Evaluation of the Idaho (Bicycle) Stop Laws in the Pacific Northwest
The Oregon legislature recently passed a bill legalizing a type of Stop as Yield Law, similar to the “Idaho Stop”. The Oregon traffic law allows bicyclists to yield at stop signs and flashing red lights, as opposed to being required to make a complete stop. The law became effective on January 1, 2020. As a result, the Oregon Department of Transportation’s Transportation Safety Division would like to know the potential safety implications of the law. This project seeks: (1) to clarify the anticipated safety impact of the Stop as Yield (“Idaho Stop”) for all roadway users in Oregon (and its potential application in neighboring states such as Washington where such a law is being considered), and (2) to evaluate the historical impact this law has had in the state of Idaho since adoption in the early 1980s. This research will include both (1) an on-line expert survey sent to transportation agency staff in the region who have experience with the Idaho Stop and (2) Human-in-the-loop simulator studies using the bicycle and driving simulator at Oregon State University to collect data on likely cyclist and driver responses to varying conditions.
