Are we allowed to drive at less than 60 km per hour on a dual carriageway when there is heavy fog?
Highways and motorways
Explanation
Driving in **fog** is a situation that requires special precautions due to **reduced visibility** and the decreased grip of tires on the wet road. In these conditions, it is essential to **moderate speed** to ensure safety.
- Fog makes it difficult to see the road, signs, and other vehicles, increasing the risk of accidents. Therefore, it is important to **drive slowly** and maintain a **large safety distance** from other vehicles.
- Although on **motorways and highways** the minimum permitted speed is 60 km/h, there are exceptions that allow driving more slowly. One of these exceptions is when weather conditions, such as fog, make it dangerous to maintain the minimum speed.
- In foggy situations, it is crucial to **pay attention to signs** and avoid overtaking other vehicles unless necessary. Additionally, it is recommended to turn on **dipped headlights and fog lights** to improve visibility.
Therefore, on a highway with heavy fog, it is correct to drive at less than 60 km/h to **adapt to the environmental conditions** and ensure the safety of all road users.
