text: Colombia is also using Paris' strategy, but their "car-free" days are limited to once every year. Colombia has been using this stategy for 3 years and each year getting a better turnout of people participating. Violators who choose to drive on this day known as the Day Without Cars day, are fined $25. Their goal is to promote alternative transportation, interaction between citizens, limit individuals stress levels, and reduce smog. Heidrun Walter, a citizen in Colombia quoted, "When I drive my car I'm always tense. I'm much happier when I'm not behind the wheel." Haidrun is just one of many citizens who have expressed their interest in this new method.
