What should be done if a vehicle is disabled and cannot be moved on the Autostrada?

When a vehicle becomes disabled on the Autostrada, it is crucial to prioritize safety and communicate the situation to other drivers. Setting up a warning triangle is essential because it alerts approaching vehicles of the hazard, reducing the risk of collisions. The triangle should be placed at a safe distance behind the vehicle, allowing sufficient time for other drivers to see and react appropriately.

Waiting for help in a safe location inside the vehicle is advisable, as it keeps the occupants protected from traffic. This strategy also ensures that help is more likely to arrive without additional incidents occurring due to an unmarked disabled vehicle on the side of the road.

The other options do not adequately ensure safety or visibility. For instance, driving away from the vehicle might lead to confusion and danger in that area. Leaving a note does not inform other drivers of the hazard immediately and does not provide any visual warning. Contacting roadside assistance is certainly important, but without a warning triangle, the vehicle remains a potential hazard on the busy highway, putting everyone at risk.
