Renting a Car in Mexico

Mandatory liability insurance will be included in the rental. If you also pay for a collision damage waiver, then the implications of getting in a wreck are minimal.

I mean, don't drive drunk and kill someone. That would have implications.

I'll add that the corrupt Mexican police prey on American drivers. Be prepared to be pulled over multiple times and shown a placard that shows that you are speeding even though no signs exist showing the speed limit on the placard. I'm not sure about PV but it is prevalent in Cancun.

I love Mexico but will never rent a car there again.

I never travel in a foreign country with my passport. It's locked away in the safe where I stay. We'll carry a copy of our passport in those circumstances. Once we arrive at a destination the passport is locked away.
