Your liability, comprehensive (other than collision) and collision coverage most likely will protect you if you are traveling in the United States, its Territories and possession or Canada. Coverage will not follow you anywhere else in the world. Our Agency recommendation is for you to purchase coverage offered by the Rental Car Company, as all Rental Companies vary in their contracts in what you may be responsible to pay if there is a loss to their vehicle. Also, your personal auto coverage will not follow to a commercial vehicle.
