You should "declare a "mayday" over your radio" when you alone in zero-visibility conditions and unable to find an exit.
- Put on your warning lights and pull into the nearest parking lot or other safe location if there is dense fog or other conditions that restrict your visibility to near zero. If you can't find a safe parking space or parking lot, pull over to the side of the road as far as you can.
- Mayday is an emergency procedure word that is used as a distress signal in voice-procedure radio communications around the world.
- It is generally used by aviators and seafarers to communicate a life-threatening situation, but it is also used by local organizations such as firefighters, police forces, and transportation agencies in several nations.
- The word must be repeated three times in a succession during the initial emergency declaration to avoid being confused with another similar-sounding phrase and to distinguish a true mayday call from a communication regarding a mayday call.
Thus this is the meaning of mayday.
