American auto insurance policies are good anywhere in the United
States, Mexico,
or Canada. Some
policies differ a bit on coverage in certain states, however, and liability
laws in Mexico
tend to be a little different than those in the US.
If you’re traveling overseas or to South America, then
you might want to look into getting insurance in the country that you’ve
traveled to for the duration of your visit since insurance laws vary from
country to country. When traveling out of the country, is usually best to rent
a car and pay the additional amount for insurance through the rental agency…
that way you know that the policy you have is valid in the area you’re in, and
should the worst come to pass the place that you rented the car from will take
care of all of the details.
