People’s lack of safety awareness as they break traffic rules is a contributing factor.Think of an occasion where delivery men rush quickly at a crossing,even though the red light is on.In order to deliver the goods to the customers in time,they risk their lives on the hustle and bustle streets.Such misconducts not only pose threats to other commuters,but also bring tragedies to themselves,sometimes fatal.This is no exaggeration about this.Subject to data,there is higher casualty rate being reported for delivery men.
