In September and October 1994, and January 1995, roadside surveys in conjunction with enforcement checkpoints were conducted in 15 North Carolina counties. These surveys sought: (1) to provide a population-based estimate of drinking-driving in the state and (2) to obtain baseline and follow-up data on drinking-driving in 4 areas targeted in a multifaceted intervention. Surveys conducted in conjunction with enforcement checkpoints differ from those not associated with enforcement actions in several ways. This paper focuses on these differences, emphasizing both the advantages and disadvantages of such cooperative ventures. Political, logistic, and research dimensions of the different procedures are discussed. It is concluded that, on balance, combining surveys with enforcement constitutes a viable alternative procedure for obtaining valid BAC (blood alcohol concentration) data from the driving public. (A)
