . Some discounts do n't come through this connection , however . I like kids learning the responsibility of maintaining their own insurance . It gets the loss off the parents record , for one . Parents can help subsidize the cost if they want and help provide this as a reward for good outcomes on something else . All things said and done , I like responsible children on their own policies but deal with young drivers both on and off the parents policies so it comes down to personal preference and whether you are dealing with issues that poison the whole policy because of the young driver , or not , in many cases .
