Can I Rent A Car Without Insurance? 
Mark has given you a good answer which I would like to expand upon . Always share where you are going with your agent.Even if your policy extends to temporary use of a substitute vehicles , -LRB- which many policies do -RRB- . Be sure your agent understands where you expect to rent . Most auto policies in the US have geographical limitations too . Note most policies in the US extend use and coverage into Canada . Note it does not say US , Canada andMexico Thereasonit does not , is that you have to buy your legal liability coverage from a Mexicaninsurereither as you cross theborder or from agents who can legallysellthat coverage . If you are traveling and renting a car in multiple countries I suggest you ask your agent for more information on umbrella policies which typically have some coverage world wide , but even then be sure your agent hasreviewedyouritinerary before you land in another country.IF you get there and have an umbrella , it is best to at least buy the minimum coverage available in the country while you visit . Keep this advice : do n't ignore the locals .
