href='http:\/\/www.todayifoundout.com' title='Interesting Facts'>Today I found out<\/a> why some countries drive on the right and some countries drive on the left.<\/p>\n<p>The origin of this varies based on the time period and country, but primarily throughout history people used the \u201ckeep-left\u201d rule.\u00a0 It has only been very recently that the world has predominately switched to the \u201ckeep-right\u201d rule.<\/p>\n<p>The first real archaeological evidence of a keep-left or keep-right type rule for a road, originates in the Roman Empire, which shouldn\u2019t be surprising as they built a lot of massive, well trafficked roads spanning Europe and thus would have needed to establish certain rules governing how people were to interact on the roads. \u00a0\u00a0So which side did the Romans use?\u00a0 Archaeological evidence suggests it was common for the Romans to drive on the left side of the road.\u00a0 This was first discovered in 1998 where a Roman quarry in Swindon, England had grooves in the road going away from the quarry on the left side that were significantly deeper than those on the right, due to the added weight of the stone.\u00a0 \u00a0It is not precisely known why they would have chosen this side, but it is probably similar to one of the main reasons this practice continued into the middle ages.<\/p>\n<p>During the middle ages the roads weren\u2019t always very safe for travelers; meeting people coming the other way on the road was something best done defensively. \u00a0Historians then believe the keep-left rule was adopted because, on a horse, if you were right handed and you met some unsavory company on the road, you could draw your weapon, typically attached to your left side, with your right hand and bring it to bear quickly against the person who is going the opposite way of you on your right; all the while, controlling the reigns with your left hand.\u00a0 Then of course, if you happened to meet a friend on the road, you could more easily offer your right hand in greeting without needing to reach across your body when on horseback.\u00a0 People on horseback then also typically ruled the road, so everybody else followed suit.<\/p>\n<p>This keep-left rule was so common that, in 1300 AD, Pope Boniface VIII decreed that all pilgrims headed to Rome from wherever they were coming from should abide by the keep-left rule of the road along their journey.\u00a0 This then held across most of the Western World until the late 1700s.<\/p>\n<p>What ended up happening to force the switch in the 18<sup>th<\/sup> century were teamsters in the United States, who would drive large wagons with a team of horses, as the name implies.\u00a0 These wagons tended to dominate the road and force everybody else to abide by the rule of the road they were using.\u00a0 Very importantly, in many of those old, large American wagons, they did not include a seat on the wagon for the driver.\u00a0 Rather, the driver would typically sit on the rear left most horse, when the driver was right handed.\u00a0 This allowed them to easily drive a whole team of horses with a lash in their right hand.<\/p>\n<p>This then forced the issue of having oncoming traffic on your left as the drivers would want to make sure any part of their team or wagon didn\u2019t collide with oncoming traffic.\u00a0 When sitting on the rear left most horse, this was much easier to do when using a keep-right rule of the road.\u00a0 Just as important, if you wanted to pass a wagon in front of you, or at least see further down the road when you are sitting on the left side, it is much easier done if you are using the keep-right rule; this would give you much greater visibility of oncoming traffic when sitting on the left of your wagon.\u00a0 Gradually, this system spread so that by the late 18<sup>th<\/sup> century, the first laws in the United States were passed, starting in 1792 in Pennsylvania, where the rule of the road was now officially a keep-right rule.\u00a0 This quickly spread throughout the United States and Canada.<\/p>\n<p>So how did this spread through Europe?\u00a0 It started with France.\u00a0 The reasons why the French switched to a keep-right rule instead of the traditional keep-left rule aren\u2019t completely clear.\u00a0 Some say it is because the French Revolutionists didn\u2019t want anything to do with anything that had ever been Pope decreed.\u00a0 Others say it was because they didn\u2019t want to use the same rule of the road the English used.\u00a0 Still others say it was entirely Napoleon\u2019s doing.\u00a0 The reasons why he may have done this, if that is the case, are even murkier ground.\u00a0 Whatever the case, France switched to the keep-right system. \u00a0Napoleon then spread this system throughout the countries he conquered.\u00a0 Even after he was defeated, most of the countries he had conquered chose to continue with the keep-right system.\u00a0 The most important of these countries, as far as eventually further spreading the keep right system, was Germany.\u00a0 Fast forward to the 20<sup>th<\/sup> century and, as Germany conquered countries in Europe, they forced their keep-right system onto those countries.<\/p>\n<p>England never adopted this method primarily because massive wagons, as became common in the United States, didn\u2019t work well on narrow streets which were common in London and other English cities.\u00a0 England was also never conquered by Napoleon or later Germany.\u00a0 Thus, they kept the classical keep-left rule of the road that had endured for hundreds of years before.\u00a0 \u00a0By 1756, this was actually made an official law in Britain.\u00a0 As the British Empire expanded, this keep-left rule, as a law, spread throughout the world.\u00a0 This hasn\u2019t endured in most of the former British ruled countries, primarily thanks to Germany and the growing popularity of the keep-right system.\u00a0 There are still a few though, probably the largest of which, by population, is India.<\/p>\n<p>If you liked this article, you might also enjoy our new popular podcast, The BrainFood Show (<a

all water traffic should keep to the right when two sea craft pass one another going opposite directions.\u00a0 The reason for this was that historically the steering oar for ships was on the right hand side of the boat.\u00a0 Thus, by passing each other port to port (keep-right), they would protect the steering oars from colliding as would have been possible had they adopted a keep-left rule.<\/li>\n<li>In aircraft, the \u201crule of the road\u201d is keep-right when passing oncoming air traffic.\u00a0\u00a0 Interestingly, in dual-control airplanes, the captain always sits on the left side of the plane as you might expect, but in helicopters, the captain sits on the right hand side.<\/li>\n<li>Many early cars had the driver\u2019s seat in the center of the car rather than on one side or the other.\u00a0 Gradually, car manufactures began putting the seat on one side or the other.\u00a0 Some chose to put it on the side closest to the curb so that people could more easily avoid scraping buildings, curbs, etc.\u00a0 Other car manufactures would put it on the opposing traffic side to help reduce car to car collisions, which would tend to be more deadly.<\/li>\n<li>Many early American motorized vehicles actually placed the steering wheel on the right hand side of the car, even though America used the keep-right rule.\u00a0 This practiced finally was put to an end largely due to Henry Ford; he preferred the left side steering wheel.\u00a0 Ford cars thus adopt the left hand side steering wheel. \u00a0Due to their popularity, this effectively squashed the right hand steering wheel cars in America.<\/li>\n<li>According to research done in 1969 by J.J. Leeming, keep-left countries have a much lower collision rate than keep-right countries.\u00a0 It is thought the reason behind this is that most people\u2019s right eye is their dominant eye.\u00a0 Thus, the right eye in keep-left traffic is the one closest to oncoming traffic and so should reduce collisions.\u00a0\u00a0 Another theory as to why this might be is that most people are right handed, so when driving a manual transmission car in a keep-left country, most people\u2019s dominant hand is on the steering wheel; this could help in a person\u2019s ability to maneuver accurately.<\/li>\n<li>The people of Timor drive on the right in East Timor and the left in West Timor\u2026\u00a0 Ambidextrous drivers. \ud83d\ude42<\/li>\n<li>Most horse riders and cyclists will naturally mount the horse or bike from the left hand side.\u00a0 In the cyclist\u2019s case, this is why most bike chains and gears are on the right side of the bike so that the rider can walk along on the left side of the bike and not worry about getting pants or shoe laces caught in the gearing while walking beside the bike.<\/li>\n<\/ul>\n<span class=\"collapseomatic \" id=\"id69ef8d3d37b70\"  tabindex=\"0\" title=\"Expand for References:\"    >Expand for References:<\/span><div id=\"target-id69ef8d3d37b70\" class=\"collapseomatic_content \">\n<ul>\n<li>September 2009 Issue of Time Magazine<\/li>\n<li><a title=\"Why do the British Drive on the Left?\" href=\"http:\/\/www.straightdope.com\/columns\/read\/634\/why-do-the-british-drive-on-the-left\" target=\"_blank\">Why Do the British Drive on the Left<\/a><\/li>\n<li><a title=\"Why do American's Drive on the Right Hand Side of the Road?\" href=\"http:\/\/www.ehow.com\/about_5486536_do-drive-righthand-side-road.html\" target=\"_blank\">Why Do American\u2019s Drive on the Right Hand Side of the Road?<\/a><\/li>\n<li><a title=\"Right and Left Hand Traffic\" href=\"http:\/\/en.wikipedia.org\/wiki\/Right-_and_left-hand_traffic\" target=\"_blank\">Right and Left Hand Traffic<\/a><\/li>\n<\/ul>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p><a href='http:\/\/www.todayifoundout.com' title='Interesting Facts'>Today I found out<\/a> why some countries drive on the right and some countries drive on the left.
