There are two primary reasons for having Mexican automobile insurance when driving in Mexico:

U.S. auto insurance is not recognized in Mexico! If your U.S. insurance agent tells you that your U.S. insurance will cover you in Mexico, it is simply a sure sign that the agent is out of touch with the reality of the situation.

Under Mexican law the police detain all parties in an accident until guilt has been determined, and some sort of financial settlement reached. This law applies equally to Mexican citizens and foreigners. An insurance policy will demonstrate financial responsibility, even if guilty, and will allow you continue on your way (if possible). Just to protect yourself from the hassle of dealing with the Policia and their jail, it's a good idea to have at least basic liability coverage. (Jail is a common detainment area while accident issues are being resolved.)

It's easy to get Mexican vehicle insurance at most border areas. The insurance is rather expensive when purchased on a daily basis (about $5-$8US per day for an auto). There are plans other than the daily ones available at the border - ask about them. I believe that what they do at the border is charge you for the most expensive car on their list, unless you clearly negotiate the appropriate rate.

If you will be traveling for two weeks or more, it probably pays to get an annual policy. Request a policy which covers the smallest region within which you'll be traveling.

What I do is purchase annual insurance through an agency in Los Angeles. The coverage is good for all of Baja California and the northern states of mainland Mexico. This Mexican insurance is written through:

I find driving in Mexico to not be a problem once I get back into the swing of driving as the Mexicans do:

BE ALERT AND SLIGHTLY AGGRESSIVE.

Especially, watch for obscure or missing (!) stop signs - the missing ones are spotted by the presence of a matching, and present, stop sign on the diagonal corner (or writing on the street). Don't expect other drivers to come to a complete stop at these stop signs (or even a partial stop!).
