Keep in mind that if you obtain your tourist card before crossing the border, you will still have to stop at the Mexican immigration office at the border to document your entry date and to have your tourist card stamped by immigration officials. Tourist cards are no longer available at Mexican Consulates.
For citizens of other countries view the INM's list of Countries and Regions That Require and Do Not Require a Visa To Travel to Mexico - but DO require an FMM.
Previously it was believed there was a tourist zone/72 hour exemption, but this was never actually part of Mexican immigration law according to federal delegate Rudolfo Figueroa from INM (Mexican Immigration).
It is important to note that in Baja, even though you may take your vehicle to the end of the peninsula without a vehicle permit (see vehicle importation regulations) you are required to have a tourist card (FMM) in order to travel anywhere in the state.

Great insurance for your motor trip to Mexico.
