Without a doubt, Mexico has an extensive network of highways connecting various points in the country. However, some of these roads are more dangerous than others due to their topography.
It should be noted that these roads are dangerous because they include steep slopes, sharp curves, very straight road surfaces, and abrupt changes in elevation. These conditions can make vehicle control difficult, increasing the risk of accidents.
These are the 7 most dangerous roads in Mexico, by topography:
- Matehuala-Monterrey

This road is unusual because it has a very long, “boring” straight road, which can cause you to be careless and cause an accident.
Due to its flatness, it encourages drivers to drive at high speeds, exceeding the established and recommended limits, making it one of the most dangerous.
Another factor that makes it dangerous is that lubricating oil can be found in some sections, which could cause slips and potentially lead to accidents.
- Mexico-Puebla, one of the most dangerous highways in Mexico

This highway is 103 kilometers long. It passes through the Río Frío area, so there is a high chance of the pavement freezing due to the weather.
If you head toward Mexico City, past Río Frío, you will see extremely dangerous and sharp curves.
- Cumbres de Maltrata

This is a highway that follows a steep mountain at the point where the states of Puebla and Veracruz meet. Due to the extremely dangerous curves and steep slopes, this road requires frequent use of the brakes.
For this reason, it is essential to stay focused, as any distraction could turn into an accident.
- Federal Highway 15D, from Guadalajara to Ciudad Juárez

This is undoubtedly one of the most dangerous highways due to the weather conditions it passes through, coupled with its heavy traffic, which considerably increases the risk of accidents.
- Federal Highway 190, from Puebla to Tehuacán

The constant sharp curves make this highway one of the most dangerous, given the difficulty in braking vehicles, which increases the risk of accidents.
Furthermore, the roads in several municipalities of the Red Triangle have become key points for robbers in recent years.
- Federal Highway Lázaro Cárdenas to Uruapan; one of the most dangerous in Mexico

This highway is considered one of the most dangerous not only for truckers but also for tourists, thanks to its several steep slopes. A high number of robberies have also been recorded between kilometers 145 and 155.
- Federal Highway 120, from Puebla to Cuernavaca

The highway is dangerous due to overconfident drivers, who collide with other slow-moving vehicles on the curves. Weather conditions such as rain and low temperatures also increase the risk.
So now you know, if you’re traveling on any of these highways, you should take certain precautions, such as:
Travel during the day, when visibility is better
Respect the speed limit for road conditions
Be careful on curves and reduce your speed before entering them
Do not drive while tired or distracted
It’s also important to be informed about weather conditions in the area
