Expressway collisions tend to be more serious than those on other types of roads because expressway are at higher speeds.
An expressway is a wide road that is specially designed so that a lot of traffic can move along it very quickly. It is usually divided, so that traffic travelling in one direction is separated from the traffic travelling in the opposite direction.
The present maximum speed limit for cars on expressways is 120 km/h, hence collisions are more serious.
