How Much Extra Is Business Car Insurance? 
This depends upon what you mean by `` Business Car Insurance . '' If you are asking about insuring an automobile with a business auto policy , those are typically more expensive than a personal auto policy . If you are asking about insuring a company car , then that should be handled by the business providing you the automobile . The company should look into endorsements covering other drivers , in case your family members living in the house use your company car . If you are asking how much it costs to insure a company car on your personal auto policy this is not really an option because you do not have a valid insurable interest in the car . What I mean by this is the company owns the car and is getting a benefit from letting you use it , so your only interest is not paying for a car , which is not an insurable interest on your part . I hope this helps !
