Why do the English drive on the left side of the road?

There is a logic that has evolved since olden days about keeping to the left on the road. In olden days people wanted to protect themselves using their sword while they were passing each other on the road. To accomplish this they had to be in the best possible position to use their sword in order to protect themselves. Since most people were right handed, they felt it convenient to keep to the left and use the sword in their right hand. History states that keeping to the left came into force as early as 1300 AD, when Pope Benefice told all his pilgrims to keep to the left. Archaeologists found in 1998 that a track leading to a roman quarry near Swindon, England, had grooves on the road that were deeper on the left side. These suggest that Romans drove on the left, since carts would leave the quarry heavily loaded and enter them empty, which explains the reason why the grooves on the left were deeper than the ones on the right.

Northcote Parkinson believed that in olden days, travellers on horseback rode on left side of the road. Since most people were right handed, the horsemen would hold the reins with their left hand and keep their right hand free to either offer in friendship to passing riders or to defend themselves with a sword from enemies if necessary. However in 1756, with regards to LondonBridge, the first legal reference was made to order the traffic to remain on the left. With passing days, as the horse traffic increased, the general Highways act of 1773 was passed which recommended that horse traffic should remain on the left. Later in 1835 this became a law as part of the Highways Bill. The keep left rule also spread far across India, Australasia and much of Africa due to the Britain’s imperial expansion, while many African countries changed to right after they became independent.

Why the British Drive on the Left?

Left hand driving for vehicles comes from old times, even before there were any cars. People preferred to be on the left hand side while driving, so that they had their right hand free to defend themselves against robbers either using a sword or gun. A common question that arises is why people drive on the right in other parts of Europe. It is believed that the reason behind this is Napoleon, who after conquering Europe, fixed the major roads and established traffic on the right side. Some believe that he did so to go against the way British travelled, while others believe that it was easier for him to control the horse with his right hand, and hence he made everybody else travel on the same side as he travelled.

Fascinating! I imagine it will always be that way. I know I would hesitate to drive in a country with left hand driving. It seems so unnatural to me, but I'm sure right hand driving seems just as unnatural to left hand driving, too.

Interesting Hub. I wonder if we will continue to drive on the left or the government will change it. Having said that, maybe we should just stick to it, as their will be too much upheaval. Lol. Nice one. :)
