During a recent three-part series on BBC2, World's Most Dangerous Roads, six celebrities embarked on three terrifying car journeys, in Peru, Nepal and Alaska.
Here we highlight 15 of the world's most dangerous places to head out for a spin.
The North Yungas Road, Bolivia
Also known as El Camino de la Muerte or "Death Road", this 60km track was built by Paraguayan prisoners in the 1930s and takes fearless motorists from the Bolivian capital of La Paz to the town of Corioco. Traffic travels in both directions, but the road is rarely more than three metres wide and there are no guard rails. Heavy rain and fog often add to the danger, and one minor miscalculation can mean a fall of up to 600 metres. The road has claimed thousands of lives, and crosses mark many of the spots where vehicles have fallen. The high death toll and spectacular setting has also encouraged fearless cyclists to attempt the journey on two wheels. The road has been improved in recent years, and a new section now bypasses one of the most dangerous parts of the old route.
Skippers Road, New Zealand
Built in the late 19th century to give miners access to a gold-rich canyon, Skippers Road is now a popular day trip for thrill-seeking tourists from nearby Queenstown. Motorists must apply for a permit before attempting to tackle the road and many car insurance companies will not provide cover in the event of an accident. Make it down to the river safely, and you can sign up for a bungee jump or a white water rafting excursion.
Karakoram Highway, China & Pakistan
One of the world's highest paved roads, the Karakoram Highway runs from Abbottabad in Pakistan (renowned as the location of Osama Bin Laden's hideout) to the Chinese city of Kashgar. It passes through stunning scenery, making it popular with cyclists and bikers, but there are many dangers, including monsoon rains, landslides, heavy snow and altitude sickness.
Stelvio Pass, Italy
Although it's well paved, motorists negotiating the Stelvio Pass - which connects the Italian region of Lombardy with Austria - should expect a challenge. For those approaching from the north, there are an astonishing 48 hairpin turns to contend with, and glorious Alpine views to break your concentration. BBC's Top Gear voted it "the greatest driving road in the world".
Canning Stock Route, Australia
Perhaps the world's remotest road, the Canning Stock Route traverses 1,850km (1,150 miles) of empty desert and is a popular journey for adventurous petrolheads. You'll need up to three weeks, a four-wheel drive vehicle, space for food, water and spare parts, and at least a basic knowledge of how to fix a faulty car. Fuel drops will often need to be organised in advance, although petrol can be purchased at one or two Aboriginal communities along the way. There are also a number of wells en route.
Taroko Gorge, Taiwan
This narrow mountain road offers spectacular views for brave drivers. Heavy rain often results in landslides, and this region typically experiences three or four cyclones each year, with more than a metre of precipitation falling each time. Check the weather forecast.
Dalton Highway, Alaska
This isolated 414-mile highway was built as a supply road to support oil exploration in Alaska. There are just three towns on the way, with a total population of 60 people. Don't attempt the journey in your trusty Ford Mondeo. The giant trucks that ply the route kick up huge clouds of dust, reducing visibility to zero, and the road is littered with mammoth pot holes. There is also freezing Arctic weather to contend with.
This colossal road links Algiers in the north with Lagos in the south, passing through 4,500km (2,800 miles) of barren landscape and desert. Around 85 per cent is paved, but most of it is in poor condition, so you should familiarise yourself with changing a flat tyre before setting off. Fuel and water facilities are few and far between. You may have to endure temperatures of up to 50°C and sandstorms sometimes block the road.
Another road favoured by the gentlemen from Top Gear, Transfagarasan twists and turns for 90km (56 miles) around the tallest of Romania's Carpathian mountains and features dozens of hairpins, tunnels and sharp descents. It was built in the Seventies during the rule of communist dictator Nicolae Ceausescu. Six million kilos of dynamite were used during its construction and at least 40 soldiers were killed.
Sichuan-Tibet Highway, China
This 2,412km (1,498 miles) road links Chengdu and Lhasa and traverses more than a dozen mountains, guarenteeing countless hair-raising moments. The scenery is magnificent however, making it a popular journey for independent travellers.
A report in the New York Times last year likened this 40-mile road to Bolivia's El Camino de la Muerte. Vertical drops, sharp turns and kamikaze drivers mean the highway "claims so many lives so regularly that most people stopped counting long ago". Not to mention the fact that this is Taliban territory.
Things were little better before the road was built. In 1842, the journey was made on foot by British forces retreating from Kabul. Some 16,500 soldiers and their families were killed or captured on the way, with just one, William Brydon (and Harry Paget Flashman, according to George McDonald Fraser's novel), making it to Jalalabad alive.
One of a number of roads to have received the unenviable distinction of "Britain's most dangerous road", the A537 - or the Cat and Fiddle Road - runs between Buxton and Macclesfield. It's a windswept route, punctuated by sharp, blind bends, and the high number of accidents (there were 21 serious crashes in 2008) are largely blamed on motorcyclists. Among the country's other high-risk roads are the A5012 (Pikehall to Matlock), A621 (Baslow to Totley), A625 (Calver to Sheffield), A54 (Congleton to Buxton), A581 (Rufford to Chorley), A5004 (Whaley Bridge to Buxton), A675 (Blackburn to Preston), A61 (Barnsley to Wakefield) and the A285 (Chichester to Petworth).
