In the present work, a 10-year database of rainfall-triggered landslides occurred in Calabria region (southern Italy) is used to underline the circumstances leading to damage to people caused by landslides along the road network of the analyzed region. The analysis is based on the fact that, where engineering methods are not cost-effective in reducing the danger related to rainfall-triggered landslides on an entire road network, it is crucial that vulnerable communities are aware of the hazards they face and know how to respond in an emergency. Such awareness must be founded on actual situations in which people can really be involved in, and which can change region by region or place by place. Knowledge of the leading causes of fatalities should inform public awareness programs and public safety police enforcement activities. In this work, the general regional framework obtained from the 10-year database analysis is compared to a local and more detailed analysis carried out on a state road track characterized by a long series of landslides activations since last century. According to the morphology of the area in which the road passes through, it is very difficult to find alternative and safer, road paths. Moreover, the importance of this road depends on the fact that it is often used as alternative path when the regional adjacent highway has to be close because it is affected by landslides or floods triggered by rainfall. Finally, the general regional sketch of damaging circumstances for drivers is compared to the local one obtained for the case study, in order to underline the methodological differences and the types of data necessary to extend the approach to the entire regional road network
