| Location | Padang to Solok, West Sumatra |
| Length | ~15 km (9.3 miles) |
| Max Gradient | Up to 45% in specific sections |
| Hazard Level | High (Landslides & Sharp Hairpins) |
Why is Sitinjau Lauik so dangerous?
The road is world-renowned for its extreme hairpin bends and steep inclines. The most critical section features a turn so sharp and steep that large trucks and buses often lose traction or stall, requiring "spotters" and local assistance to navigate. The road surface is notoriously slippery, especially during the monsoon season when frequent rain and fog drastically reduce grip and visibility.
Technical Challenges and Infrastructure
- Extreme Gradients: Some sections of the climb reach a staggering 45% gradient, making it one of the steepest paved commercial routes in Southeast Asia.
- Heavy Logistics: Despite its dangerous geography, it remains a main artery for heavy cargo. The constant flow of overloaded trucks creates a high-risk environment.
- Landslide Risk: The geological setting makes the route highly susceptible to landslides. Recent events have caused significant traffic jams and fatalities, particularly at the "Panorama 1" area.
Future Improvements: The Sitinjau Lauik Flyover
Due to the high frequency of accidents, the Indonesian Ministry of Public Works has signed an agreement to construct the Sitinjau Lauik I Flyover. This infrastructure project aims to bypass the most dangerous curves with a viaduct, significantly improving safety and traffic flow for heavy vehicles.
Driving Advice
The route is crowded 24/7. If you plan to drive this road, avoid the rainy season if possible. Ensure your vehicle’s braking and cooling systems are in perfect condition. The descent requires expert use of engine braking to prevent terminal brake failure.
