On the SS3bis Bis Tiberina (E45), conditions of intense fog are reported, which could compromise visibility. The phenomenon occurs between 1.18 km after the Ponte Rio di Todi intersection and 467 meters before the Bettolle-Perugia intersection.

To ensure safety on the road, it is recommended to:

• Reduce speed: maintain a speed appropriate to the visibility conditions.
• Increase safety distance: maintain a greater distance between vehicles.
• Use dipped headlights: avoid full beam headlights that can reflect fog, increasing the risk of dazzling.
• Pay attention: remain focused and ready to stop in the event of obstacles on the roadway.

It is recommended that all motorists remain alert and travel with caution in these conditions.
