In order to obtain information on the attitudes of drivers of heavy duty tractor-trailer configurations toward ride quality and safety and to assess the interrelationships among driver biographical, health status, and truck profiles as they affect comfort, safety, and causes of ride problems, a questionnaire was distributed to members of the International Brotherhood of Teamsters (IBT) and the Professional Drivers Council (PROD); three thousand six hundred eight teamsters and 299 PROD members returned completed questionnaires. Over 36 percent of the IBT drivers and 52 percent of the PROD drivers stated that they experienced 'problems which cause one major discomfort during normal operations or problems which make it almost impossible to drive the truck.' Several truck and biographical variables were found to be problems with respect to comfort and safety.
