Examine Feasibility of Alcohol Interlocks for Motorcycles

The objective of this study is to determine the feasibility of the use of alcohol ignition interlocks for motorcycles. A study design will be developed to determine the feasibility of using alcohol ignition interlocks on motorcycles to reduce impaired motorcycle operation. Data on existing use of motorcycle interlocks for impaired drivers will be collected. States that use interlocks on motorcycles for impaired driving offenders will be identified, as well as why they are being used in the State, if the interlocks replaced other sanctions or are an additional sanction, and if they replaced sanctions what sanctions the interlocks may have replaced. Available data on motorcycle interlock use from the States (laws, frequency of use, how used, etc.) will be identified and documented. In addition, States using interlocks, as well as vendors and installation experts, will be contacted to gather data on any operational issues, such as weather exposure, vibrations, battery usage, dust, rolling restarts, etc., that may affect the practicality and functionality of using motorcycle interlocks, as compared to interlocks installed on automobiles. The data and data sources on interlock use and operational issues will be cataloged and summarized, and this information on the feasibility of motorcycle ignition interlocks will be analyzed. A final report will be submitted detailing the project’s objectives, methodology, results, and conclusions.
