Most of the countries using miles per hour in the Pacific are in free association with the United States, which uses miles per hour. Due to the unique relation between these Pacific countries and the US, these countries derive the majority of their laws and road signs from the US. In short, they use 5 mph increments.JRN wrote: ↑Thu Jun 10, 2021 14:00Sorry what I meant was, other countries either use 10 km/h (~6 mph) increments, whilst the only other major country to use miles, the USA, uses 5 mph increments.Chris Bertram wrote: ↑Thu Jun 10, 2021 10:02Well, how many countries are still using mph at all? It's not such an issue where km/h are in use, as 10km/h is a smaller increment.
However a few other countries in the world use miles, Belize, Liberia and a few islands in the Carribean and Pacific, not sure if they use 5's though, countries influenced by America might.
As for the Caribbean islands, Anguilla and Monserrat use 10 mph increments, like the motherland. As for the other British overseas territories, they use 5 mph increments, with Bermuda also using both mph and km/h. Other Caribbean countries using mph were apart of the British West Indies, which is why they still use miles per hour and imperial gallons. Most use 5 mph increments due to US roadsigns being cheaper to import and the design norm in the Western Hemisphere. Belize also uses 5 mph increments once again due to US influence.
Aside from the lesson, is there any reason why we can't implement a 25 mph limit?
