A car horn is considered as a safety feature on your car, and if it is not working properly, it could be deemed as a minor fault on your MoT. If the feature is not working at all, it would cause your MoT to fail.
It is advisable to get your car horn fixed as soon as possible if you notice that it is no longer working.
