Traffic Safety Culture and Impaired Driving

Started: April, 2019 End Date: April, 2021 Project ID #4W7717 Status: Ongoing

Objective

The objective of this project is to develop a better understanding of belief systems that predict intention to drive after using cannabis.

Abstract

Cannabis use by U.S. adults has increased by 50% over the last decade, and over the same period, cannabis use by drivers has increased by an estimated 8 -12%.  Cannabis impairs psychomotor functions that can impair driving ability, which in turn may increase crash risk.  As a result, drug-impaired driving is a growing traffic concern.  While traditional approaches have focused on enforcement and education, another approach is to build a positive traffic safety culture, which can be described as shared values and beliefs that influence safe driving decisions.   Through this project, the Center for Health and Safety Culture will conduct research to develop a better understanding of belief systems that predict intention to drive after using cannabis. The research will include surveys of cannabis users and non-cannabis users in the state of Washington.  The findings will guide the development of culture-based interventions and strategies to sustainably reduce impaired driving.
