However, there is an exception for New Year's Eve: "On 31 December and 1 January, they may also be set off by persons who have reached the age of 18." Authorities may further restrict this period in densely populated communities for firecrackers alone. In Reinickendorf, the reason given was: "In recent years, it has been noticeable that, especially during the day on New Year's Eve and New Year's Day, firecrackers are increasingly being misused and set off solely for their explosive effect. This practice poses a particular danger as it disturbs public peace and safety. During the day, there are more people out and about, which increases the risk of injury and property damage. In addition, the noise causes stress and anxiety in animals and humans, which can lead to dangerous traffic situations."
