Program Description: Do SFSTs work for drugs? Yes, says one Michigan Study.
The Standardized Field Sobriety Test battery was developed to enable the administering officer to identify the presence of alcohol at intoxicating levels. They were validated initially for a .10% BAC, and were later validated for a .08% BAC, and arguably for a .05% level. But do they work for non-alcohol drugs? Or should revised SFSTs be developed for specific drugs as some have suggested? The issues of SFSTs for drugs, and related concerns such as meaningful blood levels, are frequent topics in court proceedings, particularly when drug-impairment is at issue. This presentation will provide an overview – and commentary on the above issues – of an officer-initiated and funded study on the usefulness and accuracy of SFSTs for non-alcohol drugs.

Program Description: Lowering the BAC limit: Lessons learned from research and practice in Canada
Impaired driving remains a leading contributing factor in road crashes in many jurisdictions and some US jurisdictions are exploring reducing their illegal BAC limit to .05, as was adopted by Utah.

This presentation will summarize Canada’s experiences and lessons learned with implementing a lower limit, and findings from research evaluating this approach. Important caveats and considerations to guide an implementation strategy will also be shared.
