Why does the UK drive on the left? This was just one of the motoring mysteries our readers asked us about. Here are the answers.

Why does the UK drive on the left?

Gareth Edmunds, 59, from Bristol, said he was curious as their own families hosts English language students from all over the world.

“As I drive them around I hear them wince as they find an oncoming auto to our right and think we’re going to crash – it’s a question that always crops up, ” he said.

“My pet theory is that it’s something to do with times gone by when if you met a stranger on the road you’d pass on the left so your weapon limb was on their side.”

Mr Edmunds’ theory is one shared by Stephen Laing, curator of the British Motor Museum in Warwickshire. He said here today dated back to Roman hours.

“Most people are right handed, naturally mount a horse from the left and so need their right hand free for combat, ” he said.

“Roman armies marched on the left hand side of the carriageway and this is a convention that stayed.”

Motoring author Giles Chapman said Britain’s Highway Act of 1835 enshrined driving on the left in law for this country and its colonies.

“The rule was exported, for example, to Japan, where British technologists schemed its railways to drive on the left, leading to a similar proclamation for road vehicles.”

Why do some other countries drive on the right?

Richard Mace, 63, who lives near Chatham in the south-east of England, said he had always been curious as to why they drive on the right in the US.

“The reason I have been given goes back to when wagons were depicted by oxen, ” he said. He could be on the right track.

In the late 1700 s wagons pulled by ponies arranged in pairs became increasingly popular, Fraser McAlpine wrote for BBC America .

The driver sat on the back of the rear left-hand horse, to whip the others right handed.

The best style for one wagon to pass another without banging wheels was the right hand side of the road, according to McAlpine.

What would it cost to convert the UK to drive on the right?

The government examined such a plan in 1969, two years after Sweden switched to driving on the right.

Its report rejected the idea on grounds of safety and costs.

In 1969, the financial burden of making the switching was calculated by the government to be PS264m.

That equates to about PS4bn in today’s money. But given the huge advances in infrastructure since 1969 this would now be an extremely conservative estimate.

Stephen Laing, curator at the British Motor Museum, said he could not watch Britain swapping sides.

“I think we are kind of set in our routes, ” he said. “The infrastructure is built around driving on the left hand side. I can’t really be understood that changing in the future.”

The Department for Transport said: “We do not have a policy on this because it’s not something we are interested in at this time.”
