Mexico City is not really a driver friendly city, especially for tourists, and more so for those who cannot read Spanish, as almost all signs on the road and freeways are in Spanish.
Wearing seatbelts while driving is required by law – and you never know what you may come across on the road, including bribe-hungry police sergeants just lurking in search of a casual, unsuspecting foreign driver.
Be sure to keep a map handy as multiple streets may often have quite similar or even the same names, and it is more helpful to know which neighborhood you are heading to rather than having a specific street or business name.
Generally, street parking is not available in the city, and time should not be wasted searching for it. Paid parking is available at most upscale restaurants, malls and parks.
