Drivers' Awareness of and Response to Significant Weather Events
and the Correlation of Weather to Road Impacts
I’m calling on behalf of the National Oceanic and Atmospheric Administration’s National
Weather Service, the University of Utah, and the Utah Department of Transportation. I’d like to
ask you a few questions about your driving, but first I need to make sure you are somewhere
safe to talk on the telephone. Are you driving right now?
If “No,” continue below (A).
If “Yes”: Sorry, I cannot interview you while you are driving. We’ll call you at another time.
Thank you. Good Bye.
A. The purpose of this interview is to learn how people respond to weather reports about driving
conditions. We are doing this study to improve how weather reports are given to the public.
Before we begin, I need to make sure you are eligible to participate.
Are you 18 or over ? No Yes
Do you have a driver’s license for driving in Utah? No Yes
Do you live in one of these areas: South Davis, Salt Lake or Summit County? No Yes
Do you travel regularly in the Salt Lake Valley? No Yes
If “No” to any of these, end the interview “I’m sorry, you are not eligible, thank you for your time”.
If yes to all four: “You are eligible to participate. Let me briefly explain our survey.”
I would like to ask you 10 to 15 questions which will take less than 10 minutes. Your
participation is voluntary, and you are free to skip any questions you choose not to answer.
There are no immediate benefits to you for participating, but your answers will help us improve
weather reporting in the state.
Personal information will not be saved or shared. We are not recording your name or telephone
number; we use only code numbers in our data file. This interview might be audio-recorded for
quality control and to check your answers to open-ended questions. The tapes will be destroyed
once we are certain we have accurately typed up your responses.
You can call the researcher, Carol Werner at 801 581 8938 or you can contact the Institutional
Review Board if you have questions regarding your rights as a research participant. Also,
contact the Review Board if you have questions, complaints or concerns which you do not feel
you can discuss with the interviewer. The University of Utah’s Institutional Review Board may be
reached by phone at (801) 581-3655 or by e-mail at irb@hsc.utah.edu.
