The first maximum speed law for Mexico was created in 1903 by then president Porfirio Díaz. It established a maximum of 10 km/h (6 mph) for small and crowded streets, and 40 km/h (25 mph) elsewhere. Current speed limits are:
 
- 10 km/h (6 mph) in parking lots and residential areas
- 60 km/h (37 mph) in streets with no speed limit
- 60?80 km/h (37-50 mph) on urban arterial roads (ejes, calzadas, beltways and freeways)
- 80 km/h (50 mph) in avenues with no speed limit
- 70?90 km/h (43-56 mph) on rural two-lane roads
- 90 km/h (56 mph) on two-lane highways
- 90?100 km/h (56-62 mph) on major highways inside cities
- 100 km/h (62 mph) on major highways leaving or approaching towns or cities
- 110 km/h (68 mph) on major highways
 
No Mexican highway allows going up to 110 km/h, but speed limit is enforced generally above 130 km/h (81 mph) only.
