The research is intended to measure the effectiveness of the interlock system in increasing safety belt usage. Three separate studies were conducted: (a) Among rental car customers at U.S. airports (to obtain a large body of data early in the 1974 model year); (b) among rental car customers at Toronto International Airport, where different types of use-inducing systems could be studied; and (c) among owners of private cars in the general population of vehicles. Study (a) was conducted at Miami, Chicago, and Los Angeles. Customers returning 1974 model rental cars at these airports were observed for their safety belt usage, and a subsample of nonusers immediately interviewed to determine the circumstances and attitudes surrounding their nonusage. Similar methods of observing and interviewing were followed at Toronto.
