First, you should know that U.S. driver’s licenses are valid in Mexico and that Mexican law requires that only owners drive their vehicles, or that the owner be inside the vehicle. You will also need Mexican insurance for all vehicles, including rental vehicles. U.S. vehicle insurance is not valid.
Mexican liability insurance is recommended in the event your vehicle is involved in an accident. Driving under the influence of alcohol, using a mobile device while driving and driving through a yellow light are all illegal in Mexico.
If you drive your vehicle up to 25 km into Mexico, you must apply for a temporary vehicle import permit with Mexican Customs, BANJERCITO or at some Mexican Consulates in the United States. The permit requires a valid passport and a monetary deposit that will be returned to you upon leaving Mexico before the expiration of the permit. Failing to apply for a temporary vehicle import permit may lead to impoundment.
The U.S. Department of State recommends that if you have an emergency while driving, dial 911. If you are driving on a toll highway (cuota) or any other major highway, you should contact the Green Angels (Angeles Verdes). They provide a fleet of trucks with bilingual crews. You can call them at (01) (55) 5250-8221.
