Once, on a flight home from San Antonio, rode with a Bodily Injury Adjuster for a major U.S. (national) auto personal lines insurance company. We shared stories, and when I asked exactly what occurs when one of their U.S. policies has a claim in Mexico, he chuckled and said “nothing”! We are not allowed to cross into Mexico to work…period. When I asked how they adjusted the claim, he said they processed the claim once the insured got themselves, and their vehicle back to the U.S. Absolutely worthless, so know what you have. Most U.S. insurance companies possessing this endorsement, will advise you get additional 3rd party liability coverage for Mexico.
