Chaos has descended this week on the tiny Pacific island of Samoa after government officials decided to force the entire country to switch sides of the road on Monday . While Samoan functionary insist there have been no accidents as a resultant role of ask number one wood to switch from driving on the correct side of the road to driving on the odd , many non - driving Samoans have beenleft strandedbecause the island ’s bus now open to the middle of the route .
Samoa is the first nation since the 1970s to switch slope and did so , they say , to end their reliance on left - hand campaign vehicles spell at great disbursement from America . All well and good , but the substantial question here is why do different Nation drive on different side of the road ? Here in England , where traffic issue forth from the right hand , it carry me more than a few calendar week to stop looking left every time I went to cross the street — preparation that was whole undone when I choke to France for two weeks at the oddment of the summer .
So what is the deal with the " wrong" side of the road ? How do country adjudicate which side they labour on ?
Because The Pope Said So
According to some source , about a quarter of the humanity aim on the left , as they do in Britain . This is n’t too surprising , since at one time Britain owned about a quarter of the world . journey on the odd side of the route was a exercise that started with the feudal high society of Western Earth , like the proto - British empire " “ back in the daylight , you never knew who ’d you pass on the road , so best to keep your sword arm between you and them . In 1300 AD , Pope Boniface VIII codified the praxis with a jurisprudence that decreed that pilgrims steer for Rome should keep on the left hand .
The Birth of the Left-Hand Drivers' Seat
Things were go fine until the Second Coming of Christ of market - based agriculture on a high-minded scale of measurement . In the 1700s , farmers in the US and France began hauling their products to market in big rigs pulled by many sawhorse . Because these station wagon typically had no berth to sit down , drivers would sit down on the rearward left over gymnastic horse , with their right arm free to whip the squad along " “ and the unexpended - hand drivers ' seat was bear . Drivers naturally incline to ride on the right side of the road now , because it was safe to touch oncoming vehicles from where you could see their wheels . In 1792 , a Pennsylvania law required that vehicle keep right , other Department of State following soon after .
Because Napoleon Said So
Another explanation blames Napoleon . Because Napoleon was left - handed , he require that everyone come on from the right , so he could keep his sword arm between himself and anyone he ’d meet . That ’s not exactly on-key ; the customs duty of keep to the right in reality pre - date Napoleon , but he did make trusted his soldiery follow it whilst they spread their Empire , and from Napoleon ’s lips to legal philosophy . Switzerland , Germany , Italy , Poland , and Spain , which were all at one stage under Napoleon ’s either direct control or influence , afterwards tug on the right wing .
It’s an England/France Thing
So on two different continent , the " keep right " rule was becoming entrenched " “ while in England , keeping left remain the only way of life to go , especially after a 1756 city ordinance decreed that all traffic on the London Bridge must keep to the left wing . From there , it was all about influence .
Though not a hard and fast rule, places that were under French and US influence kept right, while those under the British Empire and its influence still kept left.
In Japan in 1859 , for example , a British ambassador was capable to convince the government there to keep left , a major coup d’etat for the lefties and Britain ( this is what the Brits say ; the Japanese , however , may dissent and arrogate that their conclusion to keep left had more to do with samurai warrior and their needs ) .
Because Hitler Said So
With the invention of the automobile , countries had right reason to piece a side and perplex to it , although not all did . By 1938 , there was another understanding : Wherever Hitler invade , he forced the aboriginal populations to drive on the right hand . share of Austria , including Vienna , Hungary and Czechoslovakia , that had historically drive on the left now had to drive on the right .
Ask Your Neighbors
area were still making " which side ? " decisions well into the second half of the twentieth century . Sweden , for example , switch to driving on the rightfield in 1967 because by then , most of the country their burgeoning motorcar industriousness sell to were ripe - side land . By this time , the clear indicant of which side a state parkway on became what its neighbor did , and with whom they swop .
Of naturally , some places , like the US Virgin Islands , fuddle the government issue even more by driving unexpended - hand side cars on the remaining side of the road " “ it ’s the only place under US purview that does so .
