Transport and infrastructure in Tonga

Road traffic

The network of roads and highways has a total length of 680 km. For each of the country's 105,697 inhabitants, this corresponds to 6.43 meters. This puts Tonga in 87th place in the global ranking. However, the country's size and population density of around 141 inhabitants per km² must also be taken into account. Countries with fewer inhabitants on the same or even larger area naturally achieve quite different values here and have to connect remote areas to the transport network despite a smaller population.

With an average of 15 traffic fatalities per year (2012 - 2019), road traffic in Tonga is considered reasonably safe. This corresponds to around 4.3 accident fatalities per 15.1 inhabitants per year. By comparison, this figure is 5.9 in the European Union as a whole and 17.1 worldwide.

In Tonga, traffic drives on the right-hand side of the road, i.e. people drive in the right-hand lane and overtake on the left. Oncoming traffic comes toward you on the left side. Here you can also find an overview of all countries with left-hand traffic.
