Way to Drive is a smart phone-based driving telematics application. Research participants are invited to download the app, which uses phone sensors to track driving behaviors including mileage, hard breaking events, and handheld phone use while driving, measured as the phone screen being unlocked while the phone is in the hand and the vehicle is in motion. Before the study team launches a clinical trial using the app, the researchers will test its capabilities and reliability.

Inclusion Criteria:

• 18 or older (only adult drivers will be invited)
• Willing to download Way to Drive and allow it to track the user's location while the user is in motion (i.e. over 5mph)
• Will make at least 4 driving trips per week for the duration of the study.
• Able to provide informed consent

Exclusion Criteria:

• Under 18 Cannot complete online surveys
• Does not have smart phone
• Not willing to download Way to Drive app and allow location tracking while in motion
• Will not be driving at least 4 times per week during the study.

Adults who completed in the study team's recent clinical trial with User Based Insurance customers and stated interest in being contacted about further research opportunities. The adults participated in a driving monitoring study (May 2021) and met the eligibility criteria, including 4 trips per week.

Deidentified participant data will be made available to other researchers upon request.

Data will be made 5 weeks after request and indefinitely thereafter.
