Highway 1, stretches 1,063 miles (1,711 km), along the Baja California Peninsula, from Cabo San Lucas in the south to Tijuana in the north. While some parts of the road are paved with asphalt, most of its barriers offer little more than token protection, as a result, large stretches should be taken at a snail’s pace. As there are many blind corners and drivers should always be alert for vehicles coming from the opposite direction.
Because of the lack of shoulders, road signs, and the fact that there are so many blind corners, accidents are common and, in many areas, you can see guardrails that are split open where previous drivers have missed their turns and met their doom.
Cetinje - Kotor road, Montenegro
Located on the coast of Montenegro, Cetinje is an historic road connecting the old city, Kotor, with the small city Cetinje, from which you can enjoy the spectacular view of Kotor bay along the way. As beautiful as it sounds, this road is famous for being one of the most hairpinned roads in the world. This curvy and mountainous road rarely permits you to go over 18 mph (30km/h). The most infamous part of the road is the Kotor Serpentine, a short 5 mile (8.3km) stretch with 16 hairpin turns. Usually when travelers remark about the danger of the roads in Montenegro, they're often referring to Cetinje.

Some days there are lanes for passing, but then other days, rock falls and get in the way, but at least there's the gorgeous coastal view, just don;t get too distracted, as often impatient local drivers make hunk at you to hurry it up. Enjoy, but be cautious.
Killar to Pangi Road (via Kishtwar), India
This hair-raising road should only be taken by experienced drivers who have nerves of steel. This rocky, road is about 100 miles long, with a 6-mile stretch that's particularly hazardous; as it looks as if you could fall off the roadway at any moment. You must be very patient as well if you choose this route, it's only wide enough for one jeep at a time to pass, and with no guardrails in sight, this dirt and gravel road is unstable in many parts.
The Highway road was built hundreds of years ago by locals and has not been maintained over the decades. One wrong move by a driver could send a vehicle down a vertical fall of 2,000 feet. This road is so frightening, that it’s even nerve wrecking to watch videos of people driving over it.
Nairobi-Nakuru Highway, Kenya
The Nairobi-Nakuru highway's 99 mile (159 km) stretch is notorious for being the most dangerous road in the country. The got it's infamous reputation mainly because its local driver's. Speeding, poor overtaking skills, and drunk driving (which is pretty common to see), are common, and if that wasn't bad enough, there hardly any traffic law enforcement in sight. Those factors, along with pedestrians and animals wandering into the road makes this highway one dangerous place to be, in fact, in one year alone, 320 people were killed on it.
While defensive driving lessons could make this road a bit safer, it's still quite risky. It was recently repaved in effort to lessen road traffic accidents, but sadly this still hasn't helped much. At least the Kenyan Government has recently begun to crack down on drunk drivers which is a major part of the problems s well.
Transfagarasan Road, Romania
In the Carpathian Mountains of Romania, and at an altitude of up to 6,000 feet, this highway is a shortcut between Transylvania and Walachia, and as is known to be one of the most difficult and dangerous in the world. This iconic highway has even been referenced in the television show Top Gear.
Drivers should be extremely cautious because not only is the oxygen much more rare on such a high altitude, but the road also drops so suddenly from the hill, you may feel as though you’re on a rollercoaster ride. Driving can very tricky since you can’t hit your breaks too suddenly since you never know if someone is coming up right behind you.
