Abstract
In collaboration with Vitality/Discovery, we will conduct an RCT among Vitalitydrive customers. We will compare the effectiveness of fixed vs. contingent incentives, feedback vs. no feedback on driving quality, and simple vs. complex feedback formats. To inform the trial, we will also conduct secondary analyses of existing Vitalitydrive client data. We will randomize a stream of new Vitalitydrive customers who elect to install the DQ-Track device to one of three arms. We interpret differences in driver behavior across these arms as evidence for the role of played by incentives and feedback on driver risk-taking.

Primary Outcomes
Primary Outcomes (end points)
Primary Outcome Measure:

Driver Performance Score

Secondary Outcome Measures:

Harsh driving events

Claims and collisions

Primary Outcomes (explanation)

Driver Performance Score: The DQ Track device installed in the participants car records driver safety, which is rolled up into a monthly Driver Performance Score.

Secondary Outcome Measures:

Harsh driving events: The DQ Track device records each harsh acceleration, harsh braking, harsh cornering event. These are rolled up into a daily count.

Claims and collisions: We will measure any collisions or claims made on the insurance policy.
