"Buckling Up" is a factsheet devoted to showing us the effectiveness of seatbelts: lap-to-shoulder seatbelts reduced the fatal injury risk in passenger car accidents by 45 percent, and in light truck accidents by 60 percent. In 2008, it is estimated that seatbelts saved the lives of 13,250 people older than four, and if everyone involved in a fatal crash had been wearing a seatbelt, a further 4,152 lives could have been saved.
