Without knowing the details of the proposal, this may be a bit hard to answer.
It would seem that expected findings would include information on the number of DWI and DUI arrests, as well as the number of crashes (fatal and non-fatal) that were related to DWI and DUI activity. Those would be important things to discover.
Then you could discuss the value of remaining sober behind the wheel based on the statistics and information provided in the findings.
