Characteristics of threats on non-urban sections of national, provincial, district and communal roads of the swietokrzyskie province in Poland have been the subject of the work. The data source for the analyses covers the period of 1999-2004 and has been taken out from police road incident database files. There are differences in casualty structures depending on the category of a road. The lower the category of a road is the higher the global risk for most unprotected and most inexperienced road user is: the percentage of casualties among pedestrian children and young drivers increases as a rank of a road decreases. The proportion of casualties of one-track vehicle drivers is higher on roads of lower technical classes (district and communal) than on roads of higher classes (national and provincial). On the other hand, accident severity indexes (expressed in killed per total casualties) indicate more serious threats on roads that play more important role in a communication network system, such as national and provincial roads.
