What is the required number of red handheld flares for visual distress signals?

The required number of red handheld flares for visual distress signals is three. This regulation ensures that a vessel has an adequate number of flares to signal for help in emergency situations. Having three flares allows for redundancy in case some are not effective or are lost during use, and it ensures that a visible signal can be sustained over a period of time. This is particularly important because visibility can depend on various factors, such as weather conditions and the distance from which rescuers are trying to locate the distress signal.

The requirement also serves to enhance safety on the water, as it prepares boaters for potential emergencies, enabling them to attract attention effectively. Some may incorrectly advance the idea that fewer flares may suffice, yet having the minimum requirement ensures compliance with safety regulations and maximizes the chances of being found during a distress situation.
