As a general rule, how is the safety level of motorways and dual carriageways considered in comparison with conventional roads?

Question

DentroTest · Accepted Answer

Motorways and dual carriageways are high-capacity roads designed specifically to maximize traffic flow and safety. They are noticeably safer than conventional roads because of their structural characteristics: they have independent, physically separated roadways for each direction of travel (which practically eliminates head-on collisions), they have no crossings or intersections at the same level, and they have no direct access from adjoining properties. Although traffic travels faster on them, the fatal accident rate is considerably lower than on secondary or conventional roads.
