Effect of Daylight Saving Time on the Number of Motor Vehicle, The Fatalities

A study of the effect of daylight saving time on motor vehicle fatalities indicates that a considerable number of injuries and deaths might be avoided annually if clocks were advanced one hour throughout the nation from the first Sunday in April to the last Sunday in September. This result is suggested by a study of the 1938 and 1939 motor vehicle accident record of sixteen large cities, each with a population in excess of 250,000. Fatal motor vehicle accidents numbered 5,731 in these cities during the two years embraced in the study.
