45.1 | 1974/ 01 |
An Abstract of An Evaluation of Some Additional Factors Influencing the Effectiveness of Warning LettersTo determine the effectiveness of two types of warning letters and an informational pamphlet in reducing the subsequent collision and conviction records of pre-negligent drivers. An additional study objective was to determine the effectiveness of a fo llow-up reinforcement letter se nt to collision- and conviction-free drivers. These hypotheses were suggested by an earlier warning letter study (McBride & Peck, Report #30). This study was designed to attempt replication of the previous results. |
