[Successful prevention of tractor accidents in Sweden]

A decrease in the incidence of tractor roll-over fatalities, from 15/100,000 farm tractors for the period 1957(60 to 0.1/100,000 for the period 1986(90, was associated with a corresponding increase in the proportion of farm tractors equipped with roll-over protection structures (ROPS) from 6 to 93 per cent. Thus, the Swedish approach to the prevention of serious injuries due to tractor roll-over, entailing the compulsory equipment of new tractors with ROPS from July 1st 1959, may be said to have been successful. No other country seems to have introduced such effective safety regulations for the prevention of these injuries.
