Thank you for participating in "Scientific Evidence in DUI Cases." The survey should take between 10 and 20 minutes. You do not need to take the survey in one sitting. If you need to take a break and come back to it you may do so at any point once you have finished the background and subject matter questions. To take a break select the "I need to take a break and finish later" option and submitting your answeres to that point.
Please note that the survey is easier to take from a computer than a cell phone or similar touch screen devices
Should you need a calculator to answer any of the questions presented in the survey, the web calculator below has all the functionality that you will need.
