Mexican auto insurance is very easy to obtain and is
sold in varying increments. The insurance can be purchased as
liability only, or you can purchase the full liability, collision and comp
options. Either way, liability for every minute you are in Mexico is
the law!
U.S. insurance for all of your vehicles, including
cars, boats and trailers of any kind, is very limited south of the border,
at best. Additionally it is against the law to drive in Mexico
without liability insurance. In Mexico, you are guilty until proven
innocent, therefore if you should have an accident (even a fender-bender),
it is automatically your fault, until you prove otherwise. As a
result, you must show that you can pay for any damages (including
hospitalization and other costs associated with bodily injury) or you will
be detained (see legal assistance option below).
