What is the speed limit for sedans on the autostrada unless otherwise posted?

On the autostrada in Italy, the speed limit for sedans, unless otherwise posted, is indeed 130 km/h, which is approximately 81 mph. This speed limit is in place to ensure the safety of all road users and is part of Italy's comprehensive traffic regulations.

When driving on the autostrada, it is important to adhere to this limit because higher speeds can increase the risk of accidents. In addition, drivers should also be aware of changing speed limits in specific areas, particularly in construction zones or areas with lower visibility, where different speed limits may be enforced. Understanding and following these regulations is crucial for safe and responsible driving.
