Motivating signage prompts safety belt use among drivers exiting senior communities.

The team taped a bright yellow sign that read "BUCKLE UP, STAY SAFE" to the stop sign at the exit of five senior communities. They watched drivers leave and recorded who wore a seat belt. They took baseline data first, then put up the signs, and checked again six months later.

Seat-belt use jumped from about seven in ten drivers to nine in ten the day the signs went up. Six months later it was still eight in ten. The cheap sign worked and the effect stuck.

Dagnan et al. (2005) followed the same signs for four more years and saw the same 25-point boost, proving the effect lasts with zero upkeep. Haring et al. (1988) and Berler et al. (1982) tried free sodas or raffle tickets instead of signs. Their gains disappeared as soon as the prizes stopped, showing rewards work short-term while signs work long-term. Van Houten et al. (2005) used a gear-shift delay prompt on non-wearers and got perfect buckling, but the device had to stay in the car. The sign wins on simplicity and staying power.

You can copy this tomorrow. Print "BUCKLE UP, STAY SAFE" in big letters, tape it to any exit sign, and watch the behavior stick for months. No tokens, no gadgets, no staff time. Perfect for senior centers, day programs, or any gated setting where drivers roll past one main gate.
