Are air horns illegal in the UK?

Air horns are not outright illegal in the UK, but their use is regulated under noise pollution laws. Using them in public places or during certain hours can lead to complaints and potential fines, as they can be considered a nuisance. Additionally, using air horns in a way that causes alarm or distress to others may result in legal action under public order offenses. Always check local regulations for specific rules in your area.
