The first maximum speed law for Mexico was created in 1903 by then president Porfirio Díaz.
[1] 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: No Mexican highway allows going beyond 110 km/h,[2] but the speed limit is enforced generally above 130 km/h (81 mph) only.
