OAAA Heatstroke Campaign Shows OOH’s Local Power
A national heatstroke-prevention campaign from OAAA and the Ad Council shows how OOH (out-of-home) can combine broad reach with geographic concentration and contextual relevance.
Summer may be winding down, but a national campaign warning drivers about the dangers of leaving children unattended in vehicles is designed to remain visible well beyond the hottest months of the year.
The Out of Home Advertising Association of America (OAAA) and Ad Council launched the Heatstroke Prevention campaign July 9, bringing its “Stop. Look. Lock.” message to out-of-home inventory across the country. While the campaign places particular emphasis on warmer Sun Belt markets, OAAA President and CEO Anna Bager told Street Fight that the effort addresses a year-round, nationwide risk and will continue through April 2029 using the current creative assets.
For brands and agencies, the campaign is also an example of a broader evolution in OOH: maintaining the scale and consistency of a national medium while increasingly allowing marketers to concentrate exposure according to geography, audience, context, and local market conditions.
A National Issue With Local Relevance
Pediatric vehicular heatstroke remains the leading cause of non-crash, vehicle-related deaths among children 14 and younger, according to Bager. Since 1998, 1,056 children have died in hot-car incidents, averaging approximately 37 deaths annually. As of July 22, 2026, 13 children had died from pediatric vehicular heatstroke this year.
“The number of pediatric vehicular heatstroke deaths can vary from year to year, but these tragedies remain a persistent and preventable issue,” Bager told Street Fight.
Young children are particularly vulnerable because their bodies cannot regulate temperature as effectively as adults, but dangerous conditions can develop rapidly inside a parked vehicle even on relatively mild days. The campaign therefore focuses on establishing one simple habit: “Stop. Look. Lock.” before leaving a vehicle.
Concentrating OOH Where the Message Resonates
The campaign’s OOH assets are being distributed nationally, with particular emphasis on Sun Belt states including Arizona, California, Florida, Georgia and Texas. Bager emphasized, however, that vehicular heatstroke isn’t exclusively a warm-weather or southern-state problem. Hot-car deaths have occurred across the country, including in regions with traditionally cooler temperatures.
That creates a media strategy balancing national reach with geographic relevance. Creative and messaging can remain consistent across the country while additional exposure is concentrated in markets where environmental conditions make the warning particularly immediate.
For MULO brands and their agencies, the approach mirrors a familiar marketing challenge. National organizations need centralized creative and consistent brand messaging, but media investment can be weighted according to local conditions, consumer behavior, seasonality, store footprints, or individual market opportunities.
OOH Is Becoming More Precise
The campaign comes as advertisers are increasing their investment in OOH while the medium itself becomes more digital and measurable. U.S. OOH advertising revenue reached a record $9.46 billion in 2025, up 3.6%, with digital OOH increasing 10.5% and accounting for more than 36% of industry revenue. That momentum accelerated in early 2026. OOH generated a record $2.12 billion during the first quarter, up 7.1% year over year, while DOOH revenue increased 12.9%.
The bigger shift for brand marketers, however, may be happening in how the medium is bought. Research previously covered by Street Fight found U.S. marketers already using programmatic DOOH expect to increase spending by an average of 49% over 18 months, while its presence in campaigns is projected to increase from 34% to 52%. Ninety-one percent said they had incorporated programmatic DOOH into broader digital or programmatic activity during the previous year.
Those numbers point to OOH moving beyond its traditional role as a primarily broad-reach awareness channel. Programmatic buying, digital inventory, audience data, and improved measurement are giving advertisers greater ability to deploy national campaigns while adjusting execution according to local markets and conditions.

Reaching Consumers in the Right Context
The Heatstroke Prevention campaign illustrates why that combination can be powerful. OOH reaches consumers while they are driving, commuting, shopping, or otherwise moving through the physical environment where the desired behavior needs to occur.
The campaign isn’t limited to OOH. Television, radio, digital, and social assets reinforce the message across multiple touchpoints, while OAAA is encouraging media owners to donate available outdoor inventory to amplify “Stop. Look. Lock.” nationwide.
For marketers, that demonstrates how OOH can complement digital channels rather than compete with them. Digital and social can establish awareness and frequency throughout the consumer journey, while OOH can reinforce the same message in a specific geographic and physical context.
National Scale Meets Local Context
OAAA and the Ad Council plan to continue using the current creative through April 2029 rather than treating heatstroke prevention as a short-term summer initiative. That longevity reinforces another element of the strategy: a simple national message can remain consistent while its relevance changes by market, season, and consumer context.
For MULO brands and agencies, that’s increasingly where OOH’s value proposition becomes interesting. Centralized creative, national reach, geographic weighting, contextual placement, and digital execution can coexist within the same media strategy.
The Heatstroke Prevention campaign happens to apply those principles to a public-safety message rather than a commercial one. But the underlying model is increasingly relevant to brands trying to solve the same fundamental problem of how to operate at national scale without sacrificing local relevance.
