Saudi Highway 10 holds the record for the world's longest straight road

Saudi Highway 10 is recognized by the Guinness World Records as the longest straight road on the planet. The total length of the highway is approximately 1,480 kilometers, but it features a specific 240-kilometer segment between Haradh and Al Batha that runs in a perfectly straight line without any curves. While technically simple to navigate due to the lack of intersections or obstacles, the road presents unique challenges for drivers. The absence of landscape changes and reference points creates intense monotony, which can lead to driver fatigue and loss of concentration. Additionally, the unchanging horizon can distort the perception of speed, increasing the risk of human error. Despite its isolated desert environment, the road remains a vital transport artery. It serves as a major route for heavy goods vehicles connecting Saudi Arabia with neighboring Gulf states.
