As an insurance agent, you probably already know that personal auto insurance usually extends to car rental insurance. You may have even used this fact to help your clients save money when they go on vacation and rent cars. Many car rental companies offer added insurance to their vehicles. After all, many people rent cars not just for when they are on vacation or they may not own cars at all, which means they don't have any type of car insurance in the first place. However, for those who do have personal auto insurance, a basic policy should extend to a rental car they get.
