Do I need to buy Mexico Auto Insurance even if my domestic coverage has a Mexico coverage?
Many US insurance companies in the Border States with Mexico extend coverage into Mexico for a certain number of miles from the border. Be aware that this coverage is restricted to the number of times you cross into Mexico, and only covers damages to your vehicle not third party liability. So YES, even if you have an endorsement for extended coverage to Mexico, you should buy third party liability, the minimum coverage required by authorities in case of an accident. It is important that you purchase your Mexican insurance prior to entering Mexico.
