Carnival in Rio de Janeiro drives alcohol consumption up, and it also drives traffic risk up with it. Traditional safety warnings are easy to ignore in the middle of a street party.
Antarctica, as an official sponsor of Carnival, decides to make the safer choice feel easier than the risky one. With AlmapBBDO, they install a “beer turnstile” at a subway station where carnival groups gather. Scan an empty Antarctica can at the gate and the turnstile opens, giving you a free ride home.
Turning an empty can into a ticket
The mechanism is a direct behavior swap. Instead of telling people not to drink and drive, the brand turns public transport into the reward for doing the right thing. The “payment” is an empty can, scanned like a transit card, then collected at the turnstile.
In big-city event environments, the most effective safety interventions reduce friction at the exact moment decisions get made, and they do it with an incentive people can use immediately.
Why it lands
This works because it replaces moralizing with utility. The act is simple, public, and repeatable, and it reframes the end of the night as a next step you can take without planning. The real question is how to make the safer ride home easier than the risky one when people are already in motion. It also keeps the brand inside the solution rather than just beside the problem, which makes the sponsorship feel like action, not signage.
Extractable takeaway: If you want behavior change at scale, stop asking for restraint. Build a one-step alternative that fits the moment, then reward the safer behavior with access people already want.
What the beer turnstile gets right
- Reward the right behavior at the decision point. Do not place the incentive after the moment has passed.
- Use a token people already hold. An empty can is a frictionless “ticket” during Carnival.
- Make it visible. A physical gate turns participation into social proof.
- Keep the story one sentence long. “Scan a can. Ride free.” travels fast.
A few fast answers before you act
What is the Beer Turnstile?
A subway gate that accepts an empty Antarctica beer can as the “fare”, unlocking free travel during Carnival to reduce drunk driving.
Why is this more effective than a standard “don’t drink and drive” message?
Because it changes the default action. It makes the safe option simpler, faster, and immediately rewarding in the same moment people need to get home.
How does the can scanning work in practice?
The can’s code is scanned at the turnstile like a transit credential, then the can is collected as part of the exchange.
What results were reported for the activation?
Campaign write-ups reported usage of around 1,000 people per hour at the special gate, cited as 86% higher than conventional turnstiles that day, and a reported drop in drunk drivers caught of 43%.
When should brands use “brand utility” mechanics like this?
When a safety or public-good goal depends on real-time choices, and the brand can provide an immediate alternative action rather than just awareness.
