Progressive's leaderboards cut drivers' handheld phone use by 27.6% in a trial

The trial recruited 1,653 customers already in Progressive’s Snapshot telematics program, all averaging more than 6.4 minutes per hour of handheld phone use while driving (Progressive’s safest customers log under one minute). Participants were split into five arms of escalating intervention over 10 weeks: education alone; education plus a free phone mount (‘Driving? Park your phone here’); and that plus a written commitment, disclosure of each driver’s own baseline, weekly goals below 1 minute per hour and habit tips.

Arm four added competitive gamification: weekly goal messages, points awarded for meeting goals and taken away for backsliding, and anonymized leaderboards grouping ten drivers with similar baseline usage. Arm five added money - a shared $2,000 prize ($15.63 each) plus $5 for topping the weekly board.

Arms one through three produced no significant reduction in handheld use. Arm four cut handheld usage 20.5% during the study and was still 16.2% below control through a 25-65 day post-intervention period. Arm five did best: a 27.6% reduction - 89 seconds per hour - sustained at the same level throughout the post-intervention window.

The result, published in PNAS (DOI 10.1073/pnas.2320603121), points to a cheap lever for insurers: paying drivers to behave better whenever prizes cost less than the crashes and claims they avoid. Automakers already use comparable gamification to nudge hybrid and EV drivers toward efficiency.

Group similar-baseline drivers into ten-person leaderboards, award points for goals and take points away for backsliding - competition beats education.

Drivers already knew handheld phones were dangerous - the trial's first three arms showed information, free mounts and even written commitments changed nothing on their own.

Leaderboards pooled only drivers with similar baseline usage, so every participant could genuinely compete instead of measuring against unreachable outliers.

Points were taken away for backsliding, a loss-framed structure that kept weekly goals salient - and the behavior held after the trial ended rather than snapping back.

Education and free tools rarely change habits; measurement plus peer comparison plus small stakes does - and the effect can persist after the rewards stop.

Both gamified arms kept their reductions through the 25-65 day post-intervention period, with the paid arm holding its full 27.6% cut. The study's framing suggests a path insurers could adopt: financial incentives scaled against avoided claims. No permanent program change was announced in the material.
