"We hope to learn about things that bicyclists do which may help them avoid traffic accidents. There will be questions about .....
- your normal practices while bicycle riding
- traffic accidents or near accidents which you may have had while bicycling
- other factors (such as the amount of riding you do) which might affect your risk of having an accident."
Most of the survey questions seemed pretty reasonable. There were a couple about behavior at stop signs and stop lights; I added a note explaining that I reside in Idaho, where cyclists aren't required by law to stop at signs.
