Dagen H (H day), today usually called “Högertrafikomläggningen” (“The right-hand traffic diversion”), was the day on 3 September 1967, in which the traffic in Sweden switched from driving on the left-hand side of the road to the right. The “H” stands for “Högertrafik”, the Swedish word for “right traffic”. It was by far the largest logistical event in Sweden’s history.
There were various major arguments for the change:
- All of Sweden’s neighbours (including Norway and Finland, with which Sweden has land borders) drove on the right, with 5 million vehicles crossing those borders annually.
- Approximately 90 percent of Swedes drove left-hand drive (LHD) vehicles. This led to many head-on collisions when passing on narrow two-lane highways, which were common in Sweden due to the fact that the country’s low population density and traffic levels made road-building expensive in per capita terms. City buses were among the very few vehicles that conformed to the normal opposite-steering wheel rule, being left-hand drive.
However, the change was widely unpopular; in a 1955 referendum, 83 percent voted to keep driving on the left. Nevertheless, on May 10, 1963, the Swedish Parliament (Riksdagen) approved the Prime Minister Tage Erlander‘s government proposal of an introduction of right hand traffic in 1967, as the number of cars on the road tripled from 500,000 to 1.5 million, and was expected to reach 2.8 million by 1975. A body known as Statens Högertrafikkommission (HTK) (“the state right-hand traffic commission”) was established to oversee the changeover. It also began implementing a four-year education programme, with the advice of psychologists.
The campaign included displaying the Dagen H logo on various commemorative items, including milk cartons and underwear. Swedish television held a contest for songs about the change; the winning entry was “Håll dig till höger, Svensson” (‘Keep to the right, Svensson‘) written by Expressen journalist by Peter Himmelstrand and performed by The Telstars.
As Dagen H neared, every intersection was equipped with an extra set of poles and traffic signals wrapped in black plastic. Workers roamed the streets early in the morning on Dagen H to remove the plastic. Similarly, a parallel set of lines were painted on the roads with white paint, then covered with black tape. Before Dagen H, Swedish roads had used yellow lines.
On Dagen H, Sunday, 3 September, all non-essential traffic was banned from the roads from 01:00 to 06:00. Any vehicles on the roads during that time had to follow special rules. All vehicles had to come to a complete stop at 04:50, then carefully change to the right-hand side of the road and stop again (to give others time to switch sides of the road and avoid a head on collision) before being allowed to proceed at 05:00. In Stockholm and Malmö, however, the ban was longer — from 10:00 on Saturday until 15:00 on Sunday — to allow work crews to reconfigure intersections. Certain other towns also saw an extended ban, from 15:00 on Saturday until 15:00 on Sunday.
The relatively smooth changeover saw a reduction in the number of accidents. On the day of the change, only 157 minor accidents were reported, of which only 32 involved personal injuries, with only a handful serious. On the Monday following Dagen H, there were 125 reported traffic accidents, compared to a range of 130 to 198 for previous Mondays, none of them fatal. Experts suggested that changing to driving on the right reduced accidents while overtaking, as people already drove left-hand drive vehicles, thereby having a better view of the road ahead; additionally, the change made a marked surge in perceived risk that exceeded the target level and thus was followed by very cautious behaviour that caused a major decrease in road fatalities. Indeed, fatal car-to-car and car-to-pedestrian accidents dropped sharply as a result, and the number of motor insurance claims went down by 40%.
These initial improvements did not last, however. The number of motor insurance claims returned to ‘normal’ over the next six weeks and, by 1969, the accident rates were back to the levels seen before the change.

The wreck of the 1908 Wright Flyer that seriously injured Orville Wright and killed Lt. Thomas E. Selfridge, the first person to die as the result of an airplane accident; September 17th, 1908
During flight trials to win a contract from the U.S. Army Signal Corps, pilot Orville Wright and passenger Lt. Thomas Selfridge crash in a Wright Flyer at Fort Myer, Virginia. Wright is injured, and Selfridge becomes the first passenger to die in an airplane accident.
After Wilbur and Orville Wright made their historic first-ever airplane flight Dec. 17, 1903, they spent the next few years largely in seclusion developing their new invention. By the end of 1905 their interest in aviation had changed from curiosity and the challenge of flying, to the business of how to turn aviation into an industry: They were looking for a business model.
Unfortunately their first attempts to attract the United States government to the idea of using airplanes were turned down. The military just didn’t see how the airplane could be used in any practical way.
For two-and-a-half years the Wright brothers did not fly. They continued to work on their airplane, but put more and more time into building the business. Eventually they were able to attract interest from both the French and British governments, but by 1907 they still did not have any firm contracts.
But the Wright brothers were awarded two contracts in 1908: one from the U.S. Army and the other from a French business. The Army contract was for a bid to fly a two-man “heavier-than-air” flying machine that would have to complete a series of trials over a measured course. In addition to the $25,000 (about $600,000 in today’s buying power) bid, the brothers would receive a $2,500 bonus for every mile per hour of speed faster than 40 mph. No supersonic stealth fighters just yet.
Because they had not flown since October 1905, the brothers returned to Kitty Hawk to test their new controls to be used on the Wright Flyer in the Army flight trials. Despite some difficulty getting used to the new controls, both brothers managed to get some practice flying in during the stay in North Carolina.
Wilbur was in France during the summer of 1908 demonstrating the new Wright Flyer to Europeans (video). Orville remained in the United States and on Sept. 3 made his first flight at Fort Myer, where the Army trials were set to begin.
The flight tests set out by the Army required the airplane to carry two people for a set duration, distance and speed. There was a committee of five officers to evaluate the Wright Flyer’s performance, including the 26-year-old Selfridge.
Selfridge was a member of the Aerial Experiment Association and had designed the group’s first powered airplane. The Red Wing first flew on March 12, 1908, but crashed and was destroyed on its second flight a few days later.
During the first two weeks of September Orville made 15 flights at Fort Myer. He set three world records Sept. 9, including a 62-minute flight and the first public passenger flight. By Sept. 12 Orville had flown more than 74 minutes in a single flight and carried Maj. George Squier for more than 9 minutes in one flight.
On Sept. 17 Orville was flying Selfridge on another of the test flights. Three or four minutes into the flight, a blade on one of the two wooden propellers split and caused the engine to shake violently. Orville shut down the engine but was unable to control the airplane.
The propeller had hit a bracing wire and pulled a rear rudder from the vertical position to a horizontal position. This caused the airplane to pitch nose-down, and it could not be countered by the pilot.
The Wright Flyer hit the ground hard, and both men were injured. Orville suffered a fractured leg and several broken ribs. Selfridge suffered a fractured skull and died in the hospital a few hours later.
Despite the crash, and the first passenger death in an airplane, the Army was significantly impressed with the Wright Flyer and allowed the brothers to complete the trials the following year. They were awarded the contract. Along with success in France, the Wright brothers were well on their way to establishing what would become one of the most successful aviation companies during the early days of flying.
Because of the crash, the first Army pilots were required to wear helmets similar to early football helmets in order to minimize the chance of a head injury like the one that killed Selfridge.
Though the early days of aviation continued to be full of danger, airplane travel today is statistically one of the safest modes of transportation based on passenger miles traveled. Between 1995 and 2000 there were about 3 deaths per 10 billion passenger miles flown.
Francis Rawdon Moira Crozier was born in 1796 into a wealthy family in the Irish linen town of Banbridge, County Down. His father, George Crozier, was a prominent solicitor who acted for Ireland’s most powerful land-owning families, and he was named after Francis Rawdon, the Earl of Moira.
In 1810, three months before his 14th birthday, Crozier enlisted in the Royal Navy and was immediately thrown into the Napoleonic wars. On one of his earliest voyages, his ship became lost in the Pacific Ocean and unexpectedly arrived at tiny Pitcairn Island, where the crew met the sole surviving mutineer from the Bounty.
After the end of the Napoleonic wars in 1815, the Admiralty turned to exploration in an attempt to find work for its ranks of idle officers and to expand the British Empire. Arctic discovery was a key ambition during this energetic burst of exploration, which produced men such as Franklin, Parry, the Rosses and Crozier.
Crozier’s first polar expedition came in 1821, when he volunteered to join Parry’s attempt to navigate the Northwest Passage, a feat that had eluded sailors for centuries. They returned after two years without success, but Crozier went north again a year later when Parry took the vessels Fury and Hecla on another vain bid to locate the passage. Disaster was only narrowly averted when Fury was wrecked in Prince Regent Inlet, and the entire party limped home on board Hecla.
In 1827, Crozier joined Parry and James Clark Ross in an arduous slog to reach the North Pole. The party, dragging heavily laden boats, trekked for more than 1,000 kilometres, but advanced only 275 kilometres north because the remorseless drift of the pack ice carried them steadily south. It was akin to walking the wrong way up a fast-moving escalator, and the men survived thanks largely to the depots earlier laid down by the diligent Crozier. But the ‘furthest north’ record of 82° 45’ stood for almost half a century.
On successive journeys, Crozier demonstrated his reliability and an aptitude for the painstaking business of magnetic and astronomic readings. In 1827, he was made a Fellow of the Royal Astronomical Society and was elected a Fellow of the prestigious Royal Society in 1843. His prominent sponsors included the astronomer Sir John Herschel and Sir Francis Beaufort, creator of the Beaufort scale and one of the co-founders of the Royal Geographical Society.
Crozier’s most accomplished feat was the mammoth four-year journey to Antarctica in Erebus and Terror with James Clark Ross, which arguably ranks as the 19th century’s most outstanding voyage of maritime discovery. He captained Terror and never lost a man – a rare achievement at the time.
Setting out in 1839, the Erebus and Terror expedition was the last great journey made under sail, penetrating the pack ice of the Southern Ocean and discovering vast tracts of the Antarctic continent. It also bequeathed many of the now familiar geographical names to the Heroic Age of Exploration, including Mount Erebus, Ross Island and McMurdo Sound. The Great Ice Barrier, where Scott’s party perished in 1912, was so named because it presented a barrier to Erebus and Terror (it was re-named the Ross Ice Shelf in the 1950s). And Cape Crozier, the windswept headland on Ross Island that was later immortalised by Apsley Cherry-Garrard’s book on Scott’s expedition, The Worst Journey in the World, is now renowned for its emperor penguin colony.
However, the Antarctic journey took a heavy toll on both Crozier and Ross. On their return, witnesses were shocked at the way their hands trembled – the tremors so pronounced that they could hardly hold a glass.
Sadly, Crozier was also suffering from a broken heart. On the voyage south, the ships had stopped at the penal colony of Van Diemen’s Land (now Tasmania), where Crozier fell deeply in love with Sophy Cracroft, the flirty niece of the old explorer Sir John Franklin, who had been appointed the island’s governor. His repeated proposals of marriage were rejected because Cracroft refused to become a captain’s wife. ‘She liked the man, but not the sailor,’ her aunt once confided.
Heartbroken and depressed, Crozier elected to head north again in 1845 when the Admiralty launched a fresh attempt to navigate the Northwest Passage in Erebus and Terror. Although Crozier was the most experienced polar captain still serving, the Admiralty gave command of the expedition to Franklin, an overweight 59-year-old who hadn’t taken a ship into the ice for 27 years. It was a snub that hurt Crozier, and he probably should have chosen that moment to retire from exploration. But in a vain attempt to appeal to Cracroft, Crozier volunteered to travel as Franklin’s deputy and assume command of Terror.
In his last letter home, a melancholic Crozier wrote: ‘In truth I am sadly lonely.’ More pertinently, he was worried that the expedition had sailed too late in the season and also questioned Franklin’s leadership, writing that ‘[Franklin] is very decided in his own views but has not good judgement’.
Erebus and Terror crossed Baffin Bay during the summer of 1845 and entered the treacherous Arctic waterways of Lancaster Sound with 129 officers and men aboard. They were never to return.
Disaster struck in 1847, when the ships became trapped in the ice in Victoria Strait. Shortly after, Franklin died and command of the expedition passed to Crozier. The ships were abandoned in 1848, and it was Crozier who inherited the hopeless task of leading about 100 starving survivors in a forlorn retreat across the ice. Men fell dead in their tracks; years later, examination of their bones revealed that some had resorted to cannibalism in the struggle to survive.
Crozier’s death march ripples with historical significance. At one point, the survivors reached the narrow Simpson Strait that runs between King William Island and mainland Canada. Unknown to Crozier, the strait was the last piece of the jigsaw that – at that point – made up the Northwest Passage. A little over 50 years later, the Norwegian Amundsen navigated the strait during the first navigation of the passage and graciously flew his ship’s colours in salute.
According to native accounts, a few desperate souls from the Franklin expedition clung to life for several years after the ships were abandoned, but none managed to find a route to safety. Crozier, the imperturbable and experienced commander, is thought to have been among the last to succumb.
Teddy Roosevelt on an expedition in Brazil – exploring the newly discovered River of Doubt; ca. 1914
Teddy and his son Kermit took the dangerous expedition together after his presidency. During the trip, a man was murdered, his escaped murderer was deliberately left in the jungle to die, and a third man drowned in the river rapids. Roosevelt himself nearly died of an infected wound and almost every person on the expedition was sick. There were not enough supplies and the boats were not adequate for the type of water they were traveling.
