The law isn't everything: The impact of legal and non-legal sanctions on motorists' drink driving behaviors

摘要

udud - The effectiveness of drink driving countermeasures (such as sanctions) to deter motorists from driving over the legal limit is extremely important when considering the impact the offending behaviour has on the community. However, questions remain regarding the extent that both legal and non-legal factors influence drink driving behaviours. This is of particular concern given that both factors are widely used as either sanctioning outcomes or in media campaigns designed to deter drivers e.g., highlighting the physical risk of crashing. udududud - This paper reports on an examination of 1253 Queensland motorists’ perceptions of legal and non-legal drink driving sanctions and the corresponding deterrent impact of such perceptions on self-reported offending behaviour. Participants volunteered to complete either an online or paper version of the questionnaire. udududud - Encouragingly, quantitative analysis of the data revealed that participants’ perceptions of both legal sanctions (e.g., certainty, severity and swiftness) as well as non-legal sanctions (e.g., fear of social, internal or physical harm) were relatively high, with perceptual certainty being the highest. Despite this, a key theme to emerge from the study was that approximately 25% of the sample admitted to drink driving at some point in time. Multivariate analyses revealed six significant predictors of drink driving, being: males, younger drivers, lower perceptions of the severity of sanctions and less concern about the social, internal and physical harms associated with the offence. However, a closer examination of the data revealed that the combined deterrence model was not very accurate at predicting drink driving behaviours e.g., 21% of variance. udududud - A range of non-legal deterrent factors have the potential to reduce the prevalence of drink driving although further research is required to determine how much exposure is required to produce a strong effect.
