An Assessment of Traffic Safety Culture Related to Driving After Cannabis Use

Started: June, 2015 End Date: November, 2016 Project ID #4W5483 Status: Ongoing

Objective

The objective of this project is to explore specific aspects of traffic safety culture that relate to the decision to drive after consuming cannabis.

Abstract

An important risk factor in traffic safety is use of drugs that impair driver perception, decision-making and skill. Cannabis has been shown to impair driver ability, and its use is on the increase. Several states have legalized recreational cannabis use, and more are considering legalization. Increased use of cannabis among drivers may pose a barrier to achieving a zero deaths strategy. Therefore, understanding the cultural factors that influence driving under the influence of cannabis is critical to address this problem. This research focuses on specific aspects of traffic safety culture that relate to the decision to drive after consuming cannabis. The project will seek to answer three critical questions: 1) How does culture compare between users and non-users of cannabis? 2) How does culture affect the decision to drive under the influence of cannabis? and 3) How does culture compare between states with and without legalized recreational use laws? By understanding the cultural factors that predict driving under the influence of cannabis (including the impact of legalization), transportation and public health agencies will be better able to bolster existing protective factors and develop interventions to address risk factors.
